Run Jev on a whole file
Upload up to 1,000 rows, choose the questions, and get a typed answer with a probability for every row — then export the results as CSV. Each row costs the same credits as one evaluation, and rows that fail are refunded.
How it works
- 1
Upload
CSV with a header row, plain text (one item per line) or JSONL, up to 2 MB and 1,000 rows. The file is read in your browser.
- 2
Choose questions
Load a saved question set, start from an example, generate one with AI, or write your own.
- 3
Run and export
Rows run in chunks of 20 with live progress. Stop any time, retry failed rows, and download a CSV with every answer.
Each row is one evaluation: 1 credit for up to 8,000 characters and 5 questions, 3 credits above that. Failed rows cost nothing.
