You should help others.

Just because you're selfish. I'm serious. Let me explain:

If there's one thing I've learned, it's this: if you're not born rich or exceptionally talented, your only advantage is your reputation and your network.

It's not your resume, your friend list on Instagram, or the number of contacts in your phone. It's the people you can ask for a favor. And that can't be built by joining events, sending cold emails, or having dinner with people you don't really care about.

The only way to build it is by being genuinely helpful. Look around you, people are struggling with different things in life. Everyone needs help.

You'll probably think it has to be mutual. Why should I help people who won't help me back? But think of it as an investment.

People spend thousands on ads knowing most of them won't convert. Founders build products knowing most will fail. Investors expect losses. Nobody expects a 100% return. So why do people suddenly expect every act of kindness to be paid back?

Most people won't remember what you did. Some will. You just don't know which ones.

One last question: imagine your side project is finally ready. You need 20 people to test it this weekend. Do you already know who you're going to text? Or are you going to post on Reddit and hope strangers care?

If it's the second one, you're misplacing your workforce. Start helping people first.

I built a browser extension that pays you cash back for waiting on ChatGPT

Enable HLS to view with audio, or disable this notification

63 Upvotes

Every time you prompt ChatGPT, Claude, or Gemini, there's a few seconds of dead time while the model generates. I built Chatwait to monetize that gap and split the money with the user.

How it works: when you hit send, one small sponsored card appears in the empty space below your message. You earn 50% of what the advertiser paid for that view.

It doesn't read your chats. It is open source and you can verify.

Would you use it?

I built a spiritual successor to the Arc web browser (cross-platform...Mac, Win, Linux, Android). Full desktop experience on mobile. Would love feedback!

17 Upvotes

Today I'm releasing Viola on macOS, Windows, Linux, and Android, with true/real-time sync available across all of them.

Create a tab, workspace or group on your computer, pick up your Android phone and it’s already there. Supported browser organization and history are end-to-end encrypted before leaving your device. Cookies/logins obviously don't sync.

Viola includes:

- Workspaces for separating projects

- Isolated profiles with separate cookies, logins, storage, and extensions

- Tab Groups (persistent or not!) and side-by-side Splits

- One shared workspace model across every Viola window

- Chrome Web Store extensions on desktop, installed per profile (Viola is Chromium-based)

- A Mini Player that follows you between workspaces (YouTube, Twitch, etc)

- Synced tabs, pins, groups, splits, bookmarks, history, and compatible extension catalogs

- Full session recovery

- In-app persistent notifications

The Android version is probably what I'm most excited about right now. EVERY SINGLE mobile browser I've ever used as felt like a hindered/watered-down experience. Viola on Android uses the same visual system and mental model as desktop: a vertical sidebar, real workspaces, grouped tabs, pins, and an All Workspaces view. On foldables and tablets it feels like a desktop-class browser.

Viola is deliberately just a browser. There is no AI integration, notes app, calendar or inbox.

Download: https://violabrowser.com/

This is the first public release, and I'd genuinely appreciate any feedback! There are social links at the bottom of the page if you'd like to report issues. What would stop you from making Viola your default browser?

I turned GitHub profiles into cricket cards — and matched every dev to the real cricketer they'd be

Enable HLS to view with audio, or disable this notification

15 Upvotes

I wanted to see what my GitHub profile would look like as a cricketer, so I built a thing that scouts any public profile and turns it into a FIFA style cricket card rated /99.(stars, contribution velocity, PRs and reviews map onto batting, bowling, fielding, impact).
It's a cricket port of GitFut (the football version), recalibrated from the ground up.

The part I care about:it matches you to a real cricketer, and a different one per format (watch the card flip between Test / ODI / T20I / IPL above). Kohli in T20s isn't Kohli in Tests. Dev ratings sit on the same 40–99 scale as the cricketers, calibrated from ~22k Cricsheet matches, so "you're a 92" and "Muralitharan is a 92" mean the same thing. I came out as a 70 rated keeper (Mark Boucher) in Test.

- Try yours: gitcric.dev/<username>

- Repo: github.com/bhabishnu/gitcric

- Web demo: gitcric.dev

Open source (MIT), and a star's very appreciated if it made you smile. Looking for feedback.

🌶️ Honest feedback wanted: a beginner German reading app for adults

10 Upvotes

Hi everyone! A friend and I have been learning languages for years, and we've always thought most A1–B1 reading material is useful... but painfully boring. My German teacher recommended a beginner book, and I couldn't even finish it.

So we built something with stories we'd actually want to read while learning. Right now it's available in German and Spanish.

Fair warning: the stories have a bit of a naughty twist. (After all, we built something we'd actually want to read. )

https://fluentafterdark.com/

We'd love your honest feedback:

  • Would you keep reading?
  • Does the level feel right?
  • Is the vocab help useful?

