How many pages are still sitting in your read later pile? AI Bookmark is a read it later app built so that pile stops growing. Save a link with one tap from the share sheet, and AI writes a summary and files it into a category for you. Because the summaries are searchable too, you can find a page again even when you only half-remember it. โ–  Know what is in it without reading it AI summarizes long articles, so you can decide whether something is worth your time before you open it. Read the full page only when it earns it. You can also filter the list down to unread items. โ–  Find it from a vague memory You save something useful, and later you cannot find it. It happens to me constantly. AI Bookmark searches summaries as well as titles, so "I think it was about React" is usually enough to get you back to the page. โ–  Organized without organizing Saved sites are sorted into categories automatically. No folders to create, no tags to decide on. Throw in anything that catches your eye and it turns into a personal reference you can actually browse. โ–  Ask the AI about an article When a summary is not enough, ask questions about the article itself. Get to "so what should I do" without rereading the whole thing. โ–  How it works 1. Open a page in Safari or any browser 2. Tap the share button and choose AI Bookmark 3. AI handles the summary and the category You can also paste a URL directly inside the app. โ–  Pricing Saving, organizing, and searching bookmarks is free and unlimited. AI summaries and article chat come with a free allowance. When it runs out you can still save links without a summary. If you want more, Premium gives you 200 AI uses per month, monthly or yearly.
