What it is
Tab Sorter is a Chrome MV3 extension that groups every tab in the current window into named, colored Chrome tab groups with one click. It offers a rules engine (Jev) for fixed groups and an optional LLM engine that invents group names, for daily cleanup or exploration.
How it uses Jev
Jev classifies each tab by answering one Choice question per tab, in parallel, against user-editable group criteria. The result assigns tabs to named groups; unclassified tabs fall to a fixed fallback bucket. Manual groups are untouched, and the pre-grouping tab order is restored on ungroup.
Primitives:choice
Technique worth stealing
Parallel typed Choice questions per tab against editable criteria, with fallback bucket and order restoration.
Try it
Load unpacked from source or release zip; configure Jev key and group rules in options.
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.
