Second Brain vs AI Note Taker

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.

Turn scattered thoughts and spoken ideas into a private, searchable memory. Capture what matters, ask questions of your own notes, and take only the context you choose into another AI. CAPTURE BEFORE IT DISAPPEARS Write a note, share text into the app, or record a voice memo. A recording you start can continue while the app is in the background, so you can finish the thought without keeping the screen open. Add a reminder in everyday language when something needs to come back at the right time. VOICE MEMOS BECOME SEARCHABLE Record and play voice memos, then turn speech into text with on-device transcription. The resulting note joins the same private search as everything you type. Recording never begins by itself. ASK YOUR NOTES, CHECK THE SOURCE Ask a question in plain language. Answers are grounded in your saved notes and show the supporting source, so you can inspect the original words. When matching evidence is limited, the app clearly signals that limitation. TAKE YOUR CONTEXT ANYWHERE Enter the question you want to ask another AI. Review the relevant facts found in your notes, remove anything you do not want to include, then copy or share a clean context-and-question prompt. Nothing is sent automatically; you choose the context and destination. PRIVATE BY DESIGN AI processing runs on your device. No account or tracking is required. Notes stay local by default. Optional private iCloud sync is off until you enable it, and voice recordings remain local to the device. After any required model download, core AI features can work offline. SUBSCRIPTION AND ARCHIVE MODE Second Brain offers monthly and yearly auto-renewable subscriptions. Eligible new subscribers may receive a 3-day free trial. Without an active subscription, creating new notes, recordings, imports, or AI output is blocked. Your previously saved notes remain readable and searchable, recordings remain playable, and existing items can still be deleted. PORTABLE EXPORTS Export note text and Ask history as Markdown or structured JSON. Recording audio files are not included, so these exports are portable records rather than a complete app backup. Existing export remains available in archive mode. REQUIREMENTS Requires iOS or iPadOS 26 or later. Devices with Apple Intelligence use Apple's built-in on-device model. Other supported devices may need a one-time model download. A Studio AM app. Made in San Francisco.
