Collaborative Calculation and Data Science

by Sagemath, Inc.

print('Welcome to CoCalc from Sage!', factor(2023))

Improve your research, teaching, and publishing using realtime collaborative Jupyter notebooks, LaTeX, Markdown, and Linux.

Mission: Enable better collaboration in science, engineering and mathematics by providing easily accessible and sustainable tools for computing, teaching, and publishing.

Collaborative editing

Have you ever been frustrated sending files back and forth between your collaborators? Do you spend too much time on reviewing changes and merging documents?
Share your computational documents like Jupyter Notebooks, LaTeX files, SageMath Worksheets, Computational Whiteboards and many more with your collaborators.
Everyone always stays on the same page, because all modifications are synchronized in real time and your code runs in the very same environment.

Available Tools

Sage Worksheets

Sage Worksheets are similar to Jupyter Notebooks, but made to work well with SageMath. They offer a single-document model that scales to large documents and integrated 3d graphics.

Linux Terminal

The very sophisticated collaborative Linux Terminal makes you incredibly productive. Many programming languages and hundreds of tools are available at your fingertips in a full Ubuntu Linux environment.

Made for Teaching

You can think of CoCalc as virtual computer lab in the cloud. It takes away the pain of teaching scientific software.
Hassle-free assignments: CoCalc keeps all files well organized! Due to real-time synchronization you never have to deal with multiple versions of the same file. There is even support for automated grading via NBGrader.
Pre-installed Software like in a computer lab, all software you need is already installed and ready to use.
Real-time Collaboration allows you to virtually look students over their shoulders. You can check their work directly and help them by editing the file or using side-chat communication.

And much more …

Available Software

CoCalc comes with a variety of software pre-installed, e.g. Python, SageMath and Octave. You can install additional software locally in your project as well.

Computational Whiteboard

Use a full featured collaborative whiteboard – with support for computational elements – to express and share your ideas.
