Questions about billing and credits
AI credits power intelligent features like auto-generating notes, creating diagrams, making flashcards, and transcribing YouTube videos. Each action is priced from its actual token usage, so the cost depends on the AI model you choose — the credit numbers shown around the site are typical examples, not fixed rates. All other features, like storing notes, organizing folders, and manual editing, are unlimited.
Your credits refresh at the start of every billing cycle. If you run out before then, you can upgrade to a plan with a larger monthly allowance, or wait for the next refresh. Nothing is ever charged automatically — you choose if and when to add more.
No. Your credit allowance refreshes at the start of each billing cycle, monthly on monthly and annual plans and every week on weekly ones (1/4 of the monthly allowance each week), and unused credits do not carry over.
The Free plan is the easiest way to start, with 500 AI credits a month. To try a paid plan, pay for it by the week (Starter $1.99, Plus $3.99 a week) and cancel anytime. The Free plan never needs a card.
Absolutely. Cancel your subscription anytime from your account settings. You'll retain access to paid features and your remaining credits until the end of your current billing period.
Weekly plans bill every 7 days. Monthly plans bill on your signup date each month. Annual plans bill once per year at a discounted rate. Your subscription only ever charges your plan price — there are no usage-based or overage charges. Top-up packs are a separate, optional one-time purchase, never billed automatically. We accept all major credit cards.
Yes, upgrade anytime to get more credits. When upgrading, you're charged a prorated amount for the remainder of your billing period. Downgrades take effect at the end of your current billing cycle to avoid losing paid time.
Free includes 500 AI credits/month (≈ 8 questions or ≈ 15 summaries), enough to try note generation, diagrams, and flashcards. Starter includes 30,000 credits/month for regular learners, and Plus includes 120,000 credits/month for power users, with unlimited diagrams and flashcards. Paid plans also unlock integrations, extra linked accounts, and priority support. See the plan comparison above for details.
Refunds are handled as set out in our Terms of Service: contact us at [email protected] and we'll review your request. You can cancel anytime to stop future charges.
Plus gives you 120,000 credits a month, 4× Starter and 240× Free. If you're a power user who consistently needs more, top up with a credit pack, or reach out to our team and we'll help you find the right setup.
No hidden fees. Your subscription only ever charges your plan price — there are no usage-based or overage charges. If you run out of credits, you can wait for your monthly reset or upgrade; nothing is ever added to your bill without you choosing it. Everything is transparent.
