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/

Thought is a place to pour your mind out — and get it back. A stray idea. The name of a café. A photo of a book cover. The list of things to do when you get home. Type it, photograph it, record it, or paste a link. Thought saves it the moment it happens. Then ask. “Where was that café in Kyoto?” “What was I going to do when I got home?” Ask searches what you saved and answers with your own memory. Capture in a breath Text, photos, voice notes, places, and links. Paste a URL and Thought pulls the card. Record audio and it becomes text. Write #like this and it becomes a filter. Everything on one board Your notes pile into a scrapbook you can wander back through. Drag them, reopen them, search them. There’s a day-by-day list, tags, an archive — and a title on every note, so the important line is the one you see first. Ask your memory Ask answers from what you wrote, said, and saved. On your device, with Apple Intelligence, it’s free forever. Nothing invented: only what you left behind. Thought Pro Cloud AI that can see your photos, text read from pictures, and Thought on the web — the same account, the same board. On-device Thought stays free for everyone. Thought Pro renews automatically until canceled in your App Store settings. Manage or cancel in Settings → Subscriptions.
