Automatic code documentation
Connect a repository and generate a hierarchical documentation tree from source code instead of starting from blank pages or MDX files.
DocuWriter
ClaimDocuWriter is an AI code documentation tool that generates code docs, API docs, and UML diagrams from a connected repository, keeping docs aligned as code changes.
What DocuWriter does
DocuWriter is an AI code documentation tool that connects to a repository and generates documentation from the source code. The product focuses on three outputs: code documentation, API documentation, and UML diagrams, with the goal of turning an existing codebase into a structured documentation set without manual authoring from scratch.
The source describes a workflow in which DocuWriter reads the codebase with AST parsing and a code-aware retrieval pipeline, then keeps documentation synchronized as the repository changes. It supports GitHub, GitLab, Bitbucket, and Azure DevOps, and includes reviewable update suggestions through its Autopilot agent.
Features
API documentation
Generate Swagger/OpenAPI-style API docs from API code, including references for endpoints and request patterns.
UML diagram generation
Create class, sequence, and component diagrams from the codebase, with Mermaid and PlantUML mentioned in the source.
Autopilot AI Agent
Watch connected repositories for changes and open reviewable update suggestions when code evolves, so docs stay aligned with the code.
Publish and export options
Publish documentation to a private team space or a public-facing site, and export to Markdown, Word, PDF, Confluence, or Git.
AI workspace and MCP access
Use spaces for documentation management and connect to ChatGPT, Claude, or Cursor through MCP, with n8n integration also mentioned on the features page.
Use cases
Inherited codebases
Document a large or inherited codebase when the team has little or no existing documentation and needs a structured starting point from source.
Documentation drift
Keep reference material current when frequent commits or pull requests make manual documentation hard to maintain.
Engineering onboarding
Help new engineers find architecture, API, and module information without relying on tribal knowledge or repeated Slack questions.
Compliance and review work
Produce code, API, and UML documentation for audits, due diligence, or partner reviews that need organized technical material.
Handoffs and migrations
Generate and export handoff packets for migrations, acquisitions, client deliveries, or internal transfers between teams.
Pros and Cons
Pros
- Generates documentation from raw source code, so it can be used even when no existing docs are in place.
- Covers three core documentation outputs: code docs, API docs, and UML diagrams.
- Keeps documentation in sync with repository changes through the Autopilot review workflow.
- Supports multiple repository platforms, including GitHub, GitLab, Bitbucket, and Azure DevOps.
- Offers export and publishing options for team spaces, public sites, and common formats such as Markdown, Word, PDF, Confluence, and Git.
Cons
- Pricing and plan boundaries are only partially documented in the provided source, so buyers may need to confirm current limits and billing details on the pricing page.
- Some integrations are described at a high level, but the source does not fully document workflow hooks or platform-specific behavior for every supported repository host.
FAQ
How does DocuWriter work?
DocuWriter connects to a repository, analyzes the codebase, and generates documentation artifacts from the source. The source describes a three-step flow: connect your repo, let DocuWriter read the code, then review, publish, and keep the documentation fresh.
What kinds of documentation can it generate?
The source says DocuWriter produces code documentation, API documentation, and UML diagrams. The features page also describes Swagger/OpenAPI output and UML class, sequence, and component diagrams.
Which repository platforms does it connect to?
DocuWriter supports GitHub, GitLab, Bitbucket, and Azure DevOps. The source mentions GitLab self-hosted support and connection via OAuth or personal access token.
Is DocuWriter free, or does it require a paid plan?
The pricing page lists paid plans and states that pricing is per generation rather than per seat. It also mentions a Starter plan, yearly billing with four free months, and a Custom plan for SSO, self-hosted runtime, or custom volume.
Can documentation be shared or exported?
The source says output can be published to a private team space or a public-facing site, and docs can be exported to Markdown, Word, PDF, Confluence, or Git. It also says each space publishes as an MCP server.
