Hey HN,

I wanted to share something I’ve been quietly building while navigating a very real challenge: I’m $25,000 in personal debt.

Instead of applying for jobs, I decided to build my way out—lean, fast, and solo.

One of the biggest bottlenecks I face when launching ideas is messaging. I’d open Notion or Excalidraw and just freeze. The ideas were there, but the clarity wasn’t. I always ended up spending hours thinking about my audience, brand values, voice, etc.—before I even started coding.

So I built RuleOf3.ai.

It’s a small tool that helps founders generate a full branding strategy—anchored to their purpose and audience—using a psychology principle called the “Rule of 3.” (You’ve probably felt this: 3 little pigs, “Just do it”, etc.)

It doesn’t replace strategists, but it gets me unblocked in under a minute.

I use it now for every micro SaaS and hackathon project I ship. It now became my "idea bank" for future builds.

I'm sharing this here not as a plug, but as a build-in-public checkpoint.

If you’ve ever been in that “blank canvas” phase or stuck at the brand/messaging layer of your project, this might help.

Would love feedback from other founders here—especially if you’ve ever tried building your way out of a hole like this.

Thanks for reading.

Learning Chinese characters is unreasonably hard and is arguably the main reason why most people give up on the language. The existing apps mostly just show you a character and ask you to “remember” these random-looking complex shapes.

Frustrated with this during my own learning journey, I decided to build Hanly. The core idea: there is deep tree-like structure to Chinese characters, and Hanly teaches them by making you climb up this hierarchy, so that at every step you either learn a very basic building block or combine already known building blocks. This approach makes learning feel more like playing with LEGOs rather than memorizing random shapes.

I left a link for iOS but the app is also available on Android (currently completely free on both platforms): https://play.google.com/store/apps/details?id=app.hanly.chin...

It’s the first app I ever built and any feedback is very appreciated!

We created Thumbgen, a web-based platform that uses AI to generate high-performance thumbnails for video content.

The idea started from a simple observation: thumbnails directly influence click-through rates, yet most creators spend disproportionate time designing them manually or rely on generic tools.

Thumbgen uses prompt-based image generation models (via OpenAI and Replicate) combined with template intelligence and real-time feedback to craft thumbnails optimized for visibility and engagement. The system is designed for creators who value speed, precision, and visual consistency.

Built with Next.js and Tailwind CSS, Thumbgen prioritizes performance and simplicity. There is no required design knowledge. Users simply describe what they want, and the system handles the rest.

Currently at 2,000+ concurrent users and growing, the platform is still evolving. We are exploring native YouTube integrations, A/B testing capabilities, and localized thumbnail adaptation.

Would appreciate feedback from the HN community regarding performance, infrastructure decisions, or use cases we might be overlooking.

I've started building Neural Foundations, a Python library to explore the first principles of neural networks by constructing them from atomic primitives (cells, layers, activations, etc.). Inspired by the Asimov Institute's "Neural Network Zoo".

This is an early-stage playground aimed at those who really want to explore and internalize NN fundamentals by diving into and hacking the foundational_nn and architecture_nn packages, which are then used to build models in models_nn.

While you won't find Transformer architectures here yet, the library essentially provides all the building blocks to (eventually) create everything from the Neural Network Zoo infographic.

I'm also keen on visualizing simpler architectures (beyond just the TUI), which should be a relatively easy entry point for contributions. So, if you're interested in getting involved, contributions to the visualization (or any other!) module are very welcome!

I'm also open to discussion about the project structure, ways in which it might be run, potential use cases, and any other ideas you might have. Let's build this together!

Check out the code and interactive TUI for experimentation: https://github.com/ndjuric/neural_foundations/tree/main

Note: it's in the earliest possible development stage :)
