Show HN: CheatSheet An Open-source spreadsheet you can talk to

I built CheatSheet, an open-source Google Sheets alternative that lets you cheat at spreadsheets.

Say "update the expenses column" or "add a new row with this data" and it manipulates cells through AI. Has multiple tabs and connects to external data through MCP servers (Linear, GitHub, Supabase).

Adding formulas, graphs, voice input, thinking, and more features next!

Built with React and Tambo AI. Runs in your browser with your own API keys.
