AI Helper — Error Tutor

A small AI model that runs entirely in your browser and explains your code errors in plain language. Set it up once; it then works across every coding lesson — offline, no servers, no keys.

Who it's for

Any learner who wants a plain-language hint when their code errors — especially beginners.

What you'll learn

  • Get a plain-language explanation of any code error, on demand
  • A nudge toward the fix — never the full solution (your lessons' Hints do that)
  • Runs 100% in your browser: your code never leaves your device
  • Choose a model size that fits your device — Light, Recommended, or Quality
