RecallBox is an intelligent tool for organizing screenshots, links, and knowledge, designed for anyone who has too many screenshots, scattered information, and trouble finding things when they need them. Quickly collect important information: You can bring everyday content into RecallBox through automatic photo library import, Shortcuts, the Action Button, manual image selection, or by saving web links directly. The app organizes all materials in a timeline, making it easy to look back, browse, and find what you need. AI-powered knowledge cards: With AI, RecallBox can automatically identify key information in screenshots and links, extract titles, tags, summaries, quotes, tables, and structured content, and turn them into searchable, reusable knowledge cards. Meeting schedules from chats, study material screenshots, payment records, delivery updates, travel pages, web articles, and quick ideas can all be transformed from scattered materials into a clear and organized personal knowledge base. Smart to-dos and reminders: For content that includes times, deadlines, meetings, tasks, delivery milestones, or travel details, RecallBox can intelligently generate reminders and supports local notifications, system Reminders, and Calendar integration. Important items are grouped by Today, Overdue, and the next 7 days, helping you follow up on time without relying entirely on memory. Efficient search and long-term management: RecallBox also supports full-text search, tag organization, favorites, archiving, iCloud sync, and cleanup of processed screenshots. You can keep the knowledge content while removing the original screenshots from your system photo library, making information easier to find, your photo library cleaner, and everyday organization simpler. Give your screenshots, links, and temporary information to RecallBox, and turn scattered content into structured knowledge that is searchable, remindable, and manageable.
