AFFiNE AI second brain

AI second brain for personal knowledge management

Build an AI second brain that connects notes, PDFs, transcripts, and ideas into searchable knowledge you can keep refining.

How to use AI second brain in AFFiNE

  1. 1

    Capture the source material

    Paste or draft notes, tasks, sources, ideas, and project context in an AFFiNE doc so the AI starts from context you can inspect, edit, and cite.

  2. 2

    Ask for structure before polish

    Generate linked knowledge, reusable summaries, maps, and review systems with clear sections, reasoning, and next steps instead of a one-line answer that is hard to verify.

  3. 3

    Save, link, and improve

    Keep the AI second brain result as editable AFFiNE blocks, link it to related notes, and revise it as your understanding changes.

Why AFFiNE is a better AI workspace

Docs and whiteboards work together

Move between structured writing and edgeless visual thinking when a problem needs both a clear narrative and a spatial map.

Useful boundaries are explicit

Each workflow explains what AFFiNE can support today and where you should still review, cite, or prepare source material yourself.

Built for responsible knowledge work

  1. Local-first workspace

    AFFiNE is designed around local-first knowledge work, so your notes stay under your control unless you choose to sync.

  2. Editable, reusable results

    AI output is not locked inside a disposable chat. It becomes part of your documents, whiteboards, and knowledge graph.

  3. Free to start

    Start with AFFiNE Free, then compare Pro and AI plans when your workflow needs more capacity.

Use it as an assistant, not an autopilot

An AI second brain only works if you curate it. Review imported content, link related ideas deliberately, and delete noise instead of collecting everything.
