RepoCarta: AI that writes and maintains your GitHub repo docs

Hi Product Hunt! 👋 I built RepoCarta because documentation always rots — it's written once and never kept up with the code. RepoCarta connects to a GitHub repo and: • Auto-generates docs (architecture, API spec, ER diagrams, setup guides) • Keeps them current on every push / merged PR (incremental, cost-aware) • Answers questions about the codebase in natural language, with source citations from your actual files • Lets you share per-project with your team It's especially useful for onboarding new engineers and for repos where the "tribal knowledge" lives only in people's heads. There's a 14-day trial (no card required). I'd love your feedback — especially on what doc types you'd want generated next. Thanks for checking it out! 🙏
