About Astra AI

Exam Prep Study Plans

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.

Step-by-Step AI Tutor

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.

Multi-Format Learning

Generate guided lessons, flashcards, quizzes, true/false and smart-text exercises, plus an auto-generated podcast so every learning style is covered.

Graded Mock Exams

Practise with realistic oral and timed written mock exams that get graded, so you know where you stand before the real thing.

Mastery Tracking & Streaks

See mastery percentages, learning time and knowledge gaps, and stay motivated with daily streaks, milestone badges and brain games.

Astra AI positions itself as a full study companion rather than a simple question-answering chatbot. Instead of dumping answers, it tutors step by step: it asks questions back, checks understanding and refuses to move on until the concept genuinely lands. The platform is designed around the material a student is actually being tested on, so every lesson, quiz and mock exam is grounded in their own coursework rather than generic internet content.

The experience combines multiple learning formats. Students can chat with the tutor, snap a photo of a problem for a walkthrough, generate flashcards, or listen to an auto-generated topic podcast. Exam Prep sets a target date and grade and then assembles a topic-by-topic schedule, while mock oral and written exams simulate the real thing and are graded so nothing catches the student off guard. Progress features like streaks, badges, mastery tracking, interactive 3D simulations and brain games round out the habit-building side.

Astra AI reports more than 19 million students and 342,000+ five-star ratings, with an average App Store rating around 4.7 stars. It offers a genuinely free starting point with no card required, and paid tiers (Plus and Sigma) unlock higher usage limits and premium features for a fraction of the cost of private tutoring.
