You saved it. Now read it. SnackBack saves links, videos and images, then lets AI sort, tag and summarize them — and brings a few back to you every day, so you actually read what you saved. SAVE WITH ONE SHARE Share from any app — your browser, Instagram, YouTube, Threads. There is no folder to choose and no tag to type. AI FILES IT FOR YOU The moment something lands, AI reads it, files it into a folder, tags it and writes a summary. You never design a folder structure or keep a tagging system alive. VIDEOS GET WATCHED YouTube videos and Instagram Reels are summarized, so you know what is inside a long one before you give it twenty minutes. IMAGES GET READ Screenshots and carousel posts are read for the text inside them and turned into cards you can search. ASK YOUR LIBRARY "What was that marketing article I saved last week?" finds it. No title, no date, no exact keyword needed. IT COMES BACK TO YOU A few saved items return each day, summarized, in servings small enough to finish. Saving is where every other app stops. This is the part that makes the pile go down. WORKS OFFLINE Saves land straight away without a connection and sync once you are back online. WHO IT IS FOR - You save good posts from Instagram or Threads and never open them again - Links pile up in chat threads where you cannot search them - You started with Notion or Evernote and gave up on the upkeep - Your read-it-later list only ever gets longer SUPPORTED FORMATS Links (URL), images, and text notes. FREE AND PRO Free covers up to 30 saved items in total. Pro removes the cap and adds audio playback, library Q&A, and weekly reports. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed in your App Store account settings.

Verdict
The clearest difference is update cadence: SnackBack at weekly against compost's every 5 months. On price, ads, in-app purchases and device support there is nothing between them.
