Saved it somewhere. Can't find it now? OPENG brings useful webpages, screenshots, files, and notes into your personal knowledge space. Save in the moment, find things again in your own words, and keep asking questions about the material you have collected. SAVE WITHOUT LOSING YOUR FLOW Use the system share sheet to save links and materials. Take photos, record audio, write notes, or import images and files in the app. After setting up Apple Shortcuts, use Back Tap, the Action Button, or AssistiveTouch where supported by your device for quicker capture. GIVE YOUR MATERIALS A HOME Keep reading excerpts, course materials, work documents, meeting notes, and ideas together. Filter by source and organize with tags. Open content details and available extracted text to revisit the important parts without searching through every app. FORGOT THE TITLE? DESCRIBE IT Try asking, "Where is that AI product design article I saved last week?" Describe the topic or a clue you remember to search materials saved to your cloud library. You do not need the exact title. FIND IT, THEN KEEP GOING Ask follow-up questions, explore key points, and compare ideas using the materials you retrieve. Put past saves to work in your studies, writing, and projects instead of collecting them again and forgetting them. SEE YOUR KNOWLEDGE GROW Review your saved-item count, active days, and activity calendar. See when you added new material and how small moments of saving build up over time. CONNECT YOUR EVERYDAY TOOLS Connect supported cloud drives and Feishu or WeCom bot notification channels. Set conditions and message formats for newly saved content, so matching materials can fit into your existing workflow. Connections require authorization or setup.
