# Formula Foundry

> The formula editor Google Sheets and Microsoft Excel forgot to build. Multi-line editing, global `@@variables`, an Excel→Sheets translator, an AI assistant, and a team snippet library — all inside the spreadsheet sidebar.

Formula Foundry is a Google Workspace add-on (Sheets) and a Microsoft 365 add-in (Excel). It runs entirely inside the visitor's spreadsheet — no data ever leaves the user's session. Pricing is freemium: a permanent Free plan (no credit card), Pro at $15/seat/month billed annually ($19 monthly), and Business at $24/seat/month billed annually ($29 monthly). Anyone can start free, no card required.
