GoKawiilRecalc turns spreadsheet cells into terminals for Claude Code and Codex agents
Recalc is a new open-source spreadsheet application that lets any cell function as an AI agent terminal, running Claude Code, Codex or an experimental 'pi' agent. Users can watch agents fill cells live, open any cell as its own terminal, and redirect an agent by editing the cell it's writing to rather than typing a new chat prompt. The tool is in early beta, available for macOS and experimental Linux, and runs locally on the user's machine.
GoKawiil's interpretation of the reporting above, not reported fact.
By embedding agents directly into spreadsheet cells, Recalc proposes a different interaction model than chat-based AI coding tools, letting other cells (like test runners) automatically verify an agent's work in real time. This could make it easier to catch cases where an agent claims a task is finished while checks are still failing, though as early beta software it may still have significant bugs and breaking changes.
- Recalc is a free, open-source spreadsheet where cells can act as AI agent terminals.
- It supports Claude Code, Codex, and an experimental agent called pi, via an MCP server.
- The project is in early beta for macOS and experimental Linux, with warnings about instability.
