Answers

What is included for free?

Day one of each study plan, automatic notes, your subject library and saved progress. You get 25 AI uses per day across tutoring, new topic guides, new notes, new plans and writing tools. Reopening saved topic guides or cached notes and plans does not spend an AI use. Topic guides do not count as uploads. Free uploads are limited to 3 a day and 10 a week, with up to 8,000 characters and 120 text lines per upload. Daily limits reset at midnight UTC; weekly uploads reset on Monday UTC.

What does Pro unlock?

Pro opens every day of your study plans and removes the Free daily AI allowance and upload-count limits. You can study larger chapters and decks, practice mistakes and adjust your exam schedule. Uploads support up to 300,000 characters and 6,000 text lines; file processing and abuse-prevention limits still apply. Pro is for individual study, not automated or shared-account use.

Where can I use my subscription?

One subscription unlocks Pro for the same account on the web and in the iPhone app. Study mode is on the web today; the iPhone app includes writing tools. Your study subjects sync between web browsers when you sign in.

How do billing and cancellation work?

Monthly plans renew each month; annual plans charge the full year upfront and renew each year. Cancel before your next renewal to stop future charges; access continues through the paid period. Manage web purchases in your account settings. Manage iPhone purchases through Apple Subscriptions. Your saved notes and progress stay in your account after Pro ends.
