Capture everywhere
Save pages, conversations, notes, files, screenshots and voice notes from your browser, your desktop and your phone.
Ultrathink is built around capture first, sort later. These pages cover the browser extension, the desktop app and its task reminders, and using Ultrathink on your phone. Every entry you save goes to the same place and the AI tidies it afterwards.
Browser extension: install and connect
Install the Ultrathink extension in Chrome, Edge or Brave and connect it to your account with a device key.
Capturing pages, selections and screenshots
Save a web page, a piece of selected text, an area of the screen or every open tab with the browser extension.
Capturing AI conversations
Save whole ChatGPT, Claude and Perplexity conversations into Ultrathink with the browser extension, so you can find the answers again.
Desktop app: install and connect
Install the Ultrathink desktop app on Windows or Mac, connect it with a device key, and learn its window, tray menu and updates.
Capturing with the desktop app
Type notes, drop files, take screenshots and record audio with the Ultrathink desktop app, and what happens when a save does not go through.
Task reminders
Get reminders from the Ultrathink desktop app for tasks that are due today or overdue, at the times you choose.
On your phone
An iPhone app is coming soon. Until then, use the Ultrathink web app on your phone to capture notes, photos, drawings and voice notes.
