AI credits & monthly limits

Every AI action (a mentor message or an AI tool run) costs one AI credit. Credits reset monthly.
| Plan | AI credits / month | Problem generation / month |
|---|---|---|
| Free | 90 | 20 |
| Go | 600 | 50 |
| Plus | Unlimited | Unlimited |
Track your usage in Settings → Billing & Usage. When you run out, you'll see a clear message and a one-tap upgrade option. Some tools (Pair Programmer, Contest Generator, Project Reviewer, Resume Analyzer, Mock Interview) require the Plus plan regardless of credits.
