How can we help?

PDFs, PowerPoint slides and Word documents. Tap Upload in the app and pick files from your iPhone, iPad or iCloud Drive. Each upload shows its progress stage by stage, so you can follow along while Posie reads it.

Posie recognises a file it already has and points you to the existing copy, without processing it again. If a new document repeats material you have already added, only the new parts are processed, and your existing topics and progress are kept.

Every question is written from your own documents and checked against the source, and you can open the original page from any answer. AI can still make mistakes, so anything Posie is unsure about goes to your review queue, and you can flag a question at any time.

Every account comes with an AI allowance. It covers reading your documents into topics and questions, and grading written answers. Posie shows you the cost before it processes a document and only charges for what processing actually uses, so nothing is spent without you agreeing to it. If your allowance runs out, new uploads and written-answer grading pause until your plan renews or you buy more, and everything you have already built keeps working. You can buy more whenever you like from Tokens & plan in the app.

Build a test on a shared course and share it with a group or a connection. Each person who accepts gets their own copy with the same scope, question mix and difficulty. Questions are drawn for each person, so scores compare fairly without everyone seeing identical questions. Comparing results is opt-in: only people who share their score see other people's.

Only you. If you study a shared course, its creator sees class totals and averages, and only when at least five learners contribute. Your name appears only if you choose to share it for that course. See the Privacy Policy.

Leaving a course, or being removed from it, permanently deletes that person's progress on it. The app always asks before this happens.
