AI Hallucination Spotter

Stop trusting AI code blindly. Catch fake imports, wrong functions, and impossible logic before you waste time debugging.

The Problem

AI assistants like ChatGPT, Claude, and Copilot are amazing—until they lie to you. They confidently generate code with:

Fake imports that don't exist
Made-up function names that look real
Wrong arguments in the wrong order
Deprecated syntax from old language versions
Impossible logic that will never work

You paste the code, run it, and... error. Then you spend 20 minutes figuring out what the AI got wrong.

The Solution

The AI Hallucination Spotter runs fast static checks on AI-generated code and highlights likely hallucinations before you waste time.

🔍 What It Checks

Python: Fake methods like list.push(), wrong imports like os.exists(), Python 2 syntax
JavaScript: Typos like fs.existSync, non-existent methods like .contains(), Python-style booleans
Java & Go (Beta): Common AI mistakes in these languages

Real Example: Python Hallucination

AI generates this code:

import json
import os

def process_data(file_path):
    data = json.load(file_path)  # ERROR!
    results = []
    results.push(data['value'])  # ERROR!
    
    if os.exists('log.txt'):  # ERROR!
        print("Log found")

The AI Hallucination Spotter instantly highlights 3 errors:

json.load() expects a file object, not a string path
Python lists use .append(), not .push()
os.exists doesn't exist—it's os.path.exists

Real Example: JavaScript Hallucination

const fs = require('fs');

function saveData(data) {
    if (fs.existSync('./data.json')) {  # ERROR!
        console.log('File exists');
    }
    
    const items = ['a', 'b', 'c'];
    items.remove('b');  # ERROR!
}

Issues detected:

fs.existSync should be fs.existsSync (with an 's')
Arrays don't have a .remove() method—use .splice() or .filter()

How It Works

⚡ Client-Side & Fast

All checks run in your browser using pattern matching and common hallucination databases. No data is sent to servers. Results appear in under 2 seconds.

🎯 Trust But Verify

AI is powerful, but it's not perfect. This tool acts as a quick sanity check before you run code from ChatGPT, Copilot, or Claude.

Who Uses This

Solo devs copying code from ChatGPT/Claude
Teams reviewing PRs with AI contributions
Anyone who's been burned by AI hallucinations before

What It's NOT

This tool is not:

A full linter replacement (use Pylint, ESLint, etc. for that)
A code runner (it never executes your code)
Perfect (it catches common mistakes, not semantic bugs)
