What it is
An Android accessibility overlay for WeChat, QQ, and X chats. It reads visible messages, judges the other party's intent and risk, drafts three replies, and fills a chosen one into the input box without sending. For personal study and research.
How it uses Jev
Jev answers one batch of typed questions (about seven) on the captured recent messages: the other party's true intent, danger level (1-9), what they want, whether to reply now, and the best action, returning in about one second with confidence. Jev also ranks the three drafted replies by suitability with proportions.

Technique worth stealing
One core plus a per-app ChatAppAdapter that turns the accessibility tree into title and messages; everything downstream is reused.
Try it
adb install -r apk/jev-assistant-v1.2-release.apk, then set an OpenRouter API key and enable permissions.
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.
