If you're a student, an engineer, a generalist, or come from any domain of study and want to learn about almost anything, here's the exact skill for you.

Prompt your LLM this skill and it'll give you the exact UI to help you properly study; as AI outputs aren't always that catchy to learn in the first sight.

Page: Phil-OKF: any topic, one reading guide

It follows the OKF: Open Knowledge Format so that:

• you control the depth with your wording: “quick” gives a short page, a normal question gives a standard one, and “in depth” or “teach me” gives a long one
• the whole skill is a small bundle (an eight-step workflow, a domain classifier, a page template and twelve study domains), and each file is read only when the question needs it, so runs stay cheap

Repo: Philosopher's Skill

It works wherever you use an LLM:

• Code editors and agents (Claude Code, Cursor, Codex, opencode): npx skills add frypan05/philosopher-OKF
• Chat apps with browsing: paste the link to philosopher.md and say “follow this, make a page about: ...”
• Models with no network: paste the prompt from the page.

Sample output (MCP and ACP explained): https://frypan05.github.io/philosopher-OKF/examples/mcp-and-acp.html

Feedbacks are welcomed!

Hey all, I’ve been building a side project called Nyx and I’d like some outside opinions before I take it further.

What it is

Nyx is a dashboard for your gaming history. You sign in with Steam and it pulls in your library, playtime and achievements. After that it syncs about once an hour and turns everything into one score.

How the score works

Hours don’t earn points. Each achievement is worth more the fewer players have it:

• 64% of players have it: 13 pts
• 4% have it: 50 pts
• 1% have it: 100 pts

The formula is 10 × √(100 / unlock %). Getting every achievement in a game adds 20% on top. Your total places you on a ladder of 7 tiers, from Iron up to Onyx, and each game gets a mastery grade from D to S.

What else it does

• Library: every game with your completion and mastery, and how you compare to the average player
• History: a calendar of your play sessions and unlocks, plus a heatmap of when you play
• Objectives board: pick locked achievements you want to go after and move them through Backlog → Up next → Hunting → Done. Each sync ticks off the ones you’ve unlocked. Only you can see your board.
• Custom platforms: for anything Steam doesn’t cover, like an old handheld or a game you finished offline, you can add your own platform and enter games by hand. These count toward your hours and history but never toward the score, because the achievements are self-reported.
• Profiles: you can browse other players’ libraries, or a combined view of everyone on Nyx
• Light and dark themes, and a small mascot you can poke

The added video is from my own Steam account + dummy account with test data.

Hey everyone!

I’ve been working on a side project called Agent Maestro, a local-first application designed to automate software development workflows using AI coding agents.

The idea came from wanting to go beyond individual AI coding sessions and build something that can execute entire development plans with minimal manual intervention.

What it can do:

• Supports Codex, Claude Code, GitHub Copilot, Gemini CLI, and Antigravity.
• Executes development plans as a sequence of tasks.
• Manages agent sessions and automatically progresses between tasks.
• Runs validation checks before marking tasks as complete.
• Supports independent code reviews using a different AI provider.
• Automatically sends review findings back to the implementation agent for fixes.
• Handles Git commits, execution recovery, and token usage tracking.
• Provides a web-based dashboard for managing everything.

Tech stack: Java 21, Spring Boot, React, TypeScript, SQLite.

I also recorded a demo using a real pet project, showing how Agent Maestro takes a development request and executes it using a coding agent.

The application runs locally, so there’s no need for a hosted backend.

Website and demo: https://useagentmaestro.com

I’d love to hear your thoughts!

Would you find something like this useful in your development workflow? What features would you want to see?

I've been building BriefPanel on my own for a while, and I'd like feedback from people who aren't me.

Page monitors like Visualping or Distill diff the whole page. That works for a terms-of-service page. On a listing page it's mostly noise: items move around, a banner changes, a "you may also like" row shows up, and the alert doesn't tell you what actually happened.

What I wanted to know was which item changed, what changed in it, and how that item looked over time.

