AI Code Smell Detector

Paste code above to analyze

Detects hallucinated imports, over-abstraction, verbose error handling, AI tells, security smells, and redundancy patterns across JavaScript, TypeScript, Python, Go, Rust, and Java.

What This Tool Does

AI Code Smell Detector is built for deterministic developer and agent workflows.

Detect AI-generated code anti-patterns — hallucinated imports, over-abstraction, verbose error handling, and more. Instant browser-based analysis, fully private.

Use How to Use for execution steps and FAQ for constraints, policies, and edge cases.

How to Use AI Code Smell Detector

  1. 1

    Paste your code

    Enter or paste any code snippet into the input area. The tool auto-detects the programming language from syntax patterns (JavaScript, TypeScript, Python, Go, Rust, or Java).

  2. 2

    Review detected smells

    The analysis runs automatically and displays findings grouped by category — hallucinated imports, over-abstraction, verbose error handling, AI tells, security smells, and redundancy — each with a severity badge.

  3. 3

    Read the overall score

    Check the overall code quality score (0-100). Scores above 80 indicate clean code, 50-80 suggests some AI-generated patterns to clean up, and below 50 flags significant issues.

  4. 4

    Copy the report

    Click Copy Report to get a markdown summary of all findings with line references and fix suggestions, ready to paste into a PR comment or code review.

Frequently Asked Questions

What is AI Code Smell Detector?
AI Code Smell Detector analyzes code for anti-patterns commonly introduced by AI code generation tools — hallucinated imports, over-abstraction, verbose error handling, redundant logic, and AI-specific tells like numbered step comments.
How does detection work without an AI model?
The tool uses 30+ heuristic pattern matchers (regex and structural analysis) to identify known AI code smells. No LLM API calls are made — all analysis happens deterministically in your browser.
Is AI Code Smell Detector free?
Yes. Completely free with no account or sign-up required.
Does it send my code to a server?
No. All analysis happens entirely in your browser. Your code never leaves your device.
What languages are supported?
JavaScript, TypeScript, Python, Go, Rust, and Java. The tool auto-detects the language from syntax patterns.
