Where UnivAI ends

3 things UnivAI can't reach

PDF-on-iOS is a great starting point. Here's what students still need to cover.

Gap 01

No live lecture capture

“Professor is talking — your iPad is showing a PDF reader.”

Truth: Class isn't a PDF. Most of the real content is spoken, not written.

ThetaWave records and transcribes the lecture live, then turns it into structured study notes.

Gap 02

No YouTube or audio

“Your professor's review videos sit on YouTube, untouched.”

Truth: PDF-only means half your study material can't get in.

ThetaWave handles PDFs, YouTube links, audio files and slides in the same workspace.

Gap 03

iOS-only, not cross-device

“You start on iPad, then need to write on your laptop — and the notes don't follow.”

Truth: Studying happens on phone, tablet and laptop. iOS-only leaves gaps.

ThetaWave runs on web and apps so your sources, notes and flashcards are everywhere you study.
