Turn your notes into a complete study system.
Upload lecture notes, slides or a textbook chapter. Sayak builds illustrated SmartCards, adaptive quizzes and one-page infographics from them — and Ava, your AI tutor, explains whatever you get stuck on.
No credit card required · 30 free credits
Cards written from your material, with a visual on every one.
Sayak reads the page and writes the cards a good student would — one idea each, phrased as a question, with the supporting detail a tap away.
- Question, answer, and the detail behind itExpand any card to see the full explanation drawn from your own notes.
- AI-generated diagramsEach card gets an illustration that matches the concept, not clip art.
- Star what you missMark cards to come back to; adaptive quizzes target what you have not mastered yet.
Ask about your notes, not the internet.
Ava is the tutor built into Sayak. She has already read your material, so her answers stay on your syllabus instead of drifting to generic explanations.
- Knows the card you are onAva has read your upload and answers in the context of what you are studying.
- Explains at your levelPlain-language first, exam depth when you ask for it.
- Text or voiceType a follow-up or talk it through. Available on every paid plan.
One page that shows how it all connects.
Every study set can become a single poster you can take in at a glance — the structure of a chapter on one page, ready for the night before the exam.
- The right layout for the subjectA timeline for history, a side-by-side for comparisons, a hub for one central idea.
- Styled to the materialColors and illustration match what you are studying — greens for biology, navy and gold for finance.
- Yours to keepDownload as PNG, print it, or share it with your study group.
Quizzes that find what you have not learned yet.
Questions are generated from the same material as your cards, so a quiz is never about something you did not study.
- Adaptive by defaultQuestions weight toward the cards you starred or answered wrong.
- Feedback that teachesEvery miss comes with an explanation, a memory aid and a study tip.
- Two credits a quizCreating a quiz costs two credits; reviewing your results is free.
See exactly what to study next.
Sayak tracks every card you flip and every question you answer, and turns that into a short, honest answer to the only question that matters the night before: what now?
- Progress over timeAverage quiz score, study time and mastery, week by week.
- Time spent by topicMinutes per study set, so you can rebalance before the exam.
- Quiz performanceEvery attempt scored and kept, with the trend over time.
