Second Brain - AI Assistant
Everything in One Place
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Your brain was built to think, not to remember.
SecondBrain turns any spoken thought into a filed, titled, dated record in about three seconds. No folders. No tagging. No deciding where it goes.
Just talk. Your second brain does the rest.
SUBSCRIPTION REQUIRED
Second Brain requires an auto-renewable subscription ($7.99 per week or $29.99 per month). Every feature described below is included with an active subscription - there are no extra purchases.
HOW IT WORKS
Hold the button and say what's on your mind - in the car, on a walk, halfway out the door. SecondBrain transcribes it, works out what you meant, and files it in the right project with the right due date. Then it buzzes back to confirm.
"Call the accountant next Friday about the trust" becomes a task, in Client Work, due Friday. You never picked a project. You never set a date.
EVERYTHING IN ONE PLACE
• Today - your daily brief, what's due, and what's coming up next
• Tasks - organized by project and due date, automatically
• Calendar - tasks and events together in one month view
• Brain - every note, photo, link and file you've ever captured
• Projects - see what's active and what's gone quiet
CAPTURE ANYTHING
Voice, typed notes, photos, links, files. It all lands in the same place and gets sorted for you. Anything the app isn't confident about goes to a review inbox instead of being filed wrong - so nothing is ever lost or buried in the wrong folder.
ASK YOUR BRAIN
Get answers from everything you've captured. Your notes stop being a graveyard and start being something you can actually use.
PRIVATE BY DESIGN
Your content lives in a private database. Nothing is shared, nothing is public, and your notes are never sold or used to train AI models. Export or delete everything at any time.
SUBSCRIPTION
SecondBrain requires a SecondBrain Pro subscription - $7.99/week or $29.99/month. All features shown, including voice capture, AI filing, the Daily Brief, and instant search, are part of Pro. Payment is charged to your Apple ID; subscriptions auto-renew unless cancelled at least 24 hours before the period ends. Manage or cancel anytime in your Apple Account settings.
