Memento

Memento is a personal second-memory for your iPhone. Capture a thought in a voice note, a photo, or a line of text β€” then ask Memento later and it finds what you saved, with the context you need. Everything happens on your device. Apple Intelligence's on-device Foundation Models framework powers recall, transcription runs through Apple's on-device Speech framework, and scene understanding uses Apple's Vision framework. No account. No server. No network required. Memento works identically in airplane mode. β€” CAPTURE THE WAY YOUR HANDS ARE FREE β€” A single composer, bottom-anchored, always ready: β€’ Hold the record pill to speak a memory. Release to save. β€’ Tap the camera well for a quick photo. β€’ Tap the text field to type. Memories save instantly. Tagging, transcription, and AI enrichment happen in the background; you never wait on a spinner. β€” RECALL IS A QUESTION, NOT A SEARCH β€” Ask the composer anything: β€’ "what did I buy last Friday?" β€’ "where did I park downtown?" β€’ "that book a friend recommended last month" Memento infers intent β€” capture vs. recall β€” and answers with citations to the specific memories you saved. Every answer is grounded in your actual memories. Memento never makes up content. β€” THE CANVAS IS QUIET β€” Memento borrows the quiet confidence of a reading app: a warm paper canvas, a serif hero greeting, hairline borders you barely see. Circular icon wells give every tap target room. Ochre appears only where it means something β€” your brand mark and the primary action. β€” PRIVACY IS THE PRODUCT β€” β€’ All AI runs on your device, using Apple's Foundation Models, Speech, Vision, and NaturalLanguage frameworks. β€’ Your voice, photos, text, transcripts, tags, and embeddings never leave your iPhone. β€’ No account. No sign-in. β€’ No analytics, no tracking, no advertising SDKs. β€’ No Memento server exists. β€” REQUIREMENTS β€” β€’ iOS 26.0 or later. β€’ iPhone 15 Pro or newer for full AI features (Apple Intelligence required). β€’ Older iPhones running iOS 26 run in Degraded Mode: memories still save and browse normally; AI-powered tagging and recall are reduced. β€” HOW MEMENTO IS DIFFERENT β€” β€’ Save first, enrich second. A memory is persisted locally before any AI runs. An AI hiccup never costs you a memory. β€’ No mode toggle. One composer for capture and recall. Memento figures out which. β€’ Grounded answers only. Every recall cites the memory it came from. Nothing invented. Memento is for anyone who has ever walked out of a store thinking "what did the cashier say about returns?", snapped a photo of a book cover and forgotten where they saved it, or told themselves they'd remember the name of that restaurant and didn't. Write your second memory. Keep it on your iPhone.
