About
IMA Knowledge Base is Tencent's AI-powered knowledge management product, often called an AI 'second brain'. It lets you create personal or team knowledge bases, upload documents in common formats (PDF, Word, PPT, Excel, TXT), and run retrieval-augmented Q&A — the AI answers only from your own materials, dramatically reducing hallucinations on personalized or company-specific topics. Beyond standalone use, IMA shines through its integration ecosystem: it connects to WorkBuddy as a native connector (authorize once, then add the 'Based on IMA Knowledge Base' prefix to force document-grounded answers), and it exposes an OpenAPI at ima.qq.com/agent-interface where you can obtain a Client ID and API Key. With the API configured, you can build a bidirectional closed loop — retrieve from the knowledge base, have the AI process and generate (meeting minutes, reports, summaries), and automatically save the output back as new IMA notes. IMA also complements a broader Tencent ecosystem (Feishu, Tencent Docs, Lexiang, Tencent Meeting) via WorkBuddy's connector hub. For Chinese users who want a private, growing knowledge layer for their AI assistants without touching RAG infrastructure, IMA Knowledge Base is the most practical option available.
