得到大脑

得到大脑, previously known as Get Notes, is an AI-assisted note-taking and personal knowledge management product from the Chinese learning platform 得到. It is built around the IDEa of a "SECond brain": a place where quick thoughts, voice mEMOs, images, links, and reading notes can be captured and then made more useful with the help of an AI assistant. The web veRSIon sits alongside mobile apps and a WeChat mini-program, with content syncing across devices so users can pick up where they left off.

What it does

The product combines Lightweight capture with AI-driven review and writing support. Users can save text notes, dictate ideas by voice, and bring in content from images and web links, as well as import material from services such as the 得到 APP, Wechat Reading, and Flomo. Notes can be tagged Intelligently and searched by keyword, date, or source, which helps turn a scattered collection of snippets into something closer to a searchable Personal library.

Key capabilities

• Flexible capture: text, voice, image, and link-based quick notes, plus imports from several external sources.
• smart organization: automatic tagging and multi-filter search to locate notes quickly.
• cross-device sync: edits made on the Web ARe reflected in the app and mini-program.
• AI note assistant: a built-in helper that reads and analyzes the user's notes and answers questions about them.
• Four AI ACTions: described as sprouting new associations from a single line, commenting on strengths, polishing rough phrASIng into finished writing, and challenging weak logic.
• content repurposing: turning a small idea into shareable fORMats such as social posts or image cards, with one-click generation of long or multi-image cards.
• knowledge bases: topic-based personal collections and shared team Knowledge Bases, with the option to subscribe to other people's public collections.

Who it is for

得到大脑 is aimed at people who take frequent notes and want help turning them into finished material: writers, students, researchers, content creators, and knowledge workers who collect ideas across devices. Small teams may also find the shared knowledge base useful for collective notes and reference material. Because the interface and content are primarily in Simplified Chinese, it is most practical for Chinese-speaking users.
