welink

WeLink is a WeChat chat data analysis platform that visualizes your chat history with detailed statistics, sentiment analysis, and time-based insights. It supports friend analysis, group chat analysis, global search, and privacy shielding, all running locally on your machine. The platform also provides an MCP server for querying data via natural language using Claude Code.

welink sits in the Dev Tooling category, so it is usually better judged by workflow fit, deployment style, and team needs than by isolated features alone. Based on the available metadata, it leans most clearly toward Friend analysis with detailed stats, trends, word clouds, and sentiment analysis. A representative use case is Analyze personal social relationships and chat patterns. The listed license is AGPL-3.0. GitHub stars are currently 300. Relevant tags include chat-analysis, chat-history.
