What it does PureChat is a full-stack chat application built on Vue 3, Vite 6, and Electron. It uses Tencent’s IM SDK for real-time messaging, then layers AI chat on top via pluggable providers—OpenAI, Ollama, DeepSeek, and a few affiliate-linked API aggregators. You get Markdown rendering, code highlighting, dark mode, chat-to-screenshot export, and both web and desktop builds.

The interesting bit The project treats AI as a parallel channel to human chat rather than a replacement. Same account, same interface, two backends: Tencent IM for people, OpenAI/Ollama for bots. The README is admirably blunt about requiring three separate environment variables just to boot—API key, Tencent SDK app ID, and your own server URL—so this is not a “clone and go” weekend project.

Key highlights

• Multi-model AI support with streaming, web search, and “deep thinking” mode
• Chat-to-screenshot generation with one-click copy
• Desktop builds for Windows (.exe) and macOS (.dmg) via Electron
• Theme switching tied to system preference
• WangEditor 5 integration for rich text input
• Deploy-ready for Vercel with documented environment variable setup

Caveats

• Several required env vars are marked “必选” (required) with no defaults; misconfigure one and the app likely hard-fails
• The model provider table includes affiliate referral links, which is fine but worth noting for the suspicious
• README claims “modular architecture” and “scalable AI integration” without showing the module boundaries—take it as aspiration, not evidence

Verdict Worth a look if you need a Chinese-market chat client with AI sidecar functionality and don’t mind wiring up Tencent cloud credentials. Skip it if you want a self-contained, backend-optional AI chat UI.
