DeepCell is an AI-powered productivity tool that turns your work and ideas into interconnected documents, spreadsheets, and presentation slides stored in a single .deepcell file. When you update one number or piece of data, the change flows automatically through all linked content. The tool also generates cheat sheets that trace figures back to their sources, making it easy to explain your reasoning. DeepCell integrates with AI agents via a plugin and CLI, allowing users to build complete project kits from a task description or existing file.
