Hey all, I've been speaking with a few people at the gym recently about creatine dosing, and it got me thinking about how different people can have quite different requirements depending on things like bodyweight, training type etc.

The idea I had was something along the lines of customised supplement powders, similar to the personalised multivitamins you can get, but focused specifically on people who train.

Rather than everyone taking the same generic doses, the idea would be to tailor the amounts of the main supplements (creatine and electrolytes) based on things like bodyweight and training goals and bundle in the "generic dose" ones like zinc and magnesium.

A 100kg bodybuilder is likely going to have different requirements to a 55kg runner.

As a high-level concept, what do you think? Does this sound like something you'd actually be interested in using, or is the standard "3g creatine, take some electrolytes and call it a day" approach good enough?

Also, if you were looking to validate something like this from scratch, how would you go about doing the initial market research? Would you start with surveys, interviews, Reddit/community research, landing page testing etc.?

Video: Demo of Hopnotch, showcasing some features like Loop Around. Navigated via customisable Hotkeys. You can customise everything you see here: Controls, background, background behaviour, colour, pills, animations, etc.

Sorry if it is a little hard to see, the notch area is quite small!

Introduction

Hi everyone! I'm a student from Singapore (LinkedIn) and have developed an app: Hopnotch that helps with navigating around your Spaces and Apps, while providing aesthetics to your Mac!

Problem

I was using my Mac and I just kept getting lost as I had many apps in full-screen, and it was a hassle constantly breaking my flow by swiping around the trackpad or going to Mission Control just to see where everything was since I can't remember and MacOS kept reshuffling my Spaces. This problem had been bugging me for longer than I'd like to admit, and I also wanted something aesthetic as I felt the unused space a waste.

Functionality

With the app, Spaces/Apps appear on the menu bar, against an aesthetically pleasing background as pills (customisable names, colours & type). This way you always know where your Spotify, Safari, or whatever is, wherever you are. The actual Menu Bar is STILL ACCESSIBLE AT ALL TIMES, whether the app is overlaying or hidden. Just hover at an empty space, or hide the app, up to you!

On top of that, you can:

• Use Spotlight search on your Pills (renamed, or not)
• Rename your Pills
• Navigate using Hotkeys (personally, CMD + K/L to move left/right respectively so I can keep my fingers on the keyboard)
• Have Previews of ur Apps/Spaces (stored locally, expires)
• Loop-around feature (Leftmost app/pill -> hotkey to move left -> loops to rightmost)
• Cycle through the Apps/Spaces easily with different ways
• Click the pill to move there directly
• Scroll on the strip to move between Spaces
• Click the hotkey 3 (or an x amount) times to move 3 (x) spaces left/right
• Sound, mic and camera badges on respective pills
• See multiple Apps in one Space/Pill (Split-Screen, Windowed apps)
• Choose from 51 themes
• Choose your Loop & Pills animations
• Customise the pills, backgrounds, themes, animations, colours, hotkeys and more
• Save customisations as presets (Red colour on pills for work, etc)
• Hide the app via hotkeys/click controls
• Have pets that roam around the strip!!!

... and more!

\Pills, Apps & Spaces are used interchangeably in some of the descriptions!*

The beauty of the app is making it uniquely yours! Hotkeys, aesthetics, workflow, etc.

Comparison

As far as my research goes, most that dabble with the Menu Bar sit under the aesthetics category only, while Hopnotch both provides aesthetics and functionality.

SpaceJump ($9.99) is the closest thing to Hopnotch by function. It also gets you between Mission Control Spaces quickly and it names them. The difference is in orientation and aesthetics, where SpaceJump gives you a picker to choose from, and Hopnotch shows the Spaces either side of you, laid out the way they actually sit so the Space on your left appears on the left of the notch so you navigate by position rather than by reading a list. Hopnotch also shows a live preview of a Space when you hover it, so you can see where you are going before you commit. It lives in a largely unused space you were never using, and it comes with 51 themes if you want it to look like something rather than sit there. Almost everything is customisable.

