狗头军师 Jev Chat
Chat copilot for Mac, Windows, Android and an iOS keyboard that reads chats, judges with Jev or DeepSeek and drafts replies.
Overview
狗头军师 Jev Chat (Goutou Junshi Jev Chat) is a Chinese chat copilot spun off from the author's earlier Goutou Junshi project. It reads the chat window, analyses the conversation and relationship, and drafts replies, with sending always left to the user. It offers a Mac source preview, a Windows preview zip, an Android debug APK (which cannot capture WeChat) and a new iOS keyboard preview; the Mac window module draws on jev-chat-jarvis-mac.
The iOS keyboard includes local Chinese pinyin typing with about 65,000 entries that works without network access, screenshot-based chat recognition via local Apple Vision OCR or cloud vision models after preview and confirmation, and an analysis step where DeepSeek or Jev judges and DeepSeek or OpenRouter writes replies. Analysis keeps possible intents, confidence, facts versus guesses versus unknowns, next steps, stop conditions, ranked candidates with reasons and costs, and a make-it-sound-more-like-me option; percentages are model estimates, not success rates. The README reports 225 offline checks passing for iOS and notes Windows and Android still need real-device testing. The main body is MIT licensed.
