CastIQ: AI Notes, Quiz & PPT

CastIQ

About this app

One link or file. Every study format.

CastIQ turns any YouTube video or uploaded file — PDF, photo, audio, or video — into clean, ready-to-use study material in minutes. Paste a link or pick a file, choose a format, and let AI do the rest.

WHAT YOU GET

• Notes — clean, structured notes from any source, with math rendered natively
• Quiz — auto-generated MCQs with explanations to test what you remember
• Flashcards — question → answer cards for quick flip-and-recall
• Mind Map — a visual map of how the topic's ideas connect
• AI Presentations — a presentation-ready slide deck, pick your slide count and theme

QUESTION SOLVER

Stuck on a question paper? Upload it and CastIQ solves every question step-by-step, with clear explanations — not just the final answer.

YOUTUBE PLAYLISTS

Import an entire YouTube playlist in one go and generate study material for every video in it, not just one at a time.

TRY IT FREE, THEN SUBSCRIBE

Every new account gets one free try of each tool — one Notes/Quiz/Flashcards/Mind Map generation, one question solve, and one AI presentation. No time limit, no card required.

After that, subscribe to unlock unlimited use of every feature:
• 1 month — from ₹99
• 6 months — from ₹499
• 1 year — from ₹999

All plans include every feature. Only the duration and price differ, and plans never auto-renew — you're only ever charged when you choose to buy.

HOW IT WORKS

1. Paste a YouTube link or upload a PDF, photo, audio, or video file.
2. Pick a format — notes, quiz, flashcards, mind map, or presentation.
3. Get your result in minutes. Save it, share it, or export it as a PDF.

PRIVATE & SECURE

• Razorpay-secured checkout for purchases
• Your generated content is yours — accessible anytime from your library
• No subscription that auto-charges your card every month

A FEW THINGS WE'RE PROUD OF

• Math renders natively — no blurry screenshots of formulas
• Works from a YouTube link, a photo of a textbook page, an audio recording, or a video file — not just PDFs
• The question solver explains its reasoning, not just the answer
• Built to stay fast and light, even on modest phones
