AI Agents

Bad docs break your AI agents

Claude Code, Cursor, and Copilot read your docs to reason about your code. Stale docs cause wrong suggestions and hallucinations. Pith keeps them current.

  • Always-fresh context. Docs update on every PR approval. Agents always read current architecture and API signatures.
  • No manual upkeep. Pith runs automatically. No maintenance required.

Code Intelligence

Powered by deep code understanding

Reads your full codebase, not just the diff. Every type, export, and dependency verified before it gets documented.

  • Semantic diff analysis. What changed and what it affects.
  • Cross-file dependency mapping. Every impacted doc section, updated.
  • AST-verified signatures. From the AST, not inferred.
  • Incremental updates. Manual edits stay intact.

Use it your way

PR approval, schedule, CI step, or API. Pick what fits your workflow.

Trigger on PR approval

Install the GitHub App. When a reviewer approves, Pith generates docs and commits them to the branch - no YAML, no extra steps.

  • Zero configuration after the 2-minute install
  • Docs committed directly to the PR branch
  • Merge code and docs in a single review
  • Works with GitHub and GitLab

Pith listens to the webhook automatically, nothing to configure in CI.
