## Second Brain Description
The AI-powered journal that remembers everything. Capture thoughts by voice or text — AI organizes, connects, and recalls your memories so nothing is ever lost.

Second Brain models how your mind actually works. Every memory is classified into three layers — instant thoughts, short-term plans, and long-term knowledge — then linked, reflected on, and surfaced exactly when you need it.

CAPTURE IN SECONDS

Type a thought or press and hold to speak. AI automatically classifies each memory, extracts tags, and generates a summary. No folders. No manual sorting. Just capture and move on.

EXPLORE YOUR MEMORIES

Ask anything: "What did I decide about the project?" or "What did Sarah say last week?" AI searches across all your memories using meaning — not just keywords — and weaves relevant ones into a clear, contextualized answer.

PEOPLE MEMORY

Create cards for the people in your life. Track what they said, shared experiences, meeting notes, and to-dos. Never forget a birthday, a promise, or a conversation again.

WEEKLY REFLECTIONS

Every week, AI reviews your memories, finds recurring themes, spots growth areas, and offers a concrete suggestion — like a thoughtful friend reading your journal.

DISCOVER CONNECTIONS

AI builds a knowledge graph across your memories, revealing patterns and links you never noticed. Watch your ideas form constellations over time.

VOICE CAPTURE

Press and hold to speak. Real-time transcription fills your memory instantly. Switch between English and Chinese with one tap. Perfect for capturing thoughts on the go.
