How it compares

≈MiroThinker sits in the RAG / Knowledge Base category, so it makes more sense to evaluate it alongside tools like mindsdb instead of in isolation.

≈If your main need is closer to "Deep research and information retrieval.", that use case is a better lens for comparison than broad feature checklists alone.

≈MiroThinker uses a MIT license, and community traction are both easier to judge in category context.