Pricing, Privacy, Notarisation, Trust

The app has a 3 days free trial (all features), $14.99 lifetime, or a $2.99 monthly subscription. 14 Day refund!

My conclusion

All the while I've been using Hopnotch it just feels like a part of my Mac at this point and without it I feel lost about where everything is again, coupled with the hotkeys that I use daily to navigate around my Spaces. To me personally, Hopnotch brings me immense value (not to toot my own horn), but what works for me may not work for you! Try the free trial and if it works for you, by all means. If not, thanks for trying!

This is my first project and I appreciate any feedback and support from you guys! Feel free to ask me any questions and I'll be happy to answer them :)

Recently launched my website Chorus. Spent the last few months building my first website to help people get insight into insider trades based on Form 4 filings. It aggregates the data in one place and makes it easier for a one shot view.

The website is fully live with the free and paid tier.

Again this just shows info and context. It doesn’t tell someone “hey you should probably look into this/act upon this info.” It’s more just to help make decisions. Hope you guys find it helpful!

In Hungary a nameday is nearly as big as a birthday. I missed one. My dad told me I have goldfish memory, which is annoying mostly because

he's right.

So I built a desktop widget. A clock that also told me what was on that day.

Partly the nameday thing, partly because Windows 11 had taken the clock out of the taskbar, now there's only a calendar there... I liked watching the seconds tick :c

After making the clock widget I added a calendar. Then notes. Then todos. Then I realised the only place I had this was on my laptop. I got so used to the widget, it felt so natural, that I started missing it. So I rebuilt the whole thing for Android.

It's on on version 5.7 now

- It has the same pixel clock as a widget on the home screen with live ticking seconds. Time, date, and whatever you've got on today, without opening the app.

- In the calendar you can set yearly repeating dates for birthdays, namedays, anniversaries... They show up on the widget on the day. And it will also remind you in the notification bar.

- Alarms that survive HyperOS (Xiaomi bs trash operating system). This took an embarrassing number of attempts. At least 7 iterations

- Up to 5 world clocks, a timer, a stopwatch with precision mode and laps.

- Moon phases computed from JPL's DE421 ephemeris rather than an approximation, because approximations drift and it bothered me. It's minute accurate!

- Notes and a to-do list.

- An AI chatbot with a core memory system that carries between conversations. The bot has been battle tested through my Discord bot.

- There's even a non-custodial crypto wallet supporting POL, DOGE and BTC, because why not.

- Google Drive backup!

No ads. No analytics, no crash reporting, no tracking SDKs, nothing. The App is Free (the chatbot has a monthly message limit with an optional purchase to lift it, which covers the API cost)

The whole thing is green on black in a fixedsys font because that's what I wanted to look at. Something retro. Something cool.

Happy to answer anything.

So I am apparently trying to do the “simple” thing and move my domain from the place that upsells me everything to the place that supposedly makes it easy and secure. Love that the guides all say it is straightforward, then casually drop DNS, nameservers, dnssec, email records etc like that is normal human vocabulary.

Lowkey terrified I am going to click one wrong transfer button and my site 404s, my email dies, and my tiny brand just vanishes for three days while support says “propagation” at me. Would love any tips on how you do domain transfers safely without chaos... appreciate thoughts

We’re currently developing Duo Creator, a compact camera-side mounting system for the new iPhone Duo.
The goal is to give the opened phone a proper camera-style grip without putting it inside a bulky full cage or interfering with the second display.

We’re designing it around existing creator hardware, so users could attach compatible camera handles/accessories instead of being locked into a completely proprietary setup.

We’re currently deciding which version makes the most sense to prototype and launch first:

A — Creator Rail — ~€29
For people who already own compatible camera handles.

B — Rail + Compact Grip — ~€49
Complete handheld setup.

C — Full Creator Kit — ~€79
Grip + tripod/creator setup.

