Memento
Read full descriptionHide 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.

Verdict
The clearest difference is in-app purchases: Memento at none against Box's 1. Memento also leads on update cadence (daily vs weekly). Box's advantage is device support (3 vs 1) and iOS requirement (18.0 vs 26.0). On price and ads there is nothing between them.
