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/

One place for everything you know. Memoral is a private, encrypted personal wiki for the pieces of your life that get scattered: journal entries, medical notes, recipes, people, places, projects, books, ideas and everyday moments. Write naturally. Memoral connects the rest. Use Memoral to keep: • Daily journals and reflections • Symptoms, medications and doctor visits • Family recipes and meal plans • Places, restaurants and trips • Books, highlights and course notes • Projects, decisions and goals • People, events and family details • Ideas you want to come back to Memoral turns your entries into a connected wiki. It can detect wiki-links, suggest tags, find related entries and help you search by keyword, meaning, tag, date or plain-language question. Ask things like: “What was that tonkotsu spot in Tokyo?” “When did I first write about this symptom?” “What recipes did we cook for Dad’s birthday?” “What notes mention the book that changed my mind?” Each answer is grounded in your own entries, so your wiki becomes useful not just for you, but for the AI tools you already use. Private by design: • Encrypted by default • Per-entry envelope keys • Entries are never used to train models • Export your wiki in Markdown or JSON on paid plans • Passkeys and 2FA supported A plain privacy note: Memoral is encrypted at rest, but it is not zero-knowledge or end-to-end encrypted. AI features run server-side, so relevant text may be processed by model providers when you ask Memoral to connect, summarize or answer questions about your wiki. Memoral is for personal notes and memory. It does not provide medical, financial or legal advice.
