DocuWriter: AI code documentation tool for any codebase
AI Code Documentation Tool
Generate complete AI code documentation for any codebase. In seconds, not months.
DocuWriter is an AI code documentation tool that connects to your repository and generates a full book-style documentation tree from your source code: code documentation, API documentation, and UML diagrams. It keeps everything in sync as your code evolves. No MDX. No prose to maintain. No documentation team required.

DOC Code Documentation
The problem
Most engineering teams have no documentation. Or what they have is three years out of date.
"We inherited a 12-year-old codebase and nobody knows how it works anymore."
– every engineering team ever
"Our docs are so stale that nobody trusts them. We just ask the senior engineer."
– the senior engineer who is tired
"We're onboarding eight new hires next quarter and they can't find anything."
– the head of engineering writing this on a flight
How it works
Three steps. No documentation team required.
01
Connect your repo
GitHub, GitLab (incl. self-hosted), Bitbucket, Azure DevOps. OAuth or PAT. Two clicks.
02
DocuWriter reads your code
We analyze your codebase with AST parsing and a code-aware retrieval pipeline, not an LLM editing prose. The result is a complete, hierarchical documentation tree grounded in your actual source.
03
Review, publish, keep it fresh
Edit anything in our editor. Publish to a private team space or a public-facing site. Autopilot watches your repo and opens reviewable update suggestions every time the code changes.
Use cases
Built for codebases like yours.
The five reasons our customers actually buy.
Inherited an undocumented codebase
"We bought / merged / inherited 12 years of code with no docs."
→ Tree Documentation Generator
Documentation rot
"Our docs were great in 2022. Now nobody trusts them."
→ Autopilot AI Agent
Onboarding new engineers
"New hires spend their first month asking the same questions."
→ Spaces + AI Q&A
Compliance & audits
"The auditor wants architecture, API, and module documentation by Friday."
→ Full-tree + UML + API Documentation
Handoffs & migrations
"We're handing this codebase to a partner / acquirer / new team."
→ Generate, edit, export to Markdown / Word / PDF / Confluence / Git

Autopilot AI Agent
Documentation that maintains itself.
Most documentation tools assume you'll write everything yourself and remember to keep it updated. You won't. Nobody does.
DocuWriter's Autopilot is the AI documentation tool that watches your connected repositories. When code changes (every push, every merged PR) it reviews the diff, identifies which documents are now wrong, and opens a reviewable suggestion. This is real automatic code documentation: Approve, discard, or edit before anything is published.
Notifications go to Slack, Teams, Google Chat, or your custom webhook. Auto-apply rules let you skip review for low-risk doc-only edits. High-confidence suggestions can be applied automatically; sensitive ones always wait for a human.
