AI tutor add-on (Lifetime only) — $4.99/month

What the AI tutor is — and isn't
The tutor gives explanations and hints for the task you're working on, using your saved work. It's capped at 100 requests per calendar month (UTC), with limits on request length. It never grades your work, changes scores, or gives tax or legal advice, and it's switched off during timed assessments. It is not unlimited.
