Revise smarter, not longer.
CastIQ is the AI revision app built for the last week before the exam. Drop any source — a YouTube lecture, a PDF, a chapter from your textbook, a photo of your handwritten notes, an audio recording, or just the topic name — and get exam-ready in minutes.
WHAT YOU GET, EVERY TIME
• Revision Notes — clean, structured notes from any source • Quick Revise — a one-screen summary you can scan in 60 seconds • Practice Quiz — auto-generated MCQs to test what you remember • Revision Cards — spaced-repetition flashcards that stick • Mind Map — visual map of how the chapter's ideas connect • Revision Sheet — one-page cheat sheet for exam day • Slide Deck — presentation-ready deck for class or revision
PLUS THREE FEATURES YOU'LL ACTUALLY USE BEFORE THE EXAM
• Mock Tests — full timed exams generated from your own chapters, with negative marking and a real countdown • PYQ Solver — upload any past paper, get step-by-step solutions • Ask a Doubt — AI tutor that answers in your context, not the generic internet's. Math, science, anything
PER-FEATURE CREDITS — NO SUBSCRIPTION, NEVER EXPIRE
Each feature has its own counter. A mock test never burns your revisions, and a doubt never burns your solver runs. Credits never expire — buy once, use whenever the next exam shows up.
New accounts get a free trial: 3 revisions, 1 mock test, 1 PYQ solver run, and 10 doubts. Top up from ₹49 when you need more.
HOW IT WORKS
Drop a source — YouTube link, PDF, image, audio, video, file, or just a topic name.
Pick the format you want — notes, quick revise, quiz, flashcards, slides, mind map, or revision sheet.
CastIQ generates a revision-ready output in minutes. Save it to a subject, share with a friend, or export as PDF.
