SecondBrain Pro vs Second Brain

Save a thought while you walk. Find a decision after a meeting. SecondBrain Pro is a voice-first memory app for iPhone and iPad, with an Apple Watch companion for capture from your wrist. Choose local storage or free iCloud sync. Optional Standard and Premium upgrades are one-time purchases. CAPTURE AND RECALL Record a thought or type a note. Organize ideas, learnings, tasks and decisions with tags. Search saved memories by text and dates, or ask AI Chat about your memories when a supported AI provider is available. START FREE Voice and text capture, ordinary search, local storage and iCloud sync are included in Free. On-device AI chat is available on supported Apple Intelligence devices. No SecondBrain account is required. iCloud needs your Apple account and available iCloud storage. STANDARD: OPTIONAL ONE-TIME UPGRADE Add premium speech playback voices, expanded memory context, JSON/Markdown export, and backup and restore tools. iCloud sync is already included in Free. PREMIUM: YOUR OWN BACKEND AND MCP Includes Standard capabilities and adds a connection to your own Cloudflare Worker backend, backend semantic search, API access and MCP integration for compatible tools such as Claude Code and Cursor. This option requires your own Cloudflare account, deployed backend URL and API key. MCP also requires a bridge and compatible client. Cloudflare usage may incur separate charges. Local-only memories are not automatically available to external assistants. WHERE YOUR DATA GOES Local Only stores memories on this device. iCloud sync transfers them through your personal Apple iCloud account. The optional Cloudflare mode sends memories to your configured backend for storage and selected AI processing. Connected MCP clients handle data according to their own configuration and provider policies. Voice capture uses Apple's speech recognition and may use Apple servers. Microphone and speech recognition permission are required. Location context is optional. The app requests in-app consent for AI processing. AI REQUIREMENTS On-device AI chat uses Apple Foundation Models and requires iOS 26 or later, compatible Apple Intelligence hardware, Apple Intelligence enabled and an available model. Voice capture and ordinary search do not depend on Foundation Models. Premium users can configure cloud AI through their own backend. Check the App Store compatibility section before installing. PRICING Free download. Standard and Premium are optional one-time in-app purchases, with no SecondBrain subscription. See the purchase sheet for your regional price and currency. External backend services are separate. Developed in Switzerland by Heinrich Krupp. Product facts: https://secondbrain-pro.netlify.app/facts Support: https://secondbrain-pro.netlify.app/support

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.