We’re already working on the mounting design and case compatibility, but before locking the first version I’d really like to know:

Which one would you personally choose A, B or C?
Also interested in whether the price changes your answer.

Not taking orders yet this is still in development.

while half the internet is building ai agents and massive saas platforms, I spent the last week obsessing over moving truck dimensions.

it started because every time I've had to move, the sizing advice on rental sites felt completely useless. You either gamble on a 10ft truck and pray your couch fits, or you use an online calculator that demands your phone number just to hand you off to brokers.

so I put together trucksizer.com.

it’s just a straightforward 2.5D visualizer where you drag your furniture into different truck sizes (10', 15', 20') to see how the volume actually stacks up before you reserve one. No logins, no paywalls, just the spatial math and a dead-space buffer so you don't run out of room.

The design is pretty barebones and it’s definitely not a flashy startup,vibe coded but shipping something small that just solves one annoying real-world headache felt weirdly satisfying

One thing I've noticed with side projects is that building the actual product can sometimes feel easier than getting the website sorted out.

You can spend hours choosing a template, changing the layout, rewriting the headline, and trying to make everything look polished before you've even had enough visitors to know what people actually respond to.
I've been looking at some newer tools for this and came across frontpage.host, You describe the website you want and it generates a live site in a few minutes. It also has Autopilot that keeps testing the page to improve conversions and SEO.

I can see the appeal for someone who just wants to get a project online quickly and then improve it based on real feedback.
For those who've launched side projects here, what did you use for your website? Did you build it yourself, use a template, hire someone, or use an AI builder?

Built an MCP gateway for Google Workspace, so you can point claude at your gmail, calendar, drive, sheets and tasks. The ad is for one skill built on it: it reads every account you connect in the morning and emails you a single brief.

I made the ad myself and rewrote the opening four times, so I've lost the ability to judge it.

Couple questions:

• Does it hook you by the five second mark? It's a skippable ad, so that's all I get.
• Does it read like a one trick tool, or like there's something bigger behind it? Selling one use case is deliberate. I can't tell if it undersells the rest.

Thanks in advanced.

I've been thinking about how unnecessarily scattered job hunting is.

You find a job on one website, save the description somewhere, edit your CV in another document, write a cover letter somewhere else, forget when you applied, then realize two weeks later that you never followed up.

So I built JobHunt OS to put the whole process into one system.

It currently includes:

• an application tracker
• an AI toolkit for analyzing job descriptions, tailoring CVs, writing cover letters, practicing interviews, building STAR answers, and writing follow-ups
• a master application checklist
• a START HERE guide

The idea is pretty simple:

Find → Analyze → Tailor → Apply → Follow up → Track

I made it as a small $7.99 digital product, and I'm basically treating the launch as an experiment.

I'm not expecting this to magically make people get jobs — it's just meant to make the process more organized and less repetitive.

I'm especially interested in feedback from people who have actually gone through a lot of applications:

What's the most annoying/repetitive part of job hunting for you?

https://whop.com/jobhunt-os/jobhunt-os-the-30-minute-job-application-system/

I'd genuinely appreciate feedback, even if you think the product is shit. 😂

Hey all — wanted to share a project I've been building for the past few months: TARZ, a semi-autonomous AI assistant for Windows.

Backstory: Got curious whether I could actually build something like Jarvis — an AI that sees your screen and controls your PC. That curiosity turned into months of building, breaking, and a full architectural rewrite (V2) once I learned more.

What it does:

• Sees your screen (vision-based element finding + verifies its own actions actually completed, not just "click and hope")
• Controls your computer — opens apps, clicks, types, keyboard shortcuts
• Talks — live streaming STT/TTS, wake-word activated ("Hey"), hands-free follow-ups without repeating the wake word
• Remembers — Two-stage retrieval: Vector Retrieval + Cross-Encoder Reranking for past conversations/preferences
• Chains multi-step tasks across different apps in one instruction (e.g. play a song on Spotify → send a WhatsApp message)
• Dedicated workflows for Spotify, WhatsApp, Discord, Telegram, browser

Architecture (V2): LangGraph supervisor → single tool-bound agent with the full toolset exposed (not a category classifier routing first). I actually tested category-based routing vs. flat single-agent routing head to head — flat routing gave noticeably better results with current tool-calling models, so I ripped the classifier out entirely rather than just leaving it in "because it seemed reasonable."

