Your day sorts itself out.

From thought to follow-through
One sentence can contain more than one job.
Second Brain separates the intents, finds where each one belongs, and gives you a receipt instead of a vague AI answer.
You say
Dinner with Anna on Friday at 7, and remind me to buy flowers before that.

Friday afternoon
Nothing is hidden. Review every change before it becomes part of your day.
Capture naturally
Speak, type, share a link, or send a file. Do it before the thought disappears.
Review the plan
See each project, page, reminder, and event as a separate result. Fix only what needs attention.
Keep using your tools
Tasks live in Reminders. Dates live in Calendar. Context stays in your Markdown pages.
Inside the app

Capture
Get it out of your head.
