Question 1

Is my code sent to a server?

Accepted Answer

No. The AI model (SmolLM2) runs 100% in your browser using WebGPU or WASM. Your code is processed locally and never leaves your device. There is no signup, no upload, and no data collection. This makes it safe for reviewing proprietary or confidential code.

Question 2

What languages are supported?

Accepted Answer

The tool supports JavaScript, TypeScript, Python, Java, C++, C#, Go, Rust, Ruby, PHP, Swift, Kotlin, Scala, SQL, HTML, CSS, Shell, and more. Language detection is automatic, but you can also manually select the language for more accurate analysis.

Question 3

How accurate is the AI code review?

Accepted Answer

The AI model provides a good first-pass review that catches common issues like SQL injection, unused variables, missing error handling, and performance anti-patterns. However, it is not a replacement for human review — always verify the suggestions and use your judgment. The tool is best used as a quick self-check before submitting code for peer review.

Question 4

What types of issues does it find?

Accepted Answer

The tool identifies issues in six categories: Bugs (logic errors, null references, race conditions), Security (injection, XSS, hardcoded credentials), Performance (unnecessary loops, memory leaks, inefficient algorithms), Code Style (naming, formatting, consistency), Best Practices (error handling, design patterns), and Maintainability (complexity, duplication, documentation).

Question 5

Is this code review tool free?

Accepted Answer

Yes, 100% free with no signup, no API key, no usage limits, and no watermark. The AI model runs in your browser, so there are no server costs.
