Screenshots hold articles, conversations, ideas, and things you meant to revisit. Zwind Scrapbook turns those scattered images into a personal journal you can search, read, and share. Scan new screenshots from Photos or choose images to import. The app suggests groups of related screenshots, lets you review each item before saving, and can stitch consecutive images into one long page. You can also skip items you do not want to organize yet, restore skipped groups later, or manually merge related Review items. Saved items stay organized in your Journal for later reading. Text recognition makes screenshot text searchable alongside titles and content. With AI screenshot understanding, recognized text and layout can become a clearer journal page, title, and share excerpt. All Journal pages can be browsed by screenshot date, helping you rediscover old articles, chats, and everyday moments. When something is worth sharing, select a title, excerpt, and image to make a simple share page. You can also export your journal as an Obsidian-friendly ZIP — no worries about data locking. Removing a Journal item does not delete the original photo. Free users get a limited amount of screenshot processing, so you can try it first; Pro supports ongoing development and gives users unlimited screenshot processing plus generous AI credits.
