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 long videos and audio into short text summaries
Works with links from YouTube, Vimeo, Facebook, Google Drive, Dropbox, Twitter, Telegram and other supported sites, so you don't need to download the file first.
Upload video or audio files stored on your laptop or phone and get the same summary output without hosting them anywhere publicly.
Built to summarize files up to roughly three hours, covering full lectures, webinars and lengthy meeting recordings.
The goal is to strip unnecessary detail and surface the key points, so the summary reads faster than a raw transcript.
