CoCalc feature
Online Jupyter Notebooks
Collaborative notebooks with shared kernels and full edit history.
Run collaborative Jupyter notebooks with cell chat, TimeTravel history, course workflows, and AI agent tools. Select a local or remote kernel with the language and packages your analysis needs.
Use collaborative Jupyter notebooks when output, files, terminals, history, and review need to stay together.
Run Jupyter notebooks online
Use hosted Jupyter notebooks without installing the hosted runtime on your computer. Computations can continue after you close a tab while their kernel runtime remains running.
Choose an image, custom kernel, or registered remote kernel with the required language and packages. Native CoCalc Plus uses installed local tools; collaborators share the selected notebook kernel session.
- Real-time collaborative editing with visible cursors and shared kernel sessions
- Chat threads anchored to individual cells, plus TimeTravel edit history
- Course workflows for distributing, collecting, and grading notebook assignments
- CPU and memory gauges inform interrupt or restart decisions; save intermediate results before long runs