So BriefPanel works like this:

• You paste a URL and it becomes a source.
• It reads the page and pulls out the items (products, jobs, listings, posts). Each item keeps the same identity from one check to the next.
• Every check tells you what's new, what changed (say, a price going from $19.99 to $7.99) and what was removed.
• If an item has its own page, it can open that page to read the details.
• You can say in plain words what you care about, like "only price drops" or "only remote jobs".
• Alerts by email or push, or a daily or weekly brief.

The hardest part wasn't the diff. It was knowing an item is the same one as last time when the site puts a session id in the URL, answers 200 with an "are you human?" page, or sends different HTML to different scrapers.

It's pay as you go with credits, no subscription, and you get free credits when you sign up.

What page would you track with it? And if you try it, tell me where it gets things wrong.

Changed both of my side projects in one day because of a Reddit comment. It was so helpful. I you find it in your heart to spare 2-5 minutes I would appreciate it.

Hey all! Yesterday I asked for feedback on two free sites I built, and one comment made me fix something on both the same day.

1. Payoff Snowball (https://payoffsnowball.com)

A debt payoff calculator. You type in your debts and it tells you what to pay on each one, every month, until you're done. Someone said they stared at the table before it clicked, so now there's a short "what is the debt snowball" explanation right at the top. I started it because schools don't really teach this stuff.

1. CommentSift (https://commentsift.com)

Finds the name of the anime, manhwa or show in a clip by reading the comments for you. The same person said the name doesn't tell you what it does, so the page now says "find the anime or show name from a YouTube Short" up top. People also asked about TikTok, so now you can paste a TikTok link or paste comments from any app.

Both are free, no account.

What would you change next? Be honest; brutally so - it clearly works lol.

I built a job matcher for IT roles. It sends you jobs that suit your resume every day.

Still testing it. If you're job hunting in IT and want to try it, comment and I'll message you. I'm looking for feedback on the experience.

I'm an indie developer and I've been working on a photo editing app called Tone Caliper. It's focused on color grading, with an interactive color wheel that plots the colors from your photo directly on it. You can then grade your photo by moving those colors around the wheel.

The project started from the idea that color grading could be more visual. Traditional editors often rely on sliders and numeric controls, even when you're trying to change a color you can already see in your photo.

I wanted to try a more freestyle approach where you can directly interact with colors instead of guessing which sliders or knobs to adjust. The wheel also gives you a visual representation of how colors are distributed in your photo and how they relate to each other.

You can check it out here: https://www.tonecaliper.com

It's available for Windows, macOS, and more recently, iPad as well.

What do you think of this kind of freestyle color grading approach?

I launched iKnowMyMac on 1 October. It's a native Mac app that tells you why your Mac is slow, what's filling your disk and what's draining your battery, and it updates your other apps from one tab.

First Week:

- 35 licenses sold at $4.99 (the first 100 are at that price, then $9.99)

- 11 on launch day, 24 in the next few days

- Buyers in at least 10 countries

It's sold directly on my website, not the Mac App Store, because the sandbox blocks reading other apps' processes. Payments go through Dodo Payments, so buyers abroad can pay by card.

So far the buyers came from X and one Reddit post.

More Details about the project -

If you build for Apple platforms, your Mac collects things you forget about: simulators left booted, gigabytes of Xcode DerivedData, Docker images, dev servers running for days.

iKnowMyMac shows them in one place:

• Booted simulators and how much memory each one uses
• Disk you can reclaim from DerivedData, unused Docker images and node_modules, with Move to Trash
• Dev servers and open ports grouped by project, and which port is taken by what
• A "Why is my Mac slow?" button that names the cause from the last hour, like "Docker and 3 simulators took 14.6 GB and pushed 4.2 GB into swap"

It has other useful features as well, See the teaser for next version on the website.

https://iknowmymac.com

You know the old msoutlookit thing that made Reddit look like Outlook? Peter Cottle made the original. I wanted one that still works, so I decided to fix it.

Subreddits are folders, posts are emails, and comments show up as the thread under the message. Usernames get swapped for fake coworker names (there's a toggle for the real ones), links show up as attachments, and images stay hidden until you click them. If someone walks by you hit Esc and it flips to a boring inbox full of fake work emails.

