Words of appreciation from our community
Join thousands of students and researchers who trust OpenBook for their learning journey.
OpenBook has completely transformed how I study for my medical exams. The AI explanations are spot-on and save me hours of searching.
The graph view is unlike anything I've used before. Connecting ideas has never been this intuitive. Ideally, every student needs this tool.
Finally, a notebook that actually helps me think. It's not just storage; it's an active partner in my research process.
The aesthetic is just... chef's kiss. Clean, minimal, and functional. It makes me want to write more just to see it on the page.
I recommend OpenBook to all my students. The ability to chat with your notes changes the game for comprehension and retention.

As a designer, I appreciate the attention to detail. The dark mode is perfect for late-night brainstorming sessions.
The way it handles context from multiple documents is impressive. It feels like having a second brain that actually works.
Writing my thesis with OpenBook has been a breeze. The distraction-free interface keeps me focused on what matters.
Simple, fast, and effective. The onboarding was smooth, and I was productive within minutes. Highly recommended.
I used to drown in PDFs. Now I swim through them. The semantic search is a lifesaver for finding specific details.
