Most notes get written once and never read again. Second Brain reads them for you. Write a line whenever something is on your mind, and once a week it tells you what your week was really about. You don't need to keep a diary or a streak. One line a day is enough. YOUR WEEK, READ BACK TO YOU The weekly insight covers what took up your attention, what changed since last week, and one concrete thing to try. Every insight shows the notes it came from, so you can check it against what you actually wrote. Your first weekly insight is free. Once a month you get a longer read on where the month went. After your first five notes there's also a first impression of you, and it fills in as you keep writing. CAPTURE Type, or press and hold to speak. Share text, links or images from other apps, or pick screenshots and the text in them is read on your phone. Each note gets a title and tags automatically, so there's nothing to file. ASK YOUR PAST Explore searches by meaning, not only keywords. Ask "What did I decide about the move?" or "What did Anna say last time?" and get an answer built from your own notes. PEOPLE Keep a card for the people in your life: what they said, what you did together, what to bring up next time. Before you meet someone, a reminder shows your open to-dos and what you talked about last time. REMINDERS AND WIDGETS Write "dentist next Friday at 3pm" and it becomes a reminder and a checklist item. There are widgets for the Home Screen and Lock Screen, and the checklist can run as a Live Activity. PRIVACY Your notes are stored on your device. There's no account to create and no server of mine in between. To title, tag and reflect on your notes, their text is sent to a cloud AI service. If your iPhone supports Apple Intelligence, you can turn on On-Device AI and new notes are handled on the phone instead; Explore and reflections still use the cloud. Every AI result is labeled "On device" or "Cloud AI", so you can see which is which. iCloud sync is optional and uses your own iCloud account. You can export everything as JSON or Markdown at any time, for free. FREE AND PRO Free: 5 notes a day, daily reflections, your first weekly insight, and export. Pro: unlimited notes, weekly insights and monthly reads, 20 Explore questions a day, up to 30 screenshot imports a day, unlimited people, the memory graph and life themes, iCloud sync, and the Rainbow Aurora theme. Pro is a monthly or yearly subscription. The yearly plan comes with a 7-day free trial, the monthly plan with 3 days. Payment is charged to your Apple ID and renews automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel it in your App Store account settings. Second Brain is made by one person, Lemon. Terms of Use: https://smartkiitos.com/secondbrain/terms/ Privacy Policy: https://smartkiitos.com/secondbrain/privacy/
