LegacyDoc AI
Beta

Document legacy code in minutes—AI-generated docs inside VS Code

A VS Code extension that writes accurate, consistent docs for aging codebases, without leaving your editor.

The Problem for Developers

😩

Documentation is manual and error-prone

Writing docs by hand is slow and inconsistent across modules.

Docs drift when code changes

Keeping docs in sync with evolving legacy code is a constant battle.

🧭

New teammates struggle to understand the code

Onboarding suffers without reliable, up-to-date docs.

💸

Maintenance costs creep up

Time spent updating docs steals time from delivering features.
