You've probably tried ChatGPT

A great writer.
A terrible IB colleague.

Generic AI can draft an essay, but it can't tell Criterion B from Criterion D, and it forgets everything the moment you close the tab. You end up re-teaching it the framework on every prompt. We did that work once, so you don't have to.

“Every rubric comes back with the right strand split for my subject — A has three, B has three, C has four. I'm not editing the structure any more, just the wording.”

Questions

Common questions.

Yes. The teacher toolkit, Unit Planner, Lesson Planner, Assessment Generator, Rubric Maker, Feedback Writer, Slide Decks and more, is free for individual teachers. Paid school plans with roster management and analytics come later; the core tools stay free for individuals.
No. Sign-up is open to any IB teacher, MYP or DP, with a valid email. No domain restrictions, no waitlist, no approvals, you can be generating your first rubric in about a minute.
Both programmes. The MYP toolkit covers all nine subject groups across MYP 1–5 (criteria A–D, command terms, achievement levels 1–8), and DP support spans the subject groups with assessment objectives, paper-style questions, and IA-aware feedback. Content libraries span Sciences, Mathematics, Individuals & Societies, Language & Literature, Language Acquisition, Design, and the Arts.
Student work is stored encrypted and never used for training. Google Calendar sync is read-only, we never modify, delete, or create events; we only read the classes you map during setup. You can export or delete anything on request.
PrepAiro is IB-native. Every output is tagged with the right criterion, command term, and achievement level, the tools share context (your SOI feeds your unit, your unit pre-fills your lessons), and your roster keeps feedback history across the year. It's a colleague who already knows the framework, not a blank box you re-brief every time.
Planning, assessment, feedback, slide decks, video lessons, content library, paper-mode quizzes and calendar sync are all live. Class Analytics is in preview, a deeper AI pass on class-wide trends and individual progress arrives once the results pipeline lands. We'd rather show you what's real than oversell a roadmap.
