Your mind is for having ideas,
not holding them.
An agentic system that captures, understands, and organizes your thoughts and finances — autonomously.
Stop Being Your Own Filing Clerk
Every day, you manage expenses, capture ideas, and organize notes. Most tools make you do the sorting. Second Brain handles organization. You just capture.
How It Works
Capture
Send a voice memo, type a note, or snap a receipt. Second Brain accepts any input, anytime.
Understand
AI agents analyze your input — extracting meaning, categorizing content, and linking related ideas.
Act
Data is routed to the right place: expenses logged, notes organized, reminders set — all autonomously.
Features
