Traditional linters check syntax and style rules. CodeScan AI understands the semantic meaning of your code — it can detect business logic vulnerabilities, architectural anti-patterns, and performance issues that linters miss. It combines static analysis with LLM reasoning.
CodeScan AI supports 20+ languages including TypeScript, JavaScript, Python, Go, Java, Rust, PHP, C#, Ruby, Swift, Kotlin, and more. Language support is continuously expanding.
No. Code snippets are processed in memory and never stored on disk or used for model training. Enterprise plans offer self-hosted deployment for complete data sovereignty.
Yes. CodeScan AI integrates with GitHub Actions, GitLab CI, and any CI system via our REST API. Pro plans include native GitHub and GitLab integrations that automatically review every pull request.
CodeScan AI has a 94% precision rate for security findings, meaning very few false positives. It is continuously improved using feedback from thousands of reviews. Critical findings are cross-validated against known vulnerability databases.
