A Complete Toolbox for Comprehension

OtterNote isn't just a summarizer. It's a suite of connected tools designed to help you tackle difficult reading from every angle.

Flagship Feature

Immersive Video Lectures

Turn any 20 pages into a 20-60 minute deep-dive class. Complete with narrated audio, a dynamic blackboard for visual notes, and synchronized page scrolling. It's like having a private tutor.

Between The Lines

Decode jargon instantly. AI insights appear in the margins of your document, clarifying complex paragraphs before you even have to ask.

Context-Aware Chat

Stop searching the whole book. Ask questions about the *exact* page you are reading. The AI knows your current context.

Smart Notes & LaTeX

Your thoughts stick to the page. Write sticky notes that stay where you put them, and snap photos of handwritten equations to convert them instantly into clean, searchable LaTeX.

Depth Over Summary.

Most AI tools try to shorten your reading by summarizing entire books into 5-minute clips. OtterNote does the opposite. We expand your understanding by providing deep, 20-60 minute lectures and line-by-line insights for specific chapters.

Multi-Modal