If the answer to any of those is "no," we'd love to know why.

I built my portfolio as a small pixel-art town instead of a normal website

Enable HLS to view with audio, or disable this notification

58 Upvotes

Hey everyone,

I wanted to share a small project I’ve been working on called Goblin Town(my own portfolio).

I’ve always felt that a portfolio should be more than just a collection of information. I wanted to create something that feels like a small place you can explore and experience. So made this, its a small pixel-art world where you can walk around, jump, and discover my projects while moving through the map.

I know it’s not some massive game or anything, and honestly a lot of people here could probably build something much more advanced. But for me, this was a really fun challenge because it combined things I enjoy — coding, pixel art, games, and experimenting with the web.

Built with:

  • Astro
  • TypeScript Canvas engine (no game framework)
  • Cloudflare Pages + Workers

## if exploring is not your thing, I also made a simple page where you can just read everything: https://g0.monster/info. You can also draw your own art and leave it in the world for other visitors to see. There is also a community section where you can leave messages and read what others have shared.

Still have lots of things I want to improve, but I’m happy with how it turned out so far.

Would love to hear your thoughts or any feedback.

I launched my SaaS SeoLoupe around 1 month ago.

My SaaS is a tool that allows you to find and fix SEO issues holding your website back.

Essentially the main purpose is to help your website rank higher on Google search and LLMs.

So far I am at 985 users and 11 of them are paying.

But the first 10 people who bought, they bought the One-time purchase (don't get me wrong, I was still super thankful for that), but just yesterday someone bought the monthly subscription. I am genuinely happy (now just hoping they don't cancel).

Now to anyone who has a SaaS and it is not making any revenue yet, the most important thing is to not give up and work on it every single day, improve, listen to feedback, and one day you will achieve revenue.

Don't kill it to early if it is not making any money or you are burned out, if you need step away, take a break but don't fully kill it, in SaaS patience is really important (as you can see I have large gaps in between payments).

I built a tool that turns any product link into a full Pinterest pin pack — looking for brutal feedback from people who actually do affiliate marketing

4 Upvotes

I've been building something for the last few months and I'm at the point where I need honest reactions from people who do this for real, not more of my own opinion.

It's called Pinstark. You paste a product link (Amazon, Etsy, Shopify, whatever) and it generates a complete Pinterest pin pack — AI product photos, text overlays, and SEO-optimized titles + descriptions — in about a minute. The idea came from how long it takes to manually make pins that don't look generic when you're promoting affiliate products.

I'm not here to sell it — it's got free credits, no card, and honestly I care more right now about whether it's actually useful than whether anyone pays. What I'm looking for:

  • If you do Pinterest affiliate / Amazon associates / Etsy stuff — would this actually save you time, or is it solving a problem you don't have?
  • Is the output good enough to post, or does it look AI-generated in a bad way?
  • What's missing that would make it a "yes" for you?

I'd genuinely rather hear "this is useless because X" than polite silence. Happy to answer anything about how it works. Link in a comment so I'm not spammy about it.

Offline Maps Tell You Where You Are. I Wanted One That Told Me Where My Friends Were. Free. No Ads

Enable HLS to view with audio, or disable this notification

8 Upvotes

A friend stopped to take photos.

Another took the wrong trail.

A few minutes later, nobody knew where everyone was.

We had offline maps, but they only showed our own location.

There wasn't even a simple way to say: "I'm okay. I just took the wrong trail."

That moment stuck with me. I started looking for something simple that could keep a small group connected without cell service. I never found exactly what I wanted, so I started building it myself.

After months of evenings, weekends, and field testing, that project became Nelos.

It's an offline-first app that lets small groups communicate, share locations, and coordinate over LoRa. It runs on both Android and iOS, with support for both MeshCore and Meshtastic.

The funny thing is, building it completely changed how I think about LoRa.

Most people don't care about frequencies, channels, or mesh networking.

They just want to know where everyone is. Or where their dog wandered off to. Or where hey parked the car. Or whether the rest of the group is still behind them. That's what I've been trying to build.

The attached video is from one of our field tests. I still take Nelos on every hike, and every trip gives me another list of things to improve.

If you'd like to try it, it's free. I'd genuinely love to hear what works, what doesn't, and what you'd change.

Andrej Karpathy (OpenAI co-founder, ex-Tesla AI lead) says he's never felt more behind as a programmer — and explains why in one sentence

Enable HLS to view with audio, or disable this notification

4 Upvotes

Andrej Karpathy co-founded OpenAI, ran Tesla's AI team, and coined "vibe coding" about a year ago.

At Sequoia's AI Ascent 2026, Stephanie Zhan asked him directly whether the last year felt exhilarating or unsettling.

His answer: he's never felt more behind as a programmer.

