I Built a Free GitHub App That Auto-Updates Your Docs on Every Push
Your README hasn't been updated in months. Your CHANGELOG doesn't exist. Your API docs say "TODO." Sound familiar?
The Problem
As developers, we're great at shipping features but terrible at keeping docs up to date. It's not that we don't care — it's that there's always something more urgent.
The result? Users struggle to use our projects. Contributors can't onboard. And we spend hours before every release frantically updating docs.
The Solution
I built DocuPilot— a GitHub App that automatically generates and updates your documentation every time you push code. Install once, never think about docs again.
- Install the PushDocs GitHub App on your repo
- Push code as you normally would
- DocuPilot analyzes your changes using AI (Claude API)
- You get a Pull Request with updated documentation
No config files. No CLI tools. No CI/CD pipeline changes.
What It Generates
- README updates— Feature descriptions, usage examples, installation instructions
- CHANGELOG entries— Automatically categorized (Added, Changed, Fixed, etc.)
- API documentation— Endpoint descriptions, parameters, response types
All changes come as PRs, so you stay in full control. Review, edit, merge — just like any other PR.
Why Not Use an Existing Tool?
| Tool | Price | Target |
|---|---|---|
| Mintlify | $300+/mo | Enterprise teams |
| ReadMe | Enterprise pricing | Large companies |
| Redocly | Varies | API-only docs |
| DocuPilot | Free — $29/mo | Individual devs & small teams |
Most documentation tools are built for companies with dedicated technical writers. DocuPilot is built for the solo developer who wants their docs to just... stay updated.
Pricing
- Free: $0/mo — 1 repo, README + CHANGELOG
- Starter: $9/mo — 5 repos, README + CHANGELOG
- Pro: $29/mo — Unlimited repos, API docs, custom templates
The free tier is free forever. No trial period. No credit card required.
Tech Stack
For the curious builders:
- Frontend/Backend: Next.js on Vercel
- AI: Claude API (Anthropic) for code analysis and doc generation
- Auth: GitHub OAuth
- Payments: Stripe
- State: Vercel KV (Redis)
- Integration: GitHub App with webhook on push events
