Implit

Stop AI hallucinations before they break your code

"AI wrote code with fake packages. Implit caught them in 0.3 seconds."

Quick Start • Features • Why Implit? • Examples

😱 The Problem

// AI generates this code...
import { awesomeAuth } from 'super-auth-lib';  // ❌ DOESN'T EXIST
import { fetchUser } from './api/users';       // ❌ NO export named fetchUser
import { login } from 'magic-auth';            // ❌ TYPO - should be 'magic-auth-lib'

// You run npm install... 💥 BROKEN BUILD

Every developer using AI has experienced this:

• ❌ AI invents npm packages that don't exist
• ❌ AI guesses wrong local import paths
• ❌ Security risk: hackers can register fake packages
• ❌ Hours wasted debugging phantom dependencies

---

✨ The Solution

Implit scans your AI-generated code and validates every import BEFORE you run it.

npx @neurall.build/implit check generated-code.ts

🔍 Checking generated-code.ts...

✓ react - Package exists on npm
✓ lodash - Package exists on npm
✗ super-auth-lib - Package NOT FOUND on npm registry
✗ ./api/users - No export named 'fetchUser' (available: getUser, deleteUser)
✗ magic-auth - Package NOT FOUND (did you mean: magic-auth-lib?)

❌ Found 3 hallucinated imports!

---

🚀 Quick Start

Zero Config (Recommended)

# Check any file instantly - no installation needed
npx @neurall.build/implit check your-file.ts

Global Install

# Install globally for frequent use
npm install -g @neurall.build/implit

# Then run anywhere
implit check your-file.ts

Generate Fix Prompt for AI

# Get a ready-to-paste prompt to feed back to your AI
npx @neurall.build/implit check your-file.ts --fix

Output:

📋 Fix prompt (ready to paste):

Your generated code has invalid imports:

1. "super-auth-lib" does not exist on npm.
2. "./api/users" does not export "fetchUser". Available exports: getUser, deleteUser.
3. "magic-auth" does not exist. Did you mean "magic-auth-lib"?

Please fix these imports and regenerate the code.
