Learning is shifting toward AI-first study support
The shift is clear: learners expect personal guidance, faster feedback, and study tools that adapt to their pace.
We're at the cusp of using AI for probably the biggest positive transformation that education has ever seen.

Questions before upgrading?
Clear answers about billing, credits, top-ups, and what changes when you move between plans.
Pro and Max include the same product features. Max gives you a larger monthly AI credit allowance for heavier document, podcast, and daily study workflows.
Credits are based on the model used. GPT-5 Mini uses 1 credit per token, GPT-5.1 uses 12 credits per token, and podcast generation uses weighted TTS usage.
No. Yearly plans are billed once per year, but AI credits still reset monthly so usage stays predictable throughout the year.
Yes. Paid users can add one-time credit top-ups when they need more room before the next monthly reset.
Yes. You can manage or cancel your subscription through Stripe, and access continues until the end of the current billing period.
Your saved trees and content remain in your account. Your future AI usage follows the lower plan allowance after the billing change takes effect.