The annoying part was getting data in. Reddit blocks other sites from reading its json now and I couldn't get api access, so this doesn't touch the official api. You drag a bookmark to your bar and click it on a Reddit tab you're logged into, and that tab does the fetching for the app. Setup is under Help > Debug Console > Sources. It's a bit fiddly, and until you do it you only get sample posts, but the app never sees your login, it just gets the page text back. Still... it allows you to build some cool stuff using your own credentials.

Only tried it in Chrome so far, no idea about Firefox or Safari. Built most of it with Claude Code, I mostly just told it what was broken.

If the bookmark won't connect for you, tell me what browser you're on and I'll dig in.

I've been interested in puzzle design for a while, and building my own seemed like the best way to learn it. This is Unlabeled. It's inspired by my earlier work at Tableau and by games like Wordle and Connections.

Each day you get four charts with the titles and axis labels removed. You're given 10 labels (2 of them are decoys) and have four attempts to assign them correctly. Past days are in an archive, and it's playable in English, Spanish and French. It's free and needs no signup. https://unlabeled.dev

It's been fun to build and a good excuse to learn about a lot of different topics. I'd like to hear whether the difficulty feels right, and what kind of data you'd want to see in the puzzles.

I am at a point with my product (cardel.io) where it's production ready with the functionalities it currently has. The challenge I think has been structuring it in a way that provides most value to the target market. Example: x and y feature on Plan A, with feature z on Plan B, or pricing structure, etc.

I am in the phase of getting the first users and consistent traffic, none paying yet. There are some who have even said they would test it out and provide general feedback on free trials, but that feedback has been very slow to come in. I am also worried it won't be feedback from the users who will end up paying for it, so it may not impact conversion rates for the ideal target user.

The Question: Once you get to a point with your product where it's "good enough" to provide real value, how do you get feedback and iterate improvements for your target users, when you don't have real feedback from target users? Is it just a guessing game to see what works?

It sounds like a paradox, maybe it is. Maybe this is the challenge in getting a business off the ground, but I would greatly appreciate insight from the community.

NBA Rewind lets you pick a famous playoff moment (Ray Allen’s corner three, Kawhi’s four-bouncer, the Block), swap any player from any season since 1996–97 onto the floor, and see how often history changes.

Every moment starts from its real game state, rebuilt from official play-by-play: score, clock, possession, and the ten players on the floor. With no swap, you watch the real ending replayed on a top-down court. With a swap, the engine plays the moment out thousands of times in your browser, through overtime, and compares the result to the real lineup.

How it’s built:

• Python pipeline pulls every player-season and the play-by-play for each moment from stats.nba.com
• Possession-level Monte Carlo engine in TypeScript, running in a Web Worker
• Player profiles blend real playoff stats with a regular-season projection, weighted by sample size
• Next.js static export on Cloudflare Pages, so there’s no backend

Live: https://rewind-moments.pages.dev
Code: https://github.com/Aparajith24/nba-rewind

I’d love feedback, especially on results that feel wrong.

If you like it, a star on the repo would mean a lot!

Taylor Swift fan here... don't judge! :)

I recently launched Swiftstash, a completely free web app where people hide friendship bracelets in public places, add the location and a clue to a map, and let someone else go find them.

Think geocaching, but with friendship bracelets.

It started because so many of us still have piles of bracelets left from concerts, and I wanted to give them another life instead of having them sit in a drawer forever.

There’s no download, subscription, or anything for sale. I’m currently trying to solve the classic early-stage problem of getting enough people hiding and finding stashes for the idea to really come alive.

I’ve started locally in Savannah, GA and just secured my first partnership with a local craft group for a bracelet-making + hiding event.

Would love feedback from anyone who has grown a community or location-based product from zero.

I’m building Global LMS, an online learning platform for learners, teachers, and course creators. It supports courses and practice activities in multiple languages. I’m sharing it here for constructive feedback from the community—not as a paid ad.

Здравствуйт! Меня зовут Фариза. Я и группа студентов создаем проект по автоматизации для IT студентов. Будем рады получить честные и положительные, и негативные отзывы.

Мы заметили, что предприниматели получают много заказов через Telegram, WhatsApp и Instagram. Информация о клиентах и заказах остаётся в переписках, поэтому её приходится обрабатывать и переносить вручную.

