Recalc is an experimental, open-source desktop spreadsheet designed as a shared workspace for people and AI coding agents. Cells can contain ordinary values, formulas, terminal commands, actions, or prompts for agents such as Claude Code and Codex. Formulas update when their inputs change; commands can rerun as inputs change; agent prompts run when requested. Agents can write plans and results into the grid, while users guide them by editing cells, reviewing outputs, or opening a cell’s agent session in a terminal. An MCP server lets agents working in their usual chat interact with the board.

The project’s central idea is to make agent work observable and checkable rather than bury it in separate chat sessions. Users can pair an agent’s completion claim with tests, arrange documents and questions in a grid to produce cited answers, coordinate several agents, or use formulas to validate financial data. A “Needs You” list gathers questions, errors, and completed work requiring attention. Boards save locally as folders, and results can be exported to Excel; agents can also use local models for sensitive documents. Recalc is free, but agents use the user’s existing provider accounts. It is in early beta, runs on macOS with experimental Linux support, and does not yet support Windows. Commands run with the user’s permissions, so the app is not a security sandbox; actions that change things require explicit user initiation.
