SecondBrain: AI Memory

Most of what you hear, think and plan today is gone by tomorrow.
Speak your mind. SecondBrain writes it down, gives it a title, and files it for you.
No folders to manage. No typing. Just talk, and your thoughts organize themselves.
The AI note app for people who think out loud.

WHY SECONDBRAIN
• Capture in seconds: speak, type, or share a thought and it is saved instantly
• Zero organizing: AI transcribes, titles, and files every note into a self-building folder tree
• Voice to schedule: say "dentist Tuesday 4pm" and it creates real events in Calendar and Reminders
• Morning briefing: wake up to a daily summary of your day and what matters
• Ask your brain: chat with your notes and get answers from everything you have saved
• Brain graph: explore your ideas as a living 3D map of connected notes
• Search everything: full-text search finds any note in an instant
• Share from anywhere: send text, links, images, or audio from any app into SecondBrain
• 20+ languages: speak in your language and get replies in your language

Founder juggling clients, student capturing lectures, or just someone with too many thoughts to hold? SecondBrain is the frictionless place to put them all. Brain-dump on the go and let the AI do the filing.
