Your CS lecture just became an IDE.
Video + editor + AI — one canvas, zero tab-switching.
What makes Niotebook different
The best free courses.
A better way to learn from them.
The world’s best CS courses. Free. Open. All in one place.
Niotebook is the digital library of the best free MOOCs — massive open online courseware from institutions like Harvard, MIT, and creators who believe education should be accessible to everyone. Every course, every lecture, completely free and open source. We just made the experience of learning from them radically better.
A smart code editor that follows along.
No more tab-switching between the lecture and your IDE. Niotebook’s integrated code editor lives right next to the video — syntax highlighting, multi-language support, and instant execution. Pause the lecture, edit the code, run it, see the result. All without leaving the canvas.
A friendly, Socratic AI that actually gets it.
Not a chatbot that guesses. Nio knows what lecture you’re watching, what code you’ve written, and exactly where you’re stuck. It asks questions before giving answers, nudging you toward understanding rather than handing you solutions. Like a brilliant TA who never sleeps.
All courses are freely available thanks to institutions and creators like Harvard, MIT, Yale, and others who believe great education should be open to everyone. We're just building the best environment to learn from them.
How it works
One canvas.
Everything you need.
Video + Code in Sync
The lecture plays. The editor follows. Pause the video — the code is already there, cursor blinking, ready for you to run.
AI That Reads the Room
Your tutor knows what slide you’re on, what code you wrote, and where you got lost. Context-aware help, not generic answers.
Python, JS, C, and More
Switch languages mid-lesson. The runtime follows. From Python scripts to C pointers — one workspace, every language.
Learn by Shipping
Every concept becomes runnable code in seconds. No setup, no boilerplate. Type, run, understand — then do it again.
