You save a post meaning to come back to it. You never do. Sift is the place those saves go to stay useful. Share a post into Sift and it gets read, categorized and filed on its own β€” then brought back to you at the moment you'd have forgotten it. SAVE IN TWO TAPS Share a post from your feed straight into Sift with the share sheet. No account, no setup, no typing. Sift pulls in the caption and the thumbnail so the save is recognizable later. SORTED WITHOUT YOU LIFTING A FINGER On-device AI reads each save and puts it in the right category β€” Food, Fitness & Health, Travel, Design, Technology β€” and tags it. Older devices fall back to secure cloud processing, and you're told which one is running. Got it wrong? Change the category once; the correction is remembered. SEARCH THE WAY YOU REMEMBER THINGS "that pasta thing", "the cafe in KadΔ±kΓΆy" β€” search by meaning, not by exact words. It runs on your device, so it works offline and nothing you type leaves your phone. A NUDGE, NOT A NOTIFICATION PILE One end-of-day summary of what you saved. Set a reminder on any single item and Sift brings it back on the day it's useful. YOURS, ON EVERY DEVICE Start anonymously β€” your saves stay on your phone. Sign in with Apple or Google whenever you want backup and sync across devices. Delete your account and everything goes with it, from inside the app. BUILT PRIVATE Categorization is on-device by default. Nothing you save is ever used for advertising, and there's no tracking of any kind. Product analytics are anonymous and can be switched off in Profile β†’ Privacy. Share any link into Sift β€” a post, an article, a video. Instagram links get the richest preview.
