What it is
Google Sheets custom functions that let you classify, tag, and score text by asking plain-language questions in a formula. Answers come from TypeSafe's Jev model as real values your sheet can use.
How it uses Jev
Jev answers a Noul, Choice, or Score question per cell. The sheet formula applies the threshold or minimum confidence and returns TRUE/FALSE, one of your categories, a number, or UNSURE below it.
Primitives:choicescorenoul
Technique worth stealing
Whole columns fill one answer per cell; several columns judge each row as one item.
Try it
Install via Google Workspace Marketplace, download a release, or build from source.
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.
