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.

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