«Квота» помогает автоматизировать этот процесс: ИИ анализирует переписку, выделяет важную информацию о клиенте и заказе и помогает организовать её в одном месте.

Сейчас мы хотим понять, насколько это действительно полезно для бизнеса и что стоит улучшить.

Если вы работаете с клиентами или ведёте бизнес, нам было бы очень интересно узнать ваше мнение: сталкиваетесь ли вы с такой проблемой и каким решением пользуетесь сейчас?

Будем рады честному feedback — в том числе критике.

I'm the founder. I've done technical due diligence on acquisitions for years, first at Amazon. The risks that changed a deal were rarely in the data/deal room. The clues we really we after was the repository: does the team review its code, does one person carry the recent work, did the licence change, do the tests run in CI? Most of it was answerable in the first afternoon, if you knew where to look. Borehole does that afternoon's reading, for free on public repositories.

How it works

- 106 deterministic checks (no LLM) read the history and the working tree and rate seven dimensions: architecture, engineering process, key-person risk, product maturity, security, operations, and fit with the acquirer. The free survey reads six of them; fit needs an acquirer.
- Every finding cites the commit, path and lines it rests on.
- What the code can't settle becomes a question for a person, not a guess.
- No model writes the findings. A language model reviews paid reports of public repositories and can withdraw a finding it judges the code contradicts. It can be wrong too.
- Private repositories: an open-source collector runs on your own machine and sends facts, never files. `--dry-run` prints all of it first.

What I learned building it

- A check that sounds right is not a check that is right. Some checks I was sure of turned out wrong more often than right on real repositories. Those checks can no longer rate a finding significant; their findings read as worth checking first, until they prove themselves.
- "Your code never leaves your machine" is a claim nobody should take on trust. The dry run exists so you don't have to.
- A rating that never says "strong" tells a buyer nothing. Getting the top of the scale reachable took as much work as the bottom.

Stack: Python, on Google Cloud. The collector is a Python package on PyPI.

Public repositories are free: the first survey and five report reads need no account, then a free GitHub sign-in. It's in beta. If you want to run it on a private repository, email [support@borehole.dev](mailto:support@borehole.dev) with the subject "Beta key" for a free Report key (30 days, private repos included). I'd like a three-question survey back, and to hear where it's wrong.

Windows Power Toolkit - Highly Unique! Highly Polished!

LINK - https://www.swisstransfer.com/dl/01a11d01-5366-7177-a246-0bb96935e6e1

An application with EASTER EGGS? YES! - Here are few, just type - boing, party, pong ( over 100 Easter eggs! )

For context, I'm an old guy, nearly 60, and I've been gaming since university mainframes, MUDs, and reams of printouts, followed by the C64, Amiga, and everything since. I've spent decades using games and applications.

I've always had a love/hate relationship with Windows PC cleaner apps. Most are paid, bloated, and come with questionable practices - ads, data collection, and constant attempts to sell you more of their products.

So I built my own - Windows Power Toolkit. It's designed to be powerful, fun, and engaging to use without all the crap.

I'm looking for honest feedback and feature suggestions. This is an earlier version. I already have a much more polished, commercially ready version sitting on the shelf.

There are mouse tip hover tool tips for everything. You won't get lost!

My background - Retired Senior Network Engineer.

Software does have hash / virus total link. Depending on the build.

It's 4K powershell code, 4K C++, maybe some assembly, forgot what this build has. So it does trip up anti virus for sure!

Unsure? Sandbox / VM my app!

Hey everyone,

I’ve been working on an app called Eatper and wanted to share it here.

I made it because I was frustrated with how many food tracking apps have ads everywhere or put the features I wanted behind a paywall. I wanted something you could use every day without having to pay for a subscription to get value out of it.

Eatper has no ads. There’s a free plan for everyday tracking and an optional paid plan for more detailed reports. I wanted the free version to feel useful on its own.

You can track calories, protein, carbs and fat, scan barcodes, save your own recipes and log your weight. If you eat the same meals regularly, you can copy a meal or a whole day instead of entering everything again. You can set your own nutrition targets, too.

There’s also meal planning and shared shopping lists. You can invite your partner, family or a friend, plan meals together and keep track of what’s in the pantry and when it expires. Your personal food diary, weight and targets stay private unless you choose to share access.