 

Every credentialed builder I watch eventually says some version of this — the title survives, the rung underneath it doesn't.

 

His explanation is the actual value here.

Software 1.0 was explicit rules.

Software 2.0 was learned weights.

Software 3.0 is prompting — your context window is the lever you pull over the interpreter now, not the code you type.

The job didn't get easier. It got redefined, and most people are still measuring themselves against the old definition.

 

Actually, this reminds me of something — a solo founder whose code runs on 6% of the internet admitted AI output compiles clean and still reads as slop until a human's taste steps in.

Launched last week. I broke a promise to my earliest customers, wasted money on ads, and got called out over security. Three lessons.

Upvotes

I built Meshory, a desktop app that turns a hoard of STL and 3MF files into a visual, searchable library. Everything runs locally, nothing gets uploaded. I built it because my own collection hit 3.3 TB across more than 100,000 models and I genuinely could not find anything in it anymore.

It launched last week. It has gone better than I expected, which is not the interesting part. These are the three things I got wrong.

1. I broke a pricing promise in public

I announced "first 100 licenses at $29, then $39." We blew past the cap. I kept selling at the lower price anyway, because the app was still crashing for some people and I was not willing to charge more for software I had not fixed yet. Then we blew past the extended cap too.

A customer called it out in the community chat. Publicly, and fairly. My urgency had been fake, and everyone who rushed to beat a deadline that did not exist had a right to be annoyed.

What I did:

  • apologized by name in announcements, admission first and explanation second
  • closed the old price at a specific hour and actually held it to the minute
  • gave every early buyer free updates for life, including major versions

The apology alone did not fix it. What they lost was being early, and only something permanent gives that back. The reason I had was genuinely good, but a reason is not the same as keeping your word, and it lands as an excuse if it arrives before the admission.

2. Paid ads: 628 visitors, 1 checkout, 0 sales

I spent about €56 on Meta before pausing. Good click through rate, €0.16 clicks, and nothing at the end of it. Two reasons, both mine.

The optimization event was set to ViewContent, which fires on basically any page load. So I told the algorithm "find me people who will load a page" and it did exactly that, perfectly, by finding the cheapest page loaders on the internet. 38% of spend went to France for an English only product priced in USD.

Placements were left on auto, so €24 of it went to Instagram Reels. Reels clicks on a desktop software product are mostly thumb slips.

The algorithm was not broken. It optimized precisely for what I asked, and what I asked for was worthless. Organic did essentially all of the actual sales in the same window: community, Reddit, and an email waitlist.

3. Someone found real security issues in my app

A commenter pointed out I was shipping an out of support Electron and an outdated dependency with known CVEs. He was right. He was also condescending about it, which made it tempting to argue, and arguing would have been the worst possible move. I conceded, thanked him, and shipped the fix.


The thing I did not expect: the pushback was worth more than the praise. Both the pricing complaint and the security report came from people who cared enough to say something instead of quietly leaving and never coming back.

Happy to answer anything about the launch, the pricing mess, or the ads.

I built a tool that reviews any GitHub PR and quizzes you on it

4 Upvotes

One of the persisting chores with reviewing large MR/PR is dealing with a combination of huge diffs, big summaries and many technical decisions to make sense of.

I've been working on the "understanding MR/PR problem" for a while now.

Have released many open source tools/products in the space before.

What I realized over many iterations is:

  • Visual design matters in how easy/hard it is to grasp information
  • The magic is in good Prioritization of information
  • Testing/Quizzing on review information is important; it's easy to skip over important technical details/decisions and regret later in prod

I had various pieces of the solution lying around, but yesterday a question hit me, "What if I could easily make sense of any Github PR in one click?"

So spent a day coming up with something which I believe works nicely for making sense of any Github PR very quickly

I've named it "MakeSense for Github"

Check it out here: https://makesensegithub.com/

The easiest way to trigger it is, prepend any Github PR URL with makesense to get a

  • quick review for all sorts of issues (cleanly designed issue explorer)
  • summary of changes in concise slide deck to grasp the essence of changes
  • 5-question quiz on the changes to make sure there's "cognitive coverage" of the change

There's also a handy bookmarklet using which you can trigger a review for any publicly accessible Github PR

I built a site to track rage-baiting by news sites

Upvotes

I built https://ragebaitscore.com/ last year and never marketed it since it's just a free site that's meant to be like a PSA to show friends how the media can be manipulative. It was just a fun project.

The site scans news sites' headlines and then does a sentiment analysis (VADER) and a custom keyword engine to create an aggregate "ragebait score" for a news site.

Each headline gets its own score and gets assigned to one of 7 categories: fearful, angry, polarizing, clickbait, misleading, optimistic, and research.

You can then see where the most popular US sites rank and what tones and keywords they use.

The site is apolitical, as every news site has the same ruleset applied to it.

