Product overview

AI can write code fast. Check AI Code helps you trust it before shipping.

Check AI Code catches practical bugs, security risks, and AI-generated code mistakes in small scripts, components, API handlers, and multi-file snippets.

3 practical risks

Static rules + AI-focused checks

CRITICAL

Async forEach is not awaited before returning.

WARNING

Input is passed directly into a database write.

INFO

Review framework and runtime assumptions.

The problem

AI code looks plausible

It can invent APIs, skip awaits, miss runtime edge cases, or use examples from the wrong framework version.

Linters are not enough

Format and style checks are useful, but they often miss practical semantic mistakes in generated code.

Manual review is slow

For small teams and independent builders, every pull request cannot wait for a full human review cycle.

What it can check

AI hallucinations

Fake methods, suspicious package usage, non-existent APIs, and migration-era examples.

Security patterns

Secrets, unsafe deserialization, command injection, path traversal, and dangerous defaults.

Runtime bugs

Async misuse, missing timeouts, mutable defaults, swallowed errors, and production-footgun patterns.

Framework drift

Deprecated APIs, version mismatch patterns, and code copied from stale examples.

Static + enhanced review

Fast rule checks first; Pro can add deeper LLM-enhanced explanation when appropriate.

Privacy-conscious option

Privacy Mode skips LLM enhancement while still running static checks.

How it differs from other tools

Check AI Code is not trying to replace mature tools like dedicated SAST platforms, dependency scanners, or full security audits. It is designed as a fast first pass for AI-assisted development.

Traditional linters

Great for style and local conventions.

Check AI Code focuses more on practical mistakes and AI-generated code failure modes.

Security scanners

Strong for known vulnerability classes and enterprise workflows.

Check AI Code is lighter-weight and easier to run before you ship a small change.

Manual code review

Best for product intent and business logic.

Check AI Code gives a quick risk screen before a human spends attention.

Who it is for

Developers using Cursor, Claude Code, Copilot, ChatGPT, or other AI coding tools

Independent builders shipping small apps, automations, scripts, and API endpoints

Small teams that want a fast sanity check before review or deployment

Anyone reviewing code they did not fully write by hand

Honest limits

It cannot guarantee every bug, vulnerability, or business-logic mistake will be found.

It does not replace tests, type checks, human review, dependency scanning, or a formal security audit.

Results are risk signals. You still decide what matters for your codebase and users.

Use it as the review before the review.

Paste code, upload a file, or try a small AI-generated snippet. You will see quickly whether the tool catches issues that would have been easy to miss.
