New · WebMCP
Built for AI agents
Edit your documents, spreadsheets and slides straight from ChatGPT and any WebMCP browser agent. WebDecks, WebDocs and WebSheets expose their documents through WebMCP (the Web Model Context Protocol), so an agent can read, edit and export your real files — in the app or via a standalone endpoint. Nothing is uploaded; your files stay on your device.
- Read the real document model — text, tables, cells, shapes and formulas
- Make real edits and export to PPTX, DOCX, XLSX or PDF
- In-app on webdecks.app, plus a standalone /mcp/ endpoint
