Your AI voice note app and AI journal in one. Talk the way you think, and Thinkdown turns it into a clear note or a journal entry that sounds like you. Tap record and just talk: half sentences, tangents, "wait, no". Thinkdown transcribes it and writes a clean note in the style you pick, with a title and tags. Your recording and transcript stay with the note, so you can always check what you really said. AI JOURNAL • Talk through your day and get a journal entry in your own voice, not a summary. • Your journal entries show the photos and videos you took that day, read on your device only. • A daily streak and milestones keep the habit going. • Ask your journal anything, like "what was I worried about last month?", and get an answer from your own entries with the sources it used. • Places on each entry, and a map of all your notes. • The events from your calendars that day show inside the note. IT KNOWS YOU • The more you talk, the better it knows you. Every note suggests the people, places and words it heard; one tap saves them to Memory, and from then on they're spelled right. • It fixes itself. Select a word it got wrong, tap Fix and say what you meant. The note updates and Thinkdown remembers how it misheard you, so it doesn't happen again. • It knows where you are. Neighborhood and town names near where you record help it spell local places right. • Add documents as background, so notes about a project get its names and references right. SAY IT YOUR WAY • Record on iPhone from the app, the Lock Screen or Siri, on the Mac with a keyboard shortcut, or on Apple Watch. • Pause and pick up again, or add more to a note later. • 21 voice languages, and you can mix them in one note. READ IT CLEAN • Styles turn the same thought into a clear note, a journal entry, a list, an email or a prompt for an AI assistant. Make your own, too. • Rewrite any note at any time, with every earlier version kept. • Combine several notes into one. • Connect Claude, ChatGPT or another AI app to your notes from Settings > AI apps. • Import notes from other apps on the Mac. MAKE IT YOURS • Choose the colors you like, in light or dark. ON ALL YOUR DEVICES • Notes sync between iPhone, iPad, Mac and the web, and you can read your latest notes on Apple Watch. • Everything works offline and catches up when you're back online. • Tags, pins, search and a 30-day Deleted page. PRIVATE BY DESIGN • Sign in with Apple or a code sent to your email. No passwords. • Lock Thinkdown with Face ID, Touch ID or your passcode if you like. • No ads, no tracking, and your notes are never used to train AI models. • Delete your account and all of its data from Settings at any time.
