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.
LLMs are here to help you
CoCalc's file editors are enhanced by large language models like ChatGPT. They help you fixing errors, generate code or LaTeX snippets, summarize documents, and much more.
Many Programming Languages
CoCalc supports many programming languages. Edit the demo cell on the left and evaluate it by pressing "Run". You can also select a different "kernel", i.e. the programming language that is used to evaluate the cell.
Collaborative Computational Documents
CoCalc makes it possible to collaboratively edit computational documents with your colleagues, students, or friends. Edit Jupyter Notebooks, LaTeX files, SageMath Worksheets, Computational Whiteboards and many more with your collaborators in a real-time.
The code code runs in the same environment for everyone, giving consistent results. All changes are synchronized in real-time.
Therefore, you can forget the frustration of sending files back and forth between your collaborators. You no longer waste time reviewing changes and merging documents.
Available Tools
Jupyter Notebooks
CoCalc's own Jupyter Notebook implementation offers realtime synchronization, TimeTravel, automatic grading, side chat, and more.
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.
Teach a Course
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 directly in your project as well.
Computational Whiteboard
Use a full featured collaborative whiteboard – with support for computational elements – to express and share your ideas.
