Throughline is a voice-first external memory for a scattered mind. Your best thoughts show up at the worst times: in the shower, mid-meeting, walking to the car. Throughline gives you one place to put them down. Just talk, and it sorts what you said into threads (tasks, notes, appointments, lists, intentions) and hands the right one back when it matters. It's not a to-do list. It's somewhere to set things down, so your head doesn't have to hold them. HOW IT WORKS - Talk, don't type. Unwind everything at once and Throughline splits it into separate threads. - Organize by voice. Say "move the slideshow to Work" or "make a project called Wedding" and it happens. - Get one thing back. If you want it, one thread worth your attention each morning, never the whole pile. - Close the loop three ways. Finish it, bank it for later, or let it go on purpose. All three count. No overdue counter, no streaks. NEW IN 1.6 - Ask your memory: "what did I say about the lease?" It looks through everything you've unwound, finished things included, right on your phone. - Unwind from anywhere: the share sheet, Siri, or the Action Button. - Move an appointment in your calendar and Throughline moves it too. - You → Your data: see exactly what the AI saw, read everything Throughline keeps in plain words, or delete all of it. WHAT IT CATCHES - Tasks, the things you actually have to do - Notes, the thoughts you want to keep but not act on - Appointments, added to the calendar you already use - Lists you tick off later ("start a grocery list: eggs, coffee, the good bread") - Intentions, the standing "exercise more" kind of aim, three at a time - Workouts, said the way you'd tell a friend, saved to the Health tab PRIVACY, HONESTLY Voice is transcribed on your iPhone; the audio isn't uploaded. To organize what you say, Throughline uses a cloud AI (Anthropic's Claude) through our server, and your phone strips names and identifying details before anything reaches the AI. It's best-effort, not a guarantee, and you can check it yourself in What the AI saw. We keep a de-identified copy to improve Throughline, never given to AI companies to train their models, and you can switch that off anytime. You can also choose to organize on your device instead. No ads. No tracking. PRICING New accounts get two free weeks with everything. After that, there's a one-time founder price, $19.99 in the US (the App Store shows yours), sold until March 2027. It covers three years and keeps the cloud organizing, resurfacing, Rewind, Unstick and the digest emails going. Without it, capture, your own threads, reminders you've already set, export, deleting your account and Health all keep working, and new captures are sorted on your phone instead, more simply. If you had an account before version 1.6.0, nothing changes: Throughline stays free for you. You can also choose Patron, $39.99 a year, which is what Throughline becomes after the founder sale. Patron renews automatically unless canceled at least 24 hours before the end of the period. Payment is charged to your Apple Account; manage or cancel anytime in your App Store account settings. Cloud organizing has a fair-use limit of 300 captures a month, the same for everyone, payers included. Requires iPhone on iOS 26. Sign in with Apple.
