The power of an analyst, the privacy of a local file
Most AI spreadsheet tools quietly upload your file to their servers. Gribly is built the opposite way — fast, capable, and completely private.
Privacy by architecture
Every calculation runs locally in your browser. Your spreadsheet is never uploaded, stored, or seen by anyone — not even us.
Plain-English questions
No SQL, no pivot tables, no formulas. Just ask what you want to know and get a clear answer back.
Answers in seconds
First answer in 5–10 seconds. Follow-up questions land in under two.
Up to 1M rows
Built to chew through large, messy, real-world datasets without breaking a sweat.
Charts that explain
Get auto-generated visualizations alongside natural-language explanations of what the data means.
Zero data sent to servers
There's no backend round-trip for your data. Disconnect your wifi mid-analysis and it keeps working.
From spreadsheet to insight in three steps
No setup, no onboarding, no learning curve. If you can open a file, you can use Gribly.
Drop in your file
Drag an Excel or CSV file into Gribly. It loads straight into your browser — nothing is uploaded anywhere.
Ask in plain English
Type your question like you'd ask a colleague. "What were my top 5 customers last quarter?" Done.
Get answers & charts
Gribly computes locally and replies with a clear explanation plus the right visualization in seconds.
Analysts, founders, and finance teams trust Gribly
“I deal with client financials all day. Gribly is the first AI tool I actually trust — nothing I open ever leaves my laptop.”
“It answered a question about 600k rows of sales data faster than I could've built the pivot table. Follow-ups are basically instant.”
“No formulas, no uploads, no nonsense. I asked 'what's driving the dip in March?' and got a clear, plain-English explanation right away.”
Simple pricing. Absurd value.

Questions, answered
Correct. Gribly loads and analyzes your file entirely client-side using your browser's own compute. There is no upload step and no server copy of your spreadsheet — ever.
Excel (.xlsx, .xls) and CSV files are supported. You can drop in multiple files and switch between them freely.
Gribly handles datasets of up to 1 million rows. Performance depends on your device, but most questions return an answer within 5–10 seconds.
Not at all. You ask questions in plain English and Gribly figures out the calculations for you, then explains the result in clear language.
Free gives you 15 questions a month with all core features. Plus ($1/month) bumps you to 100 questions, prioritizes response speed, keeps your projects from auto-deleting, and includes priority support.
Your raw spreadsheet data stays on your device. Only your question and the small computed result needed to phrase a natural-language answer are processed — never the underlying rows.
Your spreadsheets have answers. Go get them.
