Frequently asked questions
What is the best AI for documenting existing code?
GitHub Copilot and Cursor generate clear docstrings and comments directly in the editor, line by line or function by function. Sourcegraph Cody is better suited to documenting or explaining an entire codebase.
Can you generate a README automatically with AI?
Yes: Cursor and Windsurf (Codeium) can write a complete README from project structure and code, to review and adjust afterwards.
