CoCalc features

A persistent shared computer for technical work, with notebooks, terminals, documents, software environments, collaboration, and AI agents in one project.

• Online Jupyter Notebooks

  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.

• Online LaTeX Editor

  Write LaTeX online with real-time collaboration, side-by-side PDF preview with forward and inverse search, SageTeX, PythonTeX, and Knitr, discussions anchored to the source, and full edit history.

• Online Linux Terminal

  Use a full Linux terminal online in your browser: collaborative shell sessions that survive disconnects, preinstalled command-line software, and files, notebooks, and AI agents in the same project.

• Online Linux Environment

  Treat CoCalc projects as collaborative Linux environments with editors, terminals, files, and web-accessible services.

• Software Environments

  Every CoCalc project runs on a software image you choose: lean base systems or full scientific stacks with Python, R, Julia, SageMath, and LaTeX — customizable from inside the project.

• AI Agents

  Work with Codex near files, notebooks, terminals, screenshots, patches, review notes, and live notebook state.

• Whiteboard & Slides

  Use collaborative whiteboards and slide-sized pages for markdown, KaTeX math, Jupyter cells, diagrams, presentations, and project context.

• Teaching a Course

  Organize assignments, distribute files, collect work, and grade notebooks or other project files with a workflow built for technical courses, labs, and training environments.

• Python

  Use Python for technical computing, data science, and machine learning with a large preinstalled package set and collaborative tooling around it.

• R Statistical Software

  Work with R in notebooks, terminals, scripts, RMarkdown-style documents, Quarto-style workflows, Knitr, and shared course projects.

• Julia

  Run Julia in a collaborative project with Jupyter notebooks, Pluto, package environments, source files, terminals, and course workflows.

• SageMath

  Use SageMath for teaching, notebooks, SageTeX documents, source development, and long-running mathematics computations in a real collaborative Linux project.

• GNU Octave

  Use GNU Octave for MATLAB-style numerical computing in collaborative projects with notebooks, .m files, terminals, plots, and teaching workflows.

• HTTP API

  Use the CoCalc HTTP API for automation, integration, and provisioning workflows without depending on the web UI.

• Compare CoCalc

  CoCalc combines notebooks, terminals, documents, AI agents, course tools, sharing, recovery, and collaborative editing in one web-based technical workspace.
