LegacyDoc AI

What is LegacyDoc AI?

LegacyDoc AI is a VS Code extension from RomantiCode that documents code you did not write or no longer understand. You select a file, folder or module in your workspace and it generates function-level JSDoc, Markdown handoff docs, Mermaid diagrams of dependencies and call paths, and a context pack you can give to Claude Code, Cursor, Codex or Gemini. It is built for legacy projects, vibe-coded prototypes and AI-generated apps that need a map before cleanup, a launch review or a handoff to a freelancer. The extension uses your own API key, so you choose Claude, GPT, Gemini, Grok or any OpenAI-compatible endpoint, and RomantiCode does not store your code. It documents and flags risk rather than rewriting logic for you. A free plan allows 5 generations per day, and the Pro license is a one-time $29 payment.

Use cases

• Document an inherited codebase
• Generate JSDoc for undocumented functions
• Draw Mermaid diagrams of module structure
• Prepare context packs for coding agents
• Map an AI-built app before cleanup
• Gather material for a cleanup quote
• Review an app before launch

Who it's for

• Developers
• Founders with AI-built apps
• Freelance cleanup specialists
• Engineering teams

Why use LegacyDoc AI

• You get a readable architecture map and docs before anyone changes production code, which makes cleanup quotes and reviews easier to scope.
• Context packs spare you from re-explaining the project every time you start a Claude Code, Cursor or Codex session.
• Because you bring your own key, you pick the model provider and keep control over where your code is sent.
• Pro is a single one-time $29 payment rather than a recurring subscription.
• The free plan needs no credit card, so you can test it on a small project first.

2. Open the sidebar and select the file, folder or module you want to document or audit.
3. Output JSDoc comments, Markdown docs, Mermaid diagrams and a context pack, all built from the same scope.
4. Review the output, keep it in your repo and hand the context pack to your coding agent or developer.
5. For Pro, buy the license through Creem, then paste the emailed key into the extension settings.
