Credits and pricing
One credit equals one AI action. Credits are bought in one-time packs — there is no subscription — and they never expire.
How a credit is spent
Every paid action in ClaudeLab debits credits at the moment it runs. The debit is logged in your account and visible from Profile → Billing → Usage. If a request fails after the debit, the credits are refunded automatically and the refund row appears in the same usage list.
Cost per action
The list below is canonical. The same numbers are shown on the public pricing page on claudelab.me/pricing, which is the source of truth — if any number on this docs page drifts, that page wins.
| Action | Cost | Notes |
|---|---|---|
| Evaluation question | 1 credit | Adaptive diagnostic, per question |
| Practice session message | 1 credit | One ARIA turn in a chat session |
| MCQ batch (10 questions) | 5 credits | A generated study quiz |
| Daily plan generation | 2 credits | Per re-plan; auto-runs daily |
| Voice mode turn | 3 credits | Speech-to-text + ARIA + text-to-speech |
| Voice session report | 5 credits | Closing summary at end of voice session |
| Weakness report | 5 credits | Deep-dive on a weak domain |
| Exam-day warm-up | 2 credits | Warm-up plan the day before |
| Post-exam debrief | 2 credits | Reflection plus AI feedback |
Other internal events you may see in your usage history — milestone restructure, recovery message, career path mapping, material indexing — follow the same model and surface in the list with their own credit cost when they run.
Voice mode is the heavy spender
Voice mode is the only action that runs on the order of three credits per turn rather than one. A short voice session is therefore considerably more expensive than a chat session of the same length. ClaudeLab pre-gates voice mode at a 30-credit floor — about ten turns of headroom — so a voice session does not start unless I am confident you can finish it without running dry mid-conversation.
If you plan to lean on voice mode, the 2,500-credit pack and the 6,000-credit pack are sized for it.
Low-balance signals
I show two warnings before you actually hit zero:
- Below 20 credits — a yellow warning on the billing screen and a hint to top up soon.
- Below 10 credits — a red warning on the billing screen and a stronger nudge to top up before your next session.
The credits balance pill is also pinned to the top right of every screen in the app, so the number is always one glance away.
The "out of credits" modal
If you start an action and your balance is below the cost of that action, I do not silently fail. A paywall modal opens, names the action, shows the required cost vs. your current balance, and offers a Top up button that opens the pack picker right there. Your roadmap and progress are unaffected — you can pay, return to the app, and the next action will run with the topped-up balance.
Credits never expire
Once granted to your account, credits stay there. Whether they came from the onboarding starter grant, a pack purchase, or an admin grant, they have no expiry date. They are spent in FIFO order — oldest grants first — but that ordering is invisible to you and only matters for the refund calculation in Refund policy.
