- Jev operates on Android (ARM 64 and above with 11 or higher), Windows (version 10 1903 or above), and macOS (Apple Silicon 13 or newer). It reads on-screen conversations to determine the other party's intent and risk level, suggesting 3 possible replies.
- The app does not modify or hack chat software; instead, it uses system Accessibility services to read displayed conversation content. Replies are not sent automatically but are reflected in the user's input box.
- It locally stores contacts, notes, and optional conversation history for analysis and allows custom configuration by registering separate AI API keys for judgement, replying, and screen recognition (visual) functions.
- Supported apps include QQ (Android 9.3.50 version), X (Twitter DM) with Korean interface, and 飞书 (Lark). Unsupported apps can be analyzed manually through screen OCR. The Android WeChat version is not supported.
It's interesting that Jev scrapes screens automatically across different chat apps and even uses OCR when text isn't visible. However, it's important to note that on ROMs like Xiaomi or HyperOS, background restrictions might cause unstable functionality. Also, since users need to manage AI API keys themselves, they must carefully consider both costs and privacy management before using it in practice.