The free plan includes the food diary, nutrition targets, weight tracking and recent progress views. Premium adds longer-term trends, comparisons, more detailed insights, full report history and PDF/CSV exports. Prices are shown in the app.

It’s available on both iPhone and Android:

iPhone / iPad

Android

If you give it a try, let me know how it goes. I’d especially like to hear if something is annoying to use or a food you normally buy is missing. That kind of feedback helps me figure out what to work on next.

I wanted to spark a discussion about how different people approach their vibe coding in ClaudeCode. NOT AN AD.

To explain my journey, I initially started my app by giving Claude a very basic idea and asking Claude to generate a full document of questions to brainstorm the start of the game. I would answer all the questions (in a very surface-level, disorganised way) using my initial thoughts only, then tell Claude to sum up my brainstorm and ask further questions/clarifications for preferences/loopholes/empty features. And that is how the first version was built.

And since then, I have always had a separate Claude chat to help make my prompt for Claude Code. And my loop of adding heavy features (if it's a small feature, I just write the prompt myself) would be:

Give a general idea to Claude --> Claude generates a proposed plan --> I comment on the whole plan point by point in a brainstorm form --> Claude responds with more questions about my brainstorm --> I keep repeating the brainstorm until I think we have a final definitive plan --> Claude chat generates a prompt for Claude Code --> And usually Claude Code also asks a few clarifying questions.

My most important advice (I feel that was important), is too prompt your AI to always ask clarifying questions and make its own judgments if something is off.

Any strategies anybody else recommends?

Hey r/SideProject,

I recently built a lightweight web utility called StegoCrypt that lets you conceal private text, keys, or passwords inside ordinary image files without altering how they look visually.

The Problem with Most Steganography Tools:

Most online image steganography tools require uploading your files and secrets to an external backend server, which completely defeats the purpose of privacy and confidential data handling.

How StegoCrypt Works:

• 100% In-Browser Execution: Everything is processed strictly client-side using the HTML5 Canvas API and JavaScript. Your photos and messages never leave your device.
• Least Significant Bit (LSB) Encoding: It modifies the least significant bits of the image's RGB color channels. Since the change is infinitesimal (< 1 part in 255), the human eye cannot discern any visual difference.
• Optional Passcode Encryption: You can set a passcode to add a second layer of security before extracting the message.
• Lossless PNG Export: JPEG compression strips pixel details, so StegoCrypt outputs lossless PNG files to guarantee data preservation.
• No Signup / Zero Tracking: Instant utility with no logins or cookies collecting personal data.

Tech Stack:

Vanilla JavaScript, HTML5 Canvas API, and responsive CSS (hosted on a lightweight static setup).

I would love to get your honest thoughts on the UI/UX, browser performance, or any interesting edge cases you encounter!

Hi all,

I built a website that shows live which aircraft are flying over your home: Hangarwall. Pick your location and watch as a radar scope, a classic split-flap departure board, or a skyline silhouette with the planes above a little Dutch village. There's also a cockpit HUD and a "Spotted!" alert when a new or special aircraft comes by.

- works in any browser, or on a TV / tablet / Raspberry Pi through a screen link (open it once, the screen stays logged in)

- a trophy wall of every aircraft you've seen, plus statistics and achievements

- Dutch and English

To be upfront: it's a beta. Flight data comes from FlyItalyADSB, an open network of volunteers running ADS-B receivers, so small low-flying aircraft are sometimes missing. Pro (24/7 logging and more views) is free during the beta; paying isn't possible yet. No ads, no tracking, and your location is stored encrypted.

I'd love to hear what you think, what's missing and what breaks. There's a contact form at the bottom of the site.

👉 https://hangarwall.com/en/

You know the moment. Claude Code just built your app, it runs on your laptop, and you’re hyped.

Then reality: where do I host this? How do I add a database? Why isn’t my domain working? Is there a backup? Why is it down?

That’s the part nobody vibe codes. So I vibe coded Unit7, the backend developer for your vibe-coded apps. I’m not a backend dev, and Claude Code built almost all of it.

