DAILY NOTES

Write your day. The rest happens on its own.

The daily note is the way in: one page per day where you just write — and out come the tasks and the knowledge, already organized.

  1. 1

    You write your day

    One page per day: headings, lists, tables, images and files. Drag any block to reorder it.

  2. 2

    AI reads along

    It spots the people, projects and organizations you mention, and flags tasks and milestones.

  3. 3

    The day closes

    On its own, or when you say so. Every detected task is created and lands in your planner.

  4. 4

    It all stays linked

    Each mention links to your Atlas, so your knowledge base builds itself.

Atlas: everything ends up in your knowledge base

Every note leaves links behind. The graph draws them in three layers, from the relation someone declared to the affinity nobody typed.

  • Declared relation Someone stated it: client, team, partner.
  • Wiki link One entity’s article mentions the other.
  • Semantic affinity They keep showing up together in meetings, tasks and docs.

RECAPS

Capture every meeting — audio and screen

secondbrain records your meetings and reads the room. It transcribes live and translates on the fly, and its Screen Comprehension takes snapshots of your screen and understands what’s on it — slides, demos, shared docs. What comes out is a formatted summary and the tasks the meeting left behind.

  • Real-time transcriptionFrom your mic or system audio (Teams, Meet, Zoom)
  • Screen ComprehensionUnderstands slides, demos and shared docs
  • Summaries with your own templatesExecutive, action items, study guide — or the exact format you define
