Which languages are supported?

TypeScript, JavaScript, Python, and other common languages; results are best for mainstream syntax.

Yes. It is free and open source. AI review uses free providers by default, with optional bring-your-own-key.

Does my code get uploaded?

The AI review sends the snippet to the provider you select. Avoid pasting secrets or proprietary code you cannot share.

Will it rewrite my code?

It suggests refactors and can provide a refactored snippet, but it will not rewrite working code with low complexity.

Can it replace a human review?

No. It catches common issues fast, but human review is still needed for design and domain logic.

About this tool

The Code Review Assistant analyzes a code snippet for bugs, anti-patterns, and code smells, and suggests concrete refactors. Paste TypeScript, JavaScript, Python, or other code to get feedback by line, a complexity score, and a summary. It is a fast second pair of eyes before you open a pull request.

How to use it

Paste your code. Drop in the snippet you want reviewed, optionally with a language hint.
Run the review. Get issues by line, a complexity score, and a plain-language summary.
Apply the suggestions. Review the recommended refactors and adopt what fits.
Re-check. Paste the revised code to confirm the issues are resolved.
