Capture a thought in one tap. Brain Map titles, tags and files it into the right project on your iPhone. Share projects with family, ask your notes. Free, no account. Brain Map is a free, private second brain for your iPhone. Capture a thought in one tap, by typing, talking, snapping a photo 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 floating capture button on every tab: tap to write, touch and hold for voice, photo or link • Prefer a capture bar, a tab or nothing on screen at all? Pick your style in Settings • Voice notes of any length, transcribed on your iPhone • Snap a whiteboard, a page or a receipt: the text in the photo becomes searchable • Paste or share a link from Safari or any app, with its title and preview • Capture from Home Screen and Lock Screen widgets, Control Center, the Action button and Siri ("Add a note to Brain Map") 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 what matters, filter by tag, set a reminder on any note 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") and picks up the due date • Turn any note into a task, tick it off and watch the project's progress • Ask about a project and get answers from its notes SHARE WITH FRIENDS AND FAMILY • Share a project or a single note with a link; they open it in Brain Map • Choose who can make changes and who can only view; everyone sees updates as they happen • iCloud sync keeps your notes up to date on every iPhone you use CALENDAR, IF YOU WANT IT • Show task and project due dates in a separate Brain Map calendar; your other calendars are never changed • Taking notes in a meeting? Link them to the meeting you're in with one tap • Add any task to your calendar in one tap SEE HOW YOUR IDEAS CONNECT • A living map of your notes, clustered by topic, with your projects as hubs • Tap a note to open it, or focus the map around it to see its neighbourhood • Brain Map suggests links between related notes; keep the good ones, dismiss the rest • Related notes appear under every note you read 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" • Works across English, Russian and Ukrainian notes ASK YOUR NOTES • Type or say a question and get the notes that answer it • On iPhones with Apple Intelligence, get a written answer that cites the notes it came from FROM YOUR PAST • Old ideas come back when they're useful: a "From your past" card and widget resurface notes you'd forgotten PRIVATE BY DESIGN • No account, no ads, no tracking, no analytics • All the AI runs on your iPhone: speech, text in photos, tags, projects, 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 • Shared projects and notes go through iCloud to the people you invite, and no one else • Export everything as Markdown or JSON whenever you like 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, and written answers need an iPhone with Apple Intelligence; everything else works on any iPhone that runs iOS 26.
