Show HN: Fata – Spaced repetition to fight skill rot from AI coding

Hacker News Top Products

Summary

Fata is a mobile-first learning platform that uses spaced repetition to help developers sharpen their coding skills, especially when relying on AI coding agents.

Hi HN, I&#x27;m Djoumé. I&#x27;ve been a developer for over 20 years, and like a lot of you I&#x27;ve been coding almost exclusively through an agent in the past few months.<p>It&#x27;s been amazing to vibe code prototypes in any stack, but when it comes to building something reliable&#x2F;scalable, I couldn&#x27;t effectively guide the agent unless I knew the technology. And the scariest part is that I&#x27;m seeing a lot of my technical skills decreasing due to AI coding.<p>Reflecting on my journey, I also worry about how the new &quot;AI native&quot; generation of software developer is going to acquire technical depth.<p>So I built fata.dev: short daily spaced-repetition sessions for programming skills (Rust, CSS, React, Python, TypeScript, Architecture).<p>You can try it in the browser with no signup: <a href="https:&#x2F;&#x2F;fata.app&#x2F;courses" rel="nofollow">https:&#x2F;&#x2F;fata.app&#x2F;courses</a><p>It&#x27;s an offline-first mobile app built with Capacitor, RxDB and Firebase. The first courses were painfully written by hand, but most content is now AI-generated. It takes about 3000 LLM calls to generate a course, and every code samples goes through compilation, linting, unit testing, AI and a final manual review.<p>Would very much appreciate any feedback on the product &amp; website, what works and what could be better. Thanks!
