Paste a chat with your crush from WeChat, WhatsApp, QQ or iMessage. Every message gets emotion and intent tags with reasons, your replies get graded with better rewrites, and key moments land on a timeline. Works with the original Jev model by TypeSafe AI, or DeepSeek and any OpenAI-compatible model. Open source, runs locally, cents per chat.
