A full spreadsheet, not just a chatbot
Everything you'd expect from a desktop spreadsheet — plus AI that actually understands your data.
Built for people who hate spreadsheets
Describe what you want and let the AI handle the rest.
Plain English, real results
Say "track my expenses" or "build an invoice" and it happens. The AI spreadsheet assistant handles formulas, formatting, and calculations — a true Excel alternative for people who want results without the learning curve.
Your data stays on your machine
Unlike cloud-only tools, your spreadsheet data lives in your browser by default. A privacy-first spreadsheet where nothing syncs to our servers unless you explicitly enable cloud backup. Self-hosted friendly.
The Auditor catches formula errors
An AI-powered spreadsheet auditor checks for skipped cells in SUMs, inconsistent formula patterns, statistical outliers, and hardcoded constants. Finds mistakes before they compound — something Google Sheets and Excel don't do automatically.
Preview before anything changes
Every AI suggestion shows an interactive diff preview first. Approve or reject with one click. Your data is never modified without explicit consent — building trust that no other AI spreadsheet tool offers.
Excel import and export
Bring your existing .xlsx and CSV files. Export back anytime. Works alongside your current workflow as a modern spreadsheet replacement — no vendor lock-in, no migration friction.
Instant local AI — no waiting
Common requests like budgets, invoices, sorting, and formatting resolve locally in milliseconds through our hybrid AI architecture. No API round-trip, no loading spinner. 80% of operations are instant and free.
50+ ready-made templates
Monthly budgets, expense trackers, invoice generators, sales dashboards, project trackers, GPA calculators, workout logs, and more. Professional-grade spreadsheet templates built by AI in seconds.
