About

Second Brain Vault

Features

Second Brain Vault isn't another folder-organizing app. You just save — the on-device AI files it for you and finds it back later when you ask in plain language. A private memory vault that lives entirely on your iPhone. We're all good at saving. The real question was always "where did I put that?" Second Brain Vault flips the order: you save, the AI organizes and recalls. HOW IT WORKS • Save in one tap — a note, a photo, a voice memo, a PDF, or a web link. Anything, instantly, into your vault. • AI organizes it for you — every saved item gets a title, a summary, a category, and tags, automatically. Photos are read with OCR, voice is transcribed, PDFs and links have their text extracted. • Recall like a person — ask "that real-estate article I read last year," "the best cold-noodle place I saved," "the app idea I jotted last month," and it finds the right memory. It's hybrid retrieval — semantic meaning plus keywords plus recency — so it works even when you don't remember the exact words. • It grows with you — Insights show your top topics and saving trends, and every week the AI writes a short Retrospective of what you saved. The more you save, the higher your Brain Level. WHAT'S INSIDE • Home — today's and recent items, plus a one-line AI insight • Quick capture — five kinds: note, photo, audio, PDF, link • Natural-language Recall — hybrid semantic + keyword + recency ranking • Insights — top topics, save volume, Brain Level growth • Weekly Retrospective — an AI recap of your week of memories • Automatic categories & tags — organized without you filing anything PRIVACY BY CONSTRUCTION Everything is processed on this iPhone. Because it uses Apple's on-device AI (Foundation Models), your notes, photos, voice and documents never leave the device. No account, no server, no ads, no tracking. The only time it uses the internet is to fetch the page of a web link you choose to save. APPLE INTELLIGENCE REQUIRED Auto-organizing, natural-language search, Insights and the Retrospective run on Apple-Intelligence-capable devices. On other devices you can still save and search by keyword; the AI features show an "Apple Intelligence required" state. START FREE, UNLOCK WHEN YOU NEED IT Free: up to 100 items, full on-device AI organizing & search on all 100, every capture type, Insights and Brain Level included. Pro (₩6,600 / year): unlimited saves, iCloud backup & sync, weekly Retrospective history, and more. Lifetime (₩29,000, one-time): everything in Pro, forever, no renewal. You save it; Second Brain Vault remembers it. Drop in your first memory today. ■ Device requirements AI auto-organizing and semantic (meaning-based) search require an Apple Intelligence–capable device — iPhone 15 Pro / 15 Pro Max and iPhone 16/17 or later, iOS 26 or later. On other devices, saving and keyword search still work fully. Everything is processed on-device; nothing is ever sent off your iPhone. ■ Terms of Use (EULA) https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://blue-code.github.io/legal/second-brain-vault/privacy.en.html
