Your family's memory, one question away. CRTX is the memory you share with the people you live with. Save voice notes, photos, links, PDFs, and audio files. Then ask a question in plain English and get the answer back across everything anyone in your pool has saved. WHAT YOU CAN DO • Capture anything. Type a thought, paste a link, hold to record a voice note, drop a PDF, snap a photo of a flyer or receipt. CRTX reads what's inside, so you can search the contents — not just the filename. • Ask anything. "What did the doctor say?" "Where's the school calendar?" "What did Sarah send about Friday?" CRTX finds it in seconds and shows you the source. • Pool with the people you share a life with. Your personal pool stays private. Shared pools are for the people you're in this with — partner, kids, siblings, your closest friends. • Tasks, on their own or tied to something you saved. Assignable in shared pools. Recurring. Reminders before, at, and after the deadline. • People show up automatically. CRTX recognizes names in what you save and ties items to the right person. Your People tab becomes a living memory of who said what, organized around the people in your life. • Apple Watch + share extension. Record voice notes from your wrist. Save anything from any iPhone app with the share button. WHO IT'S FOR Built first for families. Couples managing the everyday — kids, school, the dentist, the babysitter, the grocery list that lives in three places at once. Parents who keep losing the things their kids told them. Households tired of the same conversation: "I know we wrote that down somewhere." Just as good for any group that shares a life or a project. Friend groups planning a trip across a hundred photos and links. Founders catching customer feedback fragments. Roommates juggling bills and repairs. Or just you on your own — your personal pool is yours alone. CORA Cora is your help assistant inside CRTX. Ask her how a feature works, where to find a setting, or what an option does. She knows the app inside and out — so you don't have to. SUBSCRIPTION Choose Personal for just yourself, or Family for up to 6 people. Both start with a 7-day free trial. Cancel anytime in Settings ▸ Subscription ▸ Manage Subscription inside the app. Either plan includes unlimited capture, AI question-answering, shared pools, Apple Watch, and the share extension.