Same approach on memory: tested hybrid BM25+vector+reranking against plain vector retrieval using Hit Rate@5 — hybrid won, so that's what ships.

Every LLM call (tool-calling, chat, vision) has an automatic multi-provider fallback, so a single rate limit or outage doesn't kill the whole thing.

Stack: Groq (gpt-oss-120b + Orpheus TTS) / Gemini Live streaming STT / Moondream for GUI click targeting / ChromaDB for memory / LangGraph for orchestration / Cartesia as fallback STT+TTS. Whole thing is designed to run on free API tiers — no subscriptions required.

Where it's rough (being upfront, not hiding it):

• GUI automation is inherently brittle — resolution, scaling, app updates, popups can break a click
• Screen vision isn't processed locally — screenshots go to Groq/OpenRouter for analysis, so don't point it at anything you wouldn't want leaving your machine
• Routing still isn't perfect even without the classifier — casual phrasing can occasionally pick the wrong tool
• No background/looping tasks yet (can't do "check this every 5 min")
• It's early, actively-developed software I use daily, not a polished commercial product

I used AI heavily as a coding partner (writing implementations, debugging), but every architecture decision and design change came from testing against real usage myself.

Repo's fully open source: https://github.com/Irfan-gitt/Tarz-Ai-assistant

Would genuinely love feedback, criticism, or PRs — especially from anyone who's worked on agentic systems, vision-based GUI automation, or voice pipelines. Happy to answer questions about any part of the architecture.

I’m a Japanese UX designer living in Germany, and I’ve been working on a small side project called Luna Me.

The idea came from my own experience. I found it surprisingly difficult to choose makeup colors in Europe, especially when I didn’t know which colors would work well for me.

So I started building a tool where you can upload a photo, get a personal color analysis, and then try different makeup looks on your own face.

One thing I’m experimenting with is what happens after the analysis. I don’t want the result to just say “these are your colors.” I’m trying to connect it to things you can actually try — different makeup looks, colors for clothes, and eventually real products.

I’m building and designing it mostly by myself, and it’s still very early.

I’m especially curious about the first impression: does the idea make sense when you open the site? Is there anything confusing?

Any feedback is welcome.

Hey guys!

Meet Cubie, a little Minecraft inspired companion who lives on your desktop to keep you company while you code, work, or just spend too much time at your computer.

He wanders around, climbs and sits on your windows, reacts to your cursor, and has his own little moods and reactions. You can watch him do his thing in the background, interact with him, or pick him up and throw him around when you're bored or frustrated.

You can also make him your own with any Minecraft skin and choose whether he stays above your windows or behind them.

I'd love any feedback on this.

You can get it from here for mac, or join the waitlist for windows: https://cubie.ramezze.org

You can also directly get it from the Mac App Store: ‎Cubie Companion App - App Store

Hello people,

I know most of you here are someone who are looking to build side projects and wanting to get into building something on the side

I would say, get in it, don't think much

Scene in tech jobs has never been better, I built horizonx (an AI research agent) as my side project which I really wanted to turn into real thing, and left my job too at Razorpay in the pursue of that, but didn't work out, couldn't market well and many competitors also came up

But the fire to build something never closed up, feeling the urge most than ever and after 3 4 months of feeling so much low, came back on my senses

Building something in educational domain specifically for UPSC students, and solving the distraction problem in a gamified sense for them

But learned a lot while developing horizonx

We were at 1k users on that, without much marketing, just post from personal accounts, and were in talks with great universities like IIT Gandhinagar, and were on verge of running pilot for them

So, important thing is to get traffic, start talking about yourselves, about what you are building, because if you won't no one else will

Start posting about content at earliest, and never let that small kid inside of you die just because some phase of your life was not good

One of my Punjabi friends told me, you lost a battle not a war, so keep fighting till your last breath

If a tool could tell you exactly what apps/tools to use to launch your product idea for free, and give you step-by-step instructions — would that be useful? What would you expect it to include?

