Docster
Your code already knows.
Let it write the docs.
Docster analyzes your repository and generates accurate README, API reference, CHANGELOG and CONTRIBUTING docs — delivered as a Pull Request you just review and merge.
Free: 1 README/day. No credit card to start.
See it in action
From a repo with no docs to a merged Pull Request — in under a minute.
Docs are always the thing you put off
- 📝 Writing a README is never as fun as writing code.
- 🕒 Once written, it drifts out of date with every change.
- 🌐 Formatting and English get in the way — so it stays a one-liner.
And a thin README means fewer stars, fewer contributors, fewer users.
Without Docster vs. with it
| 📦 Without Docster | ✅ With Docster | |
|---|---|---|
| README | A one-liner, or empty | A real, code-grounded README in minutes — as a PR |
| Staying current | Drifts out of date with every change | Regenerates on every push via GitHub Actions |
| English & formatting | Keeps it stuck at a one-liner | Generate in English or Japanese |
| Trust in AI | Fear of invented, broken commands | Unverifiable parts flagged (TBD) — no hallucinations |
What you get
- ✅ Four doc types — README, API reference, CHANGELOG and CONTRIBUTING.
- ✅ Grounded in real code — generated from your actual files. Anything it can't verify is flagged (TBD) instead of hallucinated.
- ✅ Delivered as a PR — no surprise overwrites. Diff it, edit it, merge it.
- ✅ English or Japanese output, your choice.
- ✅ GitHub Actions ready — an included template regenerates docs on every push.
Keep your docs up to date — automatically
On Pro, a GitHub Actions template regenerates your README on every push and opens a single Pull Request to review. Set it up from your dashboard in a minute — your plan limit is enforced server-side.
Why not just Copilot?
- Copilot is editor-side autocomplete. Docster analyzes your entire repository and ships a full doc as a single Pull Request.
- It doesn't lie: uncertain sections are flagged, not invented — no commands that don't exist.
- It's not just READMEs — API reference, CHANGELOG, CONTRIBUTING too.

FAQ
- Private repos?
- Yes — GitHub OAuth uses the repo scope. Your code is read only during generation and never stored.
- How accurate is it?
- Grounded in real code. Anything it can't verify is flagged (TBD).
- What about my existing files?
- Never overwritten — changes come as a PR. You decide whether to merge.
- Can it stay up to date automatically?
- Yes — drop the included GitHub Actions template into your workflow.
