Thought

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.
