Predictive Spreadsheet
Add a column — Sentiment, Urgency, Churn risk — and Jev fills it for every row, live. No key, just click a column.
↑ Click a column — Jev computes it for every row of the sheet, live.
A live demo of Jev over tabular data. Upload your own CSV and ask up to 8 questions in the Batch Analyzer.
The same demo is one Jev call
- Pick a new column — sentiment, urgency, intent…
- For each row, ask Jev that one question
- Fill every row in parallel
- Append the typed value as a column

How it works
Add a column and Jev fills it for every row at once — each cell is one real API decision, streamed in as it returns, in a second or two for a fraction of a cent. Add another column and it does the same again. It is the spreadsheet-native way to run typed decisions (classify, score, flag) over a whole table.
Bring your own data
This demo uses a small sample. To upload your own CSV and ask up to eight of your own questions per row — then filter, sort and export — use the Batch Analyzer with a hosted key. Same Jev call, your data.
FAQ
Is each cell really computed by AI?
Yes — every cell is an independent Jev API decision. When you add a column, the whole column is computed in parallel and streamed in live.
Can I use my own spreadsheet?
Yes — upload a CSV and ask your own questions in the Batch Analyzer with a hosted key. This page is a fixed sample to show the experience.
How fast and cheap is it?
Free and no key here. A column over a dozen rows fills in about a second and costs well under a cent; the page shows the running total.
