Second Brain Map

Private AI notes & voice memos

Only for iPhone

Free

iPhone

New in 1.1: scan documents, link your notes, record meetings with a transcript, lock notes with Face ID and export PDFs. Free, private, AI on your iPhone. Brain Map is a free, private second brain for your iPhone. Capture a thought in one tap, by typing, talking, snapping a photo, scanning a document or sharing a link, and Brain Map gives it a title, tags it, files it into the right project and connects it to what you already know. Find anything by meaning, see how your ideas connect on a living map, and ask your notes questions. All the AI runs on your iPhone: no account, no subscription, no limits. CAPTURE ANYTHING IN ONE TAP • A capture button on every tab: tap to write, touch and hold for voice, photo or link (or pick a capture bar or tab in Settings) • Voice notes of any length, transcribed on your iPhone • Scan documents into searchable PDFs; snap a whiteboard or a receipt and its text, labels and QR codes become searchable • Attach PDFs and files: their text is searchable too • Share links and files from Safari or any app • Capture from widgets, Control Center, the Action button and Siri WRITE YOUR WAY • Headings, lists and checklists you tick right in the note, with Apple Writing Tools • Templates for meetings, journals and project briefs, or your own, from the / menu • Link notes, projects and days with @ and see which notes link back MEETING NOTES • Record a meeting of up to three hours, even with the screen locked, with a Live Activity • A timestamped transcript and moments you mark; tap a time to hear that part again • With Apple Intelligence: a summary, decisions and action items that become tasks IT ORGANISES ITSELF • Every note gets a title, tags and a short summary, made on your iPhone • Notes it isn't sure about wait in the Inbox for a one-tap confirm • Undo anything with one tap; pin, filter by tag, set reminders • "From your past" brings back notes you'd forgotten PROJECTS THAT FILL THEMSELVES • A project is just a name: add an emoji and a due date if you like • New notes file themselves into the right project; when Brain Map isn't sure, it suggests and you decide • It spots to-dos in your notes ("call the bank on Friday") with their due dates • Tick off tasks, watch the progress, and show due dates in a separate Brain Map calendar SHARE WITH FRIENDS AND FAMILY • Share a project or a note with a link; choose who can edit and who can only view • iCloud sync keeps your notes up to date on every iPhone you use SEE HOW YOUR IDEAS CONNECT • A living map of your notes, clustered by topic, with your projects as hubs • Brain Map suggests links between related notes; keep the good ones, dismiss the rest FIND ANYTHING BY MEANING • Search for what you meant, not the exact words: "that pricing idea" finds "try a free tier with a tip jar" • Your notes in iPhone search (Spotlight), if you want them there • Works across English, Russian and Ukrainian notes ASK YOUR NOTES • Type or say a question and get the notes that answer it • With Apple Intelligence, a written answer that cites its notes PRIVATE BY DESIGN • No account, no ads, no tracking, no analytics • All the AI runs on your iPhone: speech, text in photos and scans, tags, links, search and answers • Your notes stay on your device and, if you turn on sync, in your own private iCloud. There is no Brain Map server, and we never see your notes • Lock any note with Face ID: it's encrypted on your iPhone and in iCloud, and stays out of search, widgets and Spotlight • Export everything as Markdown, or a note or a whole project as a PDF FREE, FOR REAL • No subscription, no trial, no daily caps, no limits on notes or projects • In English, Russian and Ukrainian Brain Map works offline. Sync and sharing need iCloud; summaries and written answers need an iPhone with Apple Intelligence. Everything else works on any iPhone with iOS 26.
