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

You save and bookmark things all day. TikToks you swear you'll try. Screenshots of recipes you'll cook someday. A workout video from three months ago. A meme that made you laugh. A voice memo with a 2am idea. Then you can never find any of it again. The TikTok is buried under four hundred others, the screenshot is lost in your camera roll, the Instagram account goes private, the video gets taken down - and the thing you wanted to keep is just gone. Siftlee is your AI second brain. Save anything you might need later. When you want it back, just ask. And once a month, Siftlee does something no other app does with your saves: it writes you a magazine. THE SIFT - A MAGAZINE, WRITTEN FROM YOUR SAVES On the 1st of each month, Siftlee writes you a magazine about the month you just lived. The recipes you saved come back as real recipe cards. The rabbit holes you fell down become departments. The things you almost bought make the shopping pages, and the ideas worth acting on land in a shortlist at the end. It opens with an editor's letter about your month - because someone finally read all of it. Your issues live on a bookshelf at the top of Spaces. Pull a spine down and read your own month back. Not a member yet? A free sample issue is waiting on your shelf. WHAT YOU CAN SAVE - Videos & posts: TikToks, Instagram Reels & posts, YouTube videos, X posts, articles, blog posts - anything with a URL - Images: screenshots, photos, anything from your camera roll - Audio: voice memos, podcast clips, recordings - Documents: PDFs, Word files, text files Plus: save straight from TikTok, Instagram, Safari, X, YouTube or any app - just tap Share and pick Siftlee. WHAT SIFTLEE DOES WITH IT Siftlee reads, transcribes and understands what you save - including what's said in the videos. It automatically organizes related items into Spaces (broader categories) and Threads (related items within each space) - no folders, no tags, no manual filing. Then you search your entire library in plain English ("what did I save about Sicily?", "that pasta recipe from TikTok") and get an answer with cited sources, not a list of links to dig through. WHEN THE INTERNET DELETES, YOUR LIBRARY DOESN'T Videos get taken down. Accounts go private. Threads get nuked. What Siftlee captured - the meaning, the transcript, the source - stays in your library. X posts are even saved through the official X API, so when the original disappears, your copy survives. WHY IT'S NOT JUST YOUR FAVORITES FOLDER Your TikTok favorites, your camera roll, your bookmarks - that's where saves go to pile up. You can't search them by what's inside, they don't talk to each other, and they vanish when a video does. Siftlee is one library for all of it, searchable by meaning, every save linked to its source. SIFTLEE PREMIUM Try Siftlee free: save anything - TikToks, Instagram Reels, YouTube videos, links, voice memos, documents - with a starter run of saves and searches on the house. Premium removes every limit and delivers The Sift: your own monthly magazine, on the 1st.

Verdict
The clearest difference is in-app purchases: Memento at none against Siftlee's 3. Memento also leads on update cadence (daily vs every 3 weeks). Siftlee's advantage is iOS requirement (17.2 vs 26.0). On price, ads and device support there is nothing between them.
