Memento

Read full description

Memento is a personal second-memory for your iPhone. Capture a thought in a voice note, a photo, or a line of text — 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. — CAPTURE THE WAY YOUR HANDS ARE FREE — A single composer, bottom-anchored, always ready: • Hold the record pill to speak a memory. Release to save. • Tap the camera well for a quick photo. • Tap the text field to type. Memories save instantly. Tagging, transcription, and AI enrichment happen in the background; you never wait on a spinner. — RECALL IS A QUESTION, NOT A SEARCH — Ask the composer anything: • "what did I buy last Friday?" • "where did I park downtown?" • "that book a friend recommended last month" Memento infers intent — capture vs. recall — and answers with citations to the specific memories you saved. Every answer is grounded in your actual memories. Memento never makes up content. — THE CANVAS IS QUIET — 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 — your brand mark and the primary action. — PRIVACY IS THE PRODUCT — • All AI runs on your device, using Apple's Foundation Models, Speech, Vision, and NaturalLanguage frameworks. • Your voice, photos, text, transcripts, tags, and embeddings never leave your iPhone. • No account. No sign-in. • No analytics, no tracking, no advertising SDKs. • No Memento server exists. — REQUIREMENTS — • iOS 26.0 or later. • iPhone 15 Pro or newer for full AI features (Apple Intelligence required). • Older iPhones running iOS 26 run in Degraded Mode: memories still save and browse normally; AI-powered tagging and recall are reduced. — HOW MEMENTO IS DIFFERENT — • Save first, enrich second. A memory is persisted locally before any AI runs. An AI hiccup never costs you a memory. • No mode toggle. One composer for capture and recall. Memento figures out which. • 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.
