Doctective automatically detects when code changes break your documentation and analyzes every PR to catch stale docs before they ship. It provides automatic PR analysis for stale docs, GitHub comments on affected documentation, and semantic code-to-doc mapping.

Key features include PR impact detection that analyzes every pull request to identify which documentation might become stale based on code changes. The system offers companion PR generation that automatically creates a companion PR with suggested documentation updates when code changes. It also provides LLM doc updates with AI-powered documentation that understands your codebase context and maintains consistent style.

The system works by connecting your GitHub repository, where Doctective analyzes your code and existing documentation to build a semantic map. When code changes occur, Doctective checks which documentation references the modified functions, APIs, or classes. The system then comments on your PR with exactly which docs need updating, allowing you to fix them before the code ships.

Benefits include eliminating outdated documentation that misleads developers and prevents new hires from wasting days on outdated guides. Use cases include catching when refactors invalidate existing references, ensuring API changes are reflected in docs, and identifying which docs are affected by code modifications.

The product is built for modern engineering teams and integrates with GitHub repositories. It supports TypeScript, Python, Java, Go, Rust, SQL and more programming languages, with enterprise-grade security including SOC 2 Type II compliance, end-to-end encryption, GDPR compliance, and self-hosted options.
