CoCalc feature
Online Jupyter Notebooks
Collaborative notebooks with shared kernels and full edit history.
Run Jupyter notebooks online in a shared CoCalc project: real-time collaboration, chat anchored to cells, TimeTravel history, managed kernels, course workflows, and AI agent context nearby.
Use collaborative Jupyter notebooks when output, files, terminals, history, and review need to stay together.
Why it matters
CoCalc notebooks stay compatible with the Jupyter ecosystem while adding the collaboration, teaching, and operational features that are awkward to bolt on later.
Kernel state, output, and widgets can be shared across collaborators, which makes notebooks practical for classes, pair work, and support sessions.
Highlights
- Real-time collaborative editing with visible cursors and shared kernel sessions
- Built-in TimeTravel and recovery tools for recovering earlier notebook states
- Course workflows for distributing, collecting, and grading notebook assignments
- Managed kernels with many languages and preinstalled scientific software