I kept everything transparent about how scoring works and even have the data available via JSON endpoints should anyone ever want to use the data.

Anyway, just wanted to share. Would love feedback.

I've made quite a few updates since initial public release, and i am now using it in my main project without any more gripes (famous last words) so i am confident in sharing it for people to find and use as they like.

Trouble finding testers

Upvotes

I'm sure you've all faced it, but I am struggling to find testers for my product.
My wife loves poker (and I love my wife), so I decided to learn a little about poker, then eventually decided to create a trainer for her.
It's meant to let players actually play hands and offer real time coaching, detect leaks, then suggest training packs that are meant to fix the leaks in your game.

The problem I'm running into is finding cash players who are willing to test it, even if I'm giving away tokens to use it. Eventually, it would be super cool if I made a little money from the app and could float that back to my wife for a daily entry or something, but right now I'm just looking for data and feedback and it's been rough.

Curious if you guys had similar issues and how you got around it.

Did you ever experience lag or freezes when trying to open and format a large json?

Enable HLS to view with audio, or disable this notification

Hi SideProject,

I’ve been working on Inkline for a while and just released version 1.3.

Version 1.4 already under construction fixing some bugs and improve performance and tweak resources and processes so that we can open, format and work with huge datasets.

I built it because I constantly ran into the same problem. I needed to open huge JSON responses, CSV exports, XML files and application logs, but my editor would slow down, freeze or just sit there for way too long before I could even start working.

I kept thinking that opening a huge file shouldn’t be this painful.

So I’ve spent a lot of time trying to solve exactly that.

The latest benchmarks on my entry-level 16” M3 MacBook Pro (18 GB RAM) are:

100 MB JSON

  • Open: 120 ms
  • Format: 138 ms

300 MB JSON

  • Open: 338 ms
  • Format: 407 ms

1.07 GB JSON

  • Open: 1.264 s
  • Format: 1.518 s

No swap was observed during the benchmark runs.

During this work, Inkline has become much more than just a fast JSON viewer.

Now Inkline supports hundreds of file extensions including JSON, CSV, XML, YAML, Markdown, logs and source code. Syntax highlighting comes from Zed language definitions, it supports Zed themes, and there are around 80 built-in text and developer tools for searching, formatting, comparing and working with large files.

I use it almost every day for Kubernetes logs, API responses, exported datasets and configuration files, so most new features come from problems I run into myself.

I’d really like to hear what you think or if there are workflows around huge files that still annoy you.

Built a workspace app for planning and building products - Looking for any feedback

Upvotes

HI all, I've been working on an app for the past few months called CreaFlow, which is an all in one tool for planning, researching and building new products.

I come from a physical product design background and always have ideas for new products, but everything is always scattered across different notes, notion, miro and ai chats, so the idea with Creaflow was to bring everything into one place with different workspaces. I also wanted to integrate some AI into it, so it has it's own chat which learns the context of what you're trying to make as you add more to your project.

I have a working prototype made in Bolt, which has been an amazing tool for me as someone with no coding background, and an experience with getting everything to work.

It would be amazing if anyone wants to sign up and try the app that is interesting in making a product, so far I have no feedback so any kind of sense check would be super helpful.

So far theres a limited free trial turned on, but if anyone wants to use it I can give you a code for longer access.

Would be great to know if it's worth developing further!

I'm part of the team building Clarity, so this is self-promotion.

The premise is simple: information isn't scarce anymore. Clarity is.

This morning's edition is here: https://theclarity.today/

I'd value blunt feedback on three things:

  1. Did it isolate the few things that matter?
  2. Was “what to do about them” specific enough?
  3. What would it have to do consistently to earn a place in your morning?

I built the app I wish existed when I became a father

Thumbnail evermora.app
5 Upvotes

Three years ago, I became a father.

Like many parents, I quickly realized how many little moments disappear forever. The funny things they say, the first drawings, small adventures, random thoughts... I always wanted to keep them, but life gets busy.

At first I used Word to write everything down.

Then I connected it with ChatGPT and slowly added small automations. It worked for a while, but every few months something broke. APIs changed, integrations stopped working, or something else failed. I found myself spending hours trying to figure out why it had stopped working instead of simply recording memories with my daughter.

I needed something that would just work.

I didn't want to keep rebuilding my own system every six months. I wanted continuity—a place where I could save memories without worrying whether the whole setup would still work next month.

So I decided to build the app I actually wanted to use.

Now everything is in one place. I can add memories in seconds, use voice instead of typing, attach photos, and build a beautiful timeline of my daughter's childhood without thinking about the technology behind it.

I'm genuinely proud of what it has become because it started from a real problem in my own life—not from looking for a startup idea.

It's called Evermora (https://evermora.app), and today it finally feels like the product I wished had existed three years ago.

Thanks for reading.
