Astra

Astra turns your own notes, slides and past papers into a dated study plan with guided lessons, flashcards, podcasts, quizzes and graded mock exams, aimed at students preparing for school, university or official exams.

Astra is an AI tutor built around exam preparation rather than general chat. The starting point is your own material: lecture notes, PDFs, photos of handwritten pages, slides, textbooks, past papers, video lectures and web links. You add the exam date and a target grade, and the tool builds a topic by topic study plan around what will actually be tested. A mastery indicator tracks how far you have come, and every session is meant to move that number forward. The learning formats are the part that distinguishes Astra from a plain question and answer bot. A single topic can be worked through as a guided lesson, a smart text lesson, flashcards, a quiz, true or false drills, short exercises, a spaced repetition cycle, a knowledge gap review, or an auto generated podcast. When a problem is stuck on paper, a photo of it can be scanned and walked through step by step. The tutor also runs graded oral mock exams, where answers are spoken aloud, and full timed written mocks, so the format of the real assessment is rehearsed rather than just the content. Exam programmes for official qualifications are available as ready made starting points, and the wider product adds interactive 3D simulations and visual models across subjects, plus brain games and streaks for habit building. Thousands of students use it, the iOS app carries a 4.73 rating, and there is a stated two grade improvement guarantee with a refund if the grade does not move up by at least two levels. Teachers and parents get dedicated pages for their side of the workflow. Astra sits closest to AI study assistants and flashcard apps, but leans harder on planning and assessment than on conversation alone. It is aimed at school, university and professional exam candidates who have material to work from and a date to work toward. The math lesson support fits the same pattern: upload the coursework, then drill the procedures through worked examples, quizzes and a mock exam rather than reading proofs passively.
