CoCalc

Collaborative Calculations

What is CoCalc?

CoCalc’s goal is to provide the best real-time collaborative environment for Jupyter Notebooks, LaTeX documents, and SageMath, scalable from individual use to large groups and online courses. We empower you to focus on the task at hand rather than technical details.

CoCalc: Collaborative Calculations and Data Science

Realtime Collaboration

Realtime collaboration
Whether you're working on academic research, data analysis, or educational content, CoCalc revolutionizes collaborative work on computational documents, eliminating the need for cumbersome file exchanges and time-consuming change reviews.
It supports a wide range of document types, including Jupyter Notebooks, LaTeX files, SageMath Worksheets, and Computational Whiteboards.
As you work together, file changes are synchronized in real-time, and an automatic revision history is maintained. This feature allows you to easily track changes and revert to previous versions when needed, enhancing transparency and accountability in collaborative projects.

Chat Rooms

Chatroom
CoCalc's chatrooms offer a range of features to enhance communication and collaboration:
  • @-mentions for directly addressing collaborators or querying a language model
  • Emoticons support for expressing emotions
  • LaTeX formula rendering between $ signs
  • Threads and Hashtags for easy topic organization
  • Image insertion via upload or drag-and-drop
  • Markdown syntax for text formatting and link insertion
  • Notifications system with a bell icon for alerting users to new activity

Many Programming Languages

Compute Servers with GPU support

Extend your CoCalc projects with powerful compute servers. They give you much more power, GPU options, and flexibility for your computations. From within your project, spin up and connect to a powerful machine and tell your terminals and Jupyter Notebooks to run on these machines.
These servers optionally come with very competitively priced GPU support, they are billed by the second and your files are seamlessly synchronized between your project and servers.
