CastIQ-AI Notes, Quiz, Mindmap

One link, file, or class. Every study format.

CastIQ turns any YouTube video, uploaded file — PDF, photo, audio, or video — or a live-recorded class into clean, ready-to-use study material in minutes. Paste a link, pick a file, or hit record, 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

• Infographic — a shareable visual poster of your source's key ideas

• AI Slides — a presentation-ready slide deck, pick your slide count and theme

RECORD A CLASS

In a live lecture? Hit record right in the app — CastIQ keeps recording and captioning live even if you lock your screen or switch to another app, so you're not stuck holding your phone open for the whole class. See live captions as you go, then let CastIQ turn the recording into notes, a quiz, flashcards, or any format you pick as soon as class ends.

ASK IQ

Your built-in AI study partner — ask it about any topic, doubt, or the notes you just generated, and get grounded, on-point answers.