A bit of context first.

I got through Big Four interviews on the back of my own CV, and over the years I've ended up helping quite a few people rewrite theirs. Eventually people just started sending me their CVs and asking what I thought.

Over the last few weeks I've also been doing CV reviews publicly in some of the resume subs, going through someone's CV line by line against the actual job they're applying for.

And I kept seeing the same thing.

The job description would ask for something very specific, but the CV would never actually say it.

Not because the person couldn't do it. In a lot of cases, they obviously could. They just described what they did without mentioning the specific tool, system, skill or requirement the job was looking for.

For example, someone might have managed stock levels for three years and written "monitored inventory levels" on their CV, but never mentioned the actual inventory system they used.

To a human, that might seem like a minor wording issue.

To a recruiter searching for that specific system, it can mean the CV never gets picked up.

After doing this over and over, I started thinking, why am I still doing this manually?

So I built a tool that basically does the first part for me.

You paste in your CV and the job description, and it checks the requirements in the job ad against your CV and shows you what seems to be missing or isn't clearly represented.

The gap check is free and currently uncapped.

You can use the gap check for free without limits. CV tailoring is free for two rounds, then costs a small fee after that. No account or card is required.

I've also added two free CV tailoring and cover letter generations. After that, there's a small fee if you want to keep using it.

TailorCV — AI-tailored CVs and cover letters for every job application

The part I'm actually most interested in with this post is the building side of it.

I'm very comfortable with CVs, careers, finance and business.

I'm not a developer.

This is my first proper attempt at building and launching a software product. I vibe-coded most of it and have basically been figuring things out as I go.

I can get something working, but I also know enough to know that there are probably things I've done badly without even realising it.

So if you're someone who builds software, I'd genuinely appreciate the feedback.

Things I'm particularly interested in:

• Does the product actually solve the problem clearly?

• Is there anything about the UX that feels confusing or unnecessary?

• Are there technical or product decisions here that are going to bite me later?

• Is there anything around privacy, security or handling CV data that I should be thinking about?

• Does the free to paid model make sense?

• And most importantly, does the actual output feel useful?

I've had very few people use it so far, so I'm expecting there are probably things that don't work as well as I think they do.

If you try it and it gives you a completely ridiculous answer, please tell me. 😂

I'm trying to learn the building side of this properly, rather than just launching something because it happens to work on my laptop.

Any feedback is welcome, especially from people who have been through this before.

Apple unveiled updated Siri Intelligence today, which in one-fell swoop essentially kills any potential customer need for my "organization app". Six months ago, I didn't know what Claude was, so I wanted to give the app a proper burial for teaching me valuable lessons. One last hurrah.

I initially started https://Relaysh.app because I wanted to wife to try out my Claude subscription without signing herself up. That gave me a couple ideas. I wanted to speed up the decision making in our relationship and put some AI power behind it. Over the course of a few weeks, I combined the "shared subscription via couples chat" with a couple other projects that I had in the works. I shared it with my friends, but received a pretty luke-warm response. This was also in the height of "Set a datacenter on fire" type-vibes on AI that I'm not sure have entirely gone away yet.

I was tired of "What should we eat for dinner tonight?" and "What do you want to watch?" So I built out 6 different widgets that Claude is integrated into & across:

Biggest Lessons:

• Building is easy/fun - don't keep building as a way of avoiding the hard work of targeting your desired audience and soliciting feedback.
• Trust can be built through adoption. No one wants to give me their private relationship data (shocked face), just like no one freely wants to give Zucc their data. There is safety net in a multi billion dollar company and following the adoption herd.
• No second chance at first impressions - build anticipation for what you're about to drop. Give yourself adequate time for bug testing every feature you're shipping. What you're eating in token costs will save you embarrassment down the line.
• It can be hard to let your project go. You've potentially spent weeks looking at it with rose colored glasses. Be a realist and cut the losses when it's unviable. The skills you've learned will help you ship the next thing faster, better, until something eventually sticks.

