AI Docstring Generator

Function
What this tool does
Reads a function and writes an accurate documentation block in the correct format for the language: JSDoc, PHPDoc, Python (Google / NumPy style), Rustdoc, or GoDoc. Includes parameters, return type, thrown exceptions, and a usage example.
Who it's for: Developers who value documentation but don't want to write it by hand, and teams enforcing doc coverage in CI.
When to use
- •Add missing docstrings to a legacy library before publishing.
- •Onboard a new team member by documenting core internal APIs.
- •Generate starter JSDoc for a TypeScript utility library.
- •Produce public-facing API docs automatically from function signatures.
How it works
- 1Pick the target language.
- 2Paste the function source code.
- 3AI infers parameter types (when not annotated), return, and possible throws.
- 4Copy the docstring + example directly above your function.
Tips
- •Include type annotations in the source - AI produces sharper documentation.
- •Always review generated examples for accuracy before committing.
- •Use the throws section as a prompt to add explicit error handling.
