01
Feels like a real conversation
Short replies, no lectures. Interrupt any time. It asks one question at a time and keeps track of everything you said.

Keeps working after you hang up
Research with sources, a plan with next steps, and tasks with time estimates, ready when you come back.
What you get

FAQ
Questions before you download
What oThought is, what it costs, and what happens to your data.
What is oThought?
oThought is an app you call to talk through an idea. You can also leave a voicemail. It saves the idea, asks questions to fill in the details, researches it, connects it to your other ideas, and gives you a plan you can start.
How is it different from Voicenotes, AudioPen, Otter, or Apple Voice Memos?
Those apps record what you said and clean it up. oThought talks back: it asks you questions during the call. After you hang up, it researches the idea with sources, connects it to your other ideas on a Mastermind Map, and makes a plan, tasks, and notes for your next call.
What does oThought cost?
The free trial gives 10 total voice minutes and 2 saved ideas with no card. Pro is $2.99 per week or $29.99 per quarter. Founder is $9.99 per week or $99.99 per quarter. Extra voice minutes are available as $6.99 and $19.99 top-ups. There is no unlimited voice plan.
Which languages does oThought support?
The app ships in 19 languages: English, Arabic, Bengali, Chinese, Dutch, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Thai, Turkish, Vietnamese.
Is my voice data deleted when I delete an idea or my account?
Yes. Deleting an idea removes its calls, transcripts, recordings, plans, and research from the app and its cloud-synced record. Deleting your account removes the account record and all of that content, except records we must retain for legal, tax, billing, fraud-prevention, security, or dispute-resolution reasons. Deleting an account does not cancel an Apple or Google subscription.
Does oThought work on iPhone and Android?
Yes. oThought runs on iOS 16.4 or later, including iPad, and on Android 8.0 or later. It installs from the App Store and Google Play.
Have an idea on a walk?
Call oThought before it slips away. Hang up with the idea saved, researched, and turned into a first step.