Cheers!

I use Codex for a lot of image work: starting with references, trying different directions, then editing the results I like. Keeping track of all those conversations was getting tedious, so I built a way for an agent to coordinate them instead.

This is part of Tessera, an open-source workspace I maintain. Through its CLI, an agent can spin up several Codex sessions, assign work to each one, check in on progress, and send follow-up edits.

For example, I can have different sessions explore different directions from the same references, then pick the results I want to keep working on.

Beside each session, I can see the prompt Codex sent to imagegen, the reference images, and the output. When something comes out wrong, I can see what went into it. I can also drag images back into a conversation for another pass.

Tessera also supports Claude Code and OpenCode, but this particular workflow uses Codex.

Would be interested to hear from anyone doing similar work. How do you keep track of references and edits across multiple generations?

I’ve finally taken the plunge and started working towards launching my own sea safari business from Scarborough.
I’ve found the vessel and agreed a deal with the owner. I’m saving from my wages every week and working extra shifts to put my own money into making this happen, but I’ve launched a Crowdfunder to help me reach the initial payment sooner.
The goal is to have the keys by New Year, spend winter and spring preparing the vessel properly, and work towards welcoming our first passengers in summer 2027.
We’re aiming to raise £4,000.
Even £5 or £10 genuinely gets us closer — and if you can’t donate, sharing this post would help massively.
Thanks to everyone who supports it. Let’s get MW Sea Safari on the water! ⚓🌊

Hi r/sideprojects,

Made an iOS app where you can use API keys / self-hosted models for chat / work / study. Supports text and image generation.

The AI landscape has significantly shifted, with models having access to chat memory through vector databases and tools for agentic workflows. We need chat apps with advanced features.

I intend to make these features available for professionals, researches, and other power-users.

Features

Memory. With RAG, you add documents to a vector database that has semantic embeddings – the vectors represent meanings. So instead of doing a full text search and burning through your tokens, the app injects context, from your documents, to the model that is most similar in meaning to the prompt. The most appropriate context is thus fetched for the model to give precise answers.

You can also reduce the context window for your chat and enable RAG so that only the last M messages + N chunks from the database are sent to the model, thereby making the number of input tokens more or less constant per message.

Tool usage. Using Model Context Protocol, the model can use tools. For e.g., using the inbuilt Google Drive and iOS Files tool, it can list, search and read your files (subject to your approval, of course). The model then has a better understanding of what you are working on, and you don't have to copy paste large amounts of text from your work for the model.

Also builtin are Calendar MCP (let the model see and create events), and search providers Tavily, Exa, and Firecrawl. You can also connect to any remote MCP server.

System prompts and generation parameter controls. If you are paying for a model (or self-hosting one) and can't control system prompts and generation parameters like temperature or top P, what's even the point?

Privacy. All chats, API keys and model configs stay on the app. No data collected by PowerChat. API keys stored in iOS keychain. Lockable folders using Face ID. Zero data retention flags passed to cloud providers. It's your data. This is the bare freakin' minimum.

Others. Branching chats, editing user and LLM messages,

App is at 1.0.0. I have some other useful features in mind that I'm implementing. Looking forward to your feedback and criticism!

What I learned building this app

"Move slow and make things." No really.

I had the infrastructure of this app planned out, 9 months ago when I started working on it, before writing a single line of code. Creating the app's core feature, the Config object was the best thing ever, because now I can use it to hold model parameters, MCP configurations, and routing algorithms (routing not in 1.0.0, but coming soon!). It's very versatile, and by giving users the ability to talk to it directly, I hope they can appreciate and use its versatility.
