MemX is your AI memory — a second brain that reads everything you save and answers in plain words, so you never dig through files again. We all have critical info scattered across photos, PDFs, WhatsApp messages, and voice notes. Searching it is a nightmare. MemX reads it all — even the text inside your photos, documents, and audio — then connects the dots so you can ask a question and find what matters in seconds. WHAT YOU CAN DO Search inside any document PDFs, contracts, leases, research papers, specs, statements, certificates. Drop them in once, then search inside them anytime — without opening the file, remembering the filename, or tagging anything. Record and transcribe any conversation Meetings, interviews, calls, lectures, doctor visits. MemX records, transcribes, and turns hours of audio into structured notes with action items. 100+ languages, mixed-language recordings in one session. Set reminders and to-dos by voice Just say it in plain words: "Remind me every Monday and Thursday to follow up with the client for the next six weeks." MemX sets the recurring reminders, ends them on time, and won't let them go until you mark them done. It even pulls to-dos out of your documents automatically. Bring in WhatsApp Forward documents, photos, voice notes, and full chat histories to MemX once — then search them forever. Pull up the contract a client sent or the doctor a friend recommended months ago. Capture from your camera Point your camera at a prescription, business card, whiteboard, contract clause, error screen, or napkin sketch. MemX reads what's inside and makes it searchable forever. THEN JUST ASK "What's the indemnification clause in the Acme contract?" "What were the action items from last Tuesday's review?" "When does my insurance policy expire?" No folders. No tags. No filenames. Ask in plain words — in any language — and your AI memory finds the answer inside the document, recording, photo, or chat where it lives. BUILT FOR PROFESSIONAL USE Search across every contract, spec, recording, and client document you've saved. Cross-reference findings across hundreds of research papers in one query. Pull up boarding passes, prescriptions, lab reports, bills, and warranties without opening a single file — your whole life, searchable. PRIVATE BY ARCHITECTURE Per-user encryption with keys only you control. Even the MemX team can't read your data — not as a policy, but as a property of the system itself. Your content is never used to train AI models. Delete everything, anytime. Stop remembering. Start asking. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Eidra is a quiet memory for the people in your life. Tap once. Speak. Or type a few words. The AI listens, extracts the names, places, interests, and follow-ups, and holds them for you. Months later, when you bump into someone and your mind goes blank, you ask Eidra. The answer is already there. WHO IT'S FOR The friend you saw at a dinner party last spring (whose new partner's name you keep almost remembering). The neighbor you've waved at for two years and never quite caught the name of. The mentor you met at a conference whose advice you can never relocate when you need it. Your kid's teacher, your cousin's husband, the barista who knows your order, the new colleague who mentioned a hobby you wanted to ask about. The dating app match whose stories you want to hold onto. The mom of your daughter's classmate. Anyone you've ever wanted to remember a little better. FOR WORK, TOO Sales reps building rapport with prospects across long deal cycles. Founders tracking the people they meet at every dinner, conference, and intro coffee. Recruiters keeping context on candidates and clients. Investors holding onto the threads of every founder pitch. Anyone whose job depends on remembering people well. Eidra is a personal CRM that does not feel like a CRM. The same fast capture, the same effortless recall, just as useful for the prospect you met last quarter as the friend you saw last weekend. WHAT MAKES IT FEEL DIFFERENT Most apps make you do the work of organizing. Eidra does it the moment you speak. You say, "had drinks with Leslie, she just got back from Lisbon and is starting sourdough lessons." Eidra extracts Leslie, the trip, the new interest, and the date. It writes a one-line entry into her timeline. It updates her structured profile so the next time you ask, "what's Leslie been up to," it remembers all of it. Her card even grows with her: as you capture more, Eidra reconciles the details over time, remembers the family and pets around her, and links her to the people she's connected to. It is not a note-taking app. It is not a journal. It is a memory aid that makes the small details feel effortless to keep. WHAT YOU CAN ASK Once you've captured something, you can ask Eidra anything about anyone: • When did I last see Marcus? • What was the name of Sarah's daughter? • Who did I meet last month interested in startups? • What was that book Olivia mentioned? Eidra answers in your own words, the moment you need it. ALSO INSIDE • Important dates & reminders: a calendar of every birthday, anniversary, and follow-up, with an optional heads-up two days before so you never miss one • Connections: link people together and remember how they relate • Family & pets: Eidra quietly remembers the people (and pets) around the people you know • Briefings: a 30-second AI recap before you see someone again • Custom prompts: ask anything specific ("what should I bring up with Eli?") • Hidden contacts: lock private notes behind Face ID • Voice or text capture, your choice every time SUBSCRIPTION TIERS Eidra is free to start, with limits.
