Immersive Video Lectures That Actually Teach

Unlike 20-minute summaries of entire books, you get 20-60 minutes of real teaching for every 20 pages. It's like having a professor personally guide you through the material.

Narrated Audio

Professional lecture narration that explains concepts clearly

Dynamic Blackboard

Visual notes appear in real-time alongside your reading

Auto-Scrolling Pages

Your PDF follows along automatically as the lecture progresses

Smart Highlighting

Key passages light up exactly when they're being discussed

Depth Over Gimmicks

We limit lectures to 20 pages maximum, ensuring you get 20-60 minutes of genuine, in-depth teaching—not a rushed summary. Every concept gets the time it deserves.

Reading Tools That Actually Help You Understand

Beyond lectures, OtterNote provides reading tools that actually help you understand—like having a smart friend who's always on the same page.

Between The Lines

See what matters on every page before you even read it

Like having expert annotations in the margins for every page and document. AI insights appear right next to the passages they explain. Hover over any annotation to see the exact text it's referencing.

AI That Knows Where You Are

Ask questions about what you're reading right now, not the whole document

Unlike ChatGPT or NotebookLM that search your entire PDF, OtterNote knows exactly what page you're on. Highlight any confusing text and get help that's actually about what you're reading.

Turn Messy Notes Into Clean Text

Snap a photo of your handwritten equations and get perfect LaTeX

No more retyping math homework or lecture notes. Take a picture of your handwritten work and instantly get clean, searchable text, even for complex formulas.

Notes That Stay Where You Put Them

Your thoughts stick to the exact page where you had them

Write notes that automatically attach to the page you're reading. When you come back weeks later, your insights are right there waiting, no searching required.