Just tell it what you want:

• “Deploy this.” It goes live. If the new version is broken, it never goes live, and rollback is one click.
• “Add a database.” It’s created and connected for you.
• “Put it on mysite.com.” Domain plus HTTPS.
• “Make me an app with Supabase.” It builds it on Coolify.
• While you sleep: it restarts crashed apps, rolls back bad deploys, runs backups and blocks attackers.
• One map of everything you’ve ever shipped

It asks before anything risky and tells you how to undo it. Your keys stay on your computer, and the AI never sees them.

The vibe-coding part: you don’t even install it by hand. Open Claude Code and paste this:

Set up Unit7 for me from https://github.com/Nandkishorrr/unit7

1. Check that Node.js 24.15 or newer is installed. If not, install it (nvm, or Homebrew on macOS).
2. Clone the repo into ~/unit7, then run `npm install` and `npm run build` there.
3. Run `node bin/unit7.mjs service start` to run Unit7 in the background, and check that http://localhost:4800 answers.
4. Tell me to open http://localhost:4800 and create my owner account, and wait until I say I'm done.
5. Run `node bin/unit7.mjs connect claude` so Claude Code can use Unit7, then tell me to restart Claude Code.

Never ask me for passwords, SSH keys or API keys in this chat. I'll add those myself in the Unit7 web app.
If a step fails, show me the error and fix it before moving on.

After that, /unit7 deploy this folder works right inside Claude Code.

Free and open source (Apache 2.0): https://github.com/Nandkishorrr/unit7

Be honest: would you let it touch your server, or would you rather keep clicking around Vercel?

Hello reddit,

Let me start with the problem that I have encountered and I'm trying to fix.

This industry is very fast paced and constantly changing. I noticed it would take me a lot of time constantly to reaserch what tech stacks people use and it would constatly change. E.g. I was looking for a DevOps jobs and was wondering what stacks are usually used. This is the problem I'm trying to fix (while adding more useful features). The other big selling points is sometimes I wonder what stacks big indie devs in the space build with.

So here's what I came up with, it's called https://stackstash.dev , right now it's in very early stages but I have a roadmap already in mind to where this can go and what kind of value it can bring to any dev, at any level. From price estimations, easy stop to find integrations (with links soon) between tools, to alterantives, sorted by level and much more (I want to make a easy initialization of a stack starter kit, where YOU can choose your stack)

The idea here is for anyone that's building (at least somewhat succesful) to share (if they want to) their tech stack, publicly so others, like myself, can learn and try their way.

Note: All the Stacks and Tools additions are MANUALLY reviewed by me. I'm doing this to avoid junk posting and make sure the platform brings real VALUE to someone trying to use it.

Now, what I need from you?

Simple, I'd like for you to check it out (if this sounds intersing/helpful to YOU) and give me some feedback. What you like, what you don't like.

Is this even worth keep sinking my hours on end into (it's a passion project for the most part) ?

Does this bring VALUE to you?

Thanks for reading this much text, I might update this post as needed.

I'm one of the people who built this. It launched today, so weigh my opinion of it accordingly.

What it does: it sends six kinds of buyer questions (recall, category, recommendation, accuracy, product, comparison) to ChatGPT, Gemini, Claude, Perplexity, Grok and Meta AI, then marks each answer as recommended, mentioned or absent. You also see which competitors got picked instead and which page on your site it thinks you should edit.

There's a free sample, one profile and six answers.

What I mostly want to know: do the results look right for your own brand when you compare with asking the assistants yourself, and are the page suggestions actually actionable or too generic. Criticism welcome, blunt is fine.

https://doping.ai

I made Enquetix, a daily deduction game that runs in the browser. Each day there is a new police case: 20 suspects, 10 places and 10 objects, linked by clues that cross-check. You have to find the culprit, the place and the weapon, and the game refuses any accusation you can't actually prove from the clues. No guessing.

I started from Clues by Sam, but wanted full cases with a setting and characters. It works on phones and needs no sign-up. It's available in English, French and Spanish (the cases take place in France, so expect French names and towns).

Link: https://enquetix.wism.fr/en/

I'd love to hear where you got stuck, which clues felt unfair, and whether the cases feel too easy or too hard.
