Story angles
- The app that can’t go online. Tabulay has no network permission at all. macOS enforces it, which makes “your data stays on your Mac” a fact rather than a promise.
- Past the spreadsheet’s last row. An Excel worksheet stops at 1,048,576 rows. Bank exports, order histories and research data don’t.
- The end of the silent change. Spreadsheets reformat values by default; in 2020 geneticists renamed 27 genes partly because of it. Tabulay never changes a value you didn’t ask to change.
- A free editor, monthly Pro. Eight advanced tools on subscription. Opening, editing and saving CSV files stay free when Pro expires.
- Tools for existing AI agents, planned. Tabulay CLI and an MCP server for CSV are a later stage, with no built-in model, no release date and undecided pricing and access.
- Made in Lille. An independent Mac app, designed and built in France to the standards of Apple’s own apps.
