A note-taking app that remembers for you
Second Brain Box is a private note-taking app that brings your notes, daily journal, projects and ideas together in one place.
Notes and ideas
Write fast, link notes by typing [[name]] and see the connections in the graph view.
Voice capture
Dictate a thought on your phone or Apple Watch – it is saved as text.
Daily journal
Every day gets its own entry that saves itself as you type. In the evening the AI adds a short summary of the day.
Projects and tasks
Task board, priorities and deadlines in the same place as your notes.
Ask the AI
Ask about your own notes and journal and get answers with sources.
Take your data with you
Download all your notes as Markdown files at any time.
Your notes are yours alone
No other user can see your data – not even the administrator. The AI never changes anything without your approval.
