LegacyDoc AI

LegacyDoc AI, made by RomantiCode, is a VS Code extension that generates documentation and context for legacy, AI-generated, or inherited codebases, helping developers understand and prepare code before cleanup, audit, or handoff. It auto-generates JSDoc and inline comments that preserve existing code style, standalone Markdown documentation files with signatures, parameters, and usage examples, and Mermaid diagrams mapping module dependencies and call flows as renderable architecture diagrams. AI-ready context packs export structured project briefs for Claude Code, Cursor, Codex, or Gemini, and cleanup readiness notes identify risky areas and missing documentation before refactoring. It supports multi-model BYOK (bring your own key) for Claude, GPT, Gemini, Grok, or custom OpenAI-compatible endpoints. Pricing includes a Free tier (5 generations/day, all core features) and Pro ($29 one-time, unlimited generations, batch processing, up to 3 devices).
