Will this get my chat account banned, or does it need root?

Neither. It needs no root, no Xposed module, no hooks, and it does not touch the chat app's package, processes, APIs, or account system. It reads what the system accessibility service exposes, the same way a screen reader does.

Can it send a message or touch payments on its own?

No. It fills the input box with ACTION_SET_TEXT and falls back to the clipboard, and never presses send. Transfers, red packets, and payment collection are explicitly out of scope. You press the button.

Where does my chat text actually go?

To the model endpoints you configure in Settings; the author operates no relay server. Screenshots never leave the phone: they go through on-device ML Kit OCR. Chat history storage is off by default, and when enabled it lives in the app's private directory.

Does it still work on WeChat?

No. The WeChat Android build has been withdrawn entirely, with no collection or analysis of WeChat content. Lark works through per-bubble offline OCR because its body text is drawn rather than exposed, and unadapted apps get a one-shot full-screen OCR from the overlay menu.

Which platforms have a jev-chat build?

Android has two editions in this repository, a global WhatsApp preview and a Chinese QQ, Feishu, X and WhatsApp edition. Windows, macOS and iOS each have their own project repository, with the iOS build being the keyboard you compile from source.

What does Jev decide before any reply is written?

It returns the other person's intent, a 1 to 9 danger level, what they want, whether to reply now, and the best action, in about a second. Only then does a separate generation model draft three replies, and Jev ranks them, with the app filling the input box and never tapping send.

How does it read the conversation without touching the chat app?

Through the system accessibility service, the same way a screen reader works, so there is no hook, no Xposed module and no read of the chat app's package, processes, APIs or account system. Lark is handled with on-device ML Kit Chinese OCR because its body text is drawn rather than exposed.

Jev 聊天助手

An Android overlay that reads visible WeChat, QQ, and X conversations through accessibility, asks Jev for intent, danger, and the best action, then drafts three replies and fills one in without ever sending it.

About this project

Read them first, then reply. Before you answer, Jev works out what the other person really means, how risky the moment is and how to respond, then drafts replies you can fill in with one tap. Whether to send is always up to you. English | 简体中文 | Tiếng Việt | Releases. Download · Products · How It Works · Privacy · Community.

Highlights

Jev returns the counterpart's intent, a 1-9 danger level, what they want, whether to reply now, and the best action in about a second.
A generation model drafts three replies and Jev ranks them; the app only fills the input box and never taps send or touches payments.
Reads the screen through the system accessibility service, not hooks or app APIs; Lark uses on-device ML Kit Chinese OCR for its drawn text.
Coverage is author-reported: WeChat 8.0.78 full chain, QQ 9.3.50 group chat, X DMs 12.25 in Chinese; QQ 1v1 and the English X UI are unverified.
Judgment, reply, and vision endpoints are configured separately with presets for OpenRouter, TypeSafe direct, DeepSeek, and Tongyi-compatible APIs.

Quickstart

bash

adb install -r apk/jev-assistant-v1.3-release.apk

Watch out

MIT-licensed and Android 11+ only. Needs accessibility, overlay, and autostart permissions plus your own API key; chat content goes to the model endpoints you configure, and only WeChat, QQ, and X are fully adapted.

Jev at home: voice pipelines, Assist routing, and sentinels

Oct 16, 2026

How Home Assistant conversation agents, macOS voice pipelines, and an advisory sentinel put a fast typed decision in the loop — one call per utterance, thresholds in code, and a daily token budget.

Search visibility, audited by decisions

Oct 16, 2026

Jev-based SEO tools split the crawl from the call: deterministic crawlers count and parse, while typed judgments rank fixes, place internal links, score search results, and track AI-answer mentions — with costs and caveats attached.

Jev on the Gateways: Vercel, Workers AI, and OpenRouter

Oct 12, 2026

The request shape barely changes across surfaces; the surrounding contract does. When to call the API directly and when a gateway, a Worker binding, or a router entry earns its extra hop.
