What it is
A browser-based extraction aid for systematic reviewers. Open a trial report and its supplements, ask your extraction form or a RoB 2, ROBINS-I, QUADAS-2 or TIDieR template, and get verbatim quotes with file and page for human checking.
How it uses Jev
Jev answers typed questions with probabilities and only points at line ids; code copies the quote out of the file. A screening Choice picks which line answers a question, then a verifying Noul asks whether that line itself answers it. Quotes with Noul ≥ 0.5 are kept, adjacent lines merged, table labels added.

Technique worth stealing
Speculative fan-out: one screening request carries every question against the same text, so an 18-question template costs about a cent and five seconds over three files.
Try it
Use it at jevreviewer.xera.ac or choxos.github.io/jev-reviewer. No key, no install.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
