1. SUM in B11 skips B10 (range gap)
2. Row 7 amount is 8× the column average (outlier)
No other spreadsheet catches these errors
The smartsh!t Auditor detects range gaps in SUM formulas, inconsistent column patterns, statistical outliers, circular references, and hardcoded magic numbers — automatically, in your browser, with zero latency.

Built for people who hate spreadsheets
Describe what you want and let the AI handle the rest.
The Auditor catches formula errors
A local formula check looks for skipped cells in SUMs, inconsistent formula patterns, statistical outliers, and hardcoded constants. It runs in your browser, with no account. Auto-fix is limited on the free plan.
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.
The workbook stays in your browser
The file is not uploaded unless you turn on cloud backup. The auditor stays local. An AI question sends that question and a cell summary to our server, or to your own provider if you bring a key.
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.
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.
Fast hybrid AI architecture
Common requests like budgets, invoices, sorting, and formatting resolve locally in milliseconds — no API round-trip needed. Complex questions use cloud AI with streaming responses so you're never waiting on a blank screen.
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.
Bring Your Own API Key
Use your own OpenRouter, Groq, or OpenAI key. We do not bill those calls. The prompt and cell summary go to the provider you chose, and that provider bills the tokens.
