For that moment when you find something on your iPhone but want to deal with it on your Mac. Just tap "Relay" in the share sheet. Seconds later, it appears in the Inbox on your Mac. Not ready for it now? Send it to tonight or the weekend, and it resurfaces when the time comes. Weeks later, even if you've forgotten the title, a vague search brings it right back. ◆ How people use it - Send a GitHub repo from your iPhone to your desk - Send a restaurant from your Mac to your pocket - Capture a passing thought by voice, for your future self at the desk - Save an article you can't read now, for tonight - Recall something you saw months ago from a half-remembered phrase ◆ One verb to remember No folders. No tags. No filing. Tap Relay and you're done — the app organizes invisibly, in the background. ◆ Search that forgives forgetting Hybrid full-text and semantic search. Automatic tags bridge Japanese and English, and results show you exactly why they matched. Note: advanced bilingual auto-tagging requires an Apple Intelligence-capable device (iPhone 15 Pro or later, M1 or later Mac/iPad). Other devices get basic tags; search and text recognition work on every device. ◆ Done is not Forget Items you finish leave your Inbox but stay in Memory, searchable forever. Only Forget deletes. Inbox Zero without anxiety. ◆ On the Mac, the app disappears It lives in your menu bar. A global shortcut (customizable) opens a Spotlight-like panel over any app — your memory, one keystroke away. ◆ Anything goes in X posts arrive with their full text. Screenshots get OCR'd so you can search what was written in them. Voice notes are transcribed automatically. ◆ Privacy - Your data syncs only through your own iCloud (no account needed) - Tagging and search indexing run entirely on-device - No ads, no tracking ◆ Pricing Your first 30 items are free. After that, a single ¥1,500 one-time purchase unlocks unlimited use forever, across iPhone, iPad, and Mac. No subscription.
