Message
Hi, I was charged twice this month and I'm really frustrated. Please fix this today.
Just wanted to say your product is amazing, it saved my team hours this week!
The export button hasn't worked for 3 days. This is blocking our reporting.
Can you tell me how to change my billing email? Not urgent.
I'm cancelling. Too expensive and I barely use it anymore.
Login is down for our whole company since this morning — need help ASAP.
Loving the new dashboard update, great work.
Reminder: our contract renews next month, can we discuss a discount?
Why did my subscription renew without warning? I want a refund.
Quick question — does the API support webhooks?
Everything is fine, just checking in. Thanks!
We've had three outages this week. Seriously considering switching.

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.
