New Quello

Quello is a "second brain"-style knowledge workspace that connects sources like Notion, GitHub, Google Drive, and local PDFs, then lets you ask questions in natural language, with voice support too.

Its standout feature is that every answer comes with evidence links—one click takes you to the original passage. If something isn’t in the materials, it won’t make it up. It’s ideal for content creators, product teams, and engineering teams that need to write based on their own documents—for example, summarizing weekly reports, comparing API versions, and organizing roadmaps. It also offers a canvas-style writing area and an MCP Server interface.

There’s a free version you can try first. The official website doesn’t specify how well it retrieves Chinese-language materials, so before using it, you can test it with your own documents.
