Your personal AI tutor for every subject, from notes to exam day.
Upload your notes, slides or past papers, set your exam date and target grade, and Astra assembles a topic-by-topic revision plan built around exactly what you'll be tested on.
Ask by typing, speaking or snapping a photo. The tutor explains concepts at your level, asks follow-up questions and keeps going until the idea actually clicks.
Generate guided lessons, flashcards, quizzes, true/false and smart-text exercises, plus an auto-generated podcast so every learning style is covered.
Practise with realistic oral and timed written mock exams that get graded, so you know where you stand before the real thing.
Turn your own notes and PDFs into lessons, flashcards and exam practice
Import PDFs, Word docs, PowerPoint, Excel, pasted text, YouTube videos, web links and Google Drive files into a single study space, with OCR for scanned PDFs.
Four study modes built from the same material: guided lessons, spaced-repetition flashcards, out-loud teach-back sessions and adaptive practice tests.
Written answers get graded by AI and quiz difficulty adjusts to how you are actually performing, so weak topics get repeated more often.
Pro builds question banks and timed mock exams for targets like NCLEX-RN, MCAT, USMLE Step 1, the CPA Exam and CompTIA Security+, then points you at the areas to revisit.
