Capture everywhere on Ultrathink | A second brain built by an ADHD brain

Browser extension: install and connect

Mon, 01 Jan 0001 00:00:00 +0000

The browser extension is the quickest way to save what you find on the web. One shortcut saves the page you are on, the text you have selected, an area of the screen or a whole AI conversation. This page covers installing it, connecting it to your account and keeping it up to date.

What you need

An Ultrathink account with a verified email address. See Creating your account.
Chrome, Edge, Brave or another browser built on Chromium. Firefox and Safari are not supported.
A device key for this browser. See Connect an app with a device key.

Install the extension

There are two ways to get it. Both are in the web app under Settings > Downloads, in the Browser extension group.

Capturing pages, selections and screenshots

Mon, 01 Jan 0001 00:00:00 +0000

With the extension connected, saving anything from the web takes one shortcut. This page covers the save popup, selections, screenshots, saving every tab at once, and what the extension picks up from each kind of page.

If you have not set the extension up yet, start with Browser extension: install and connect.

Save the page you are on

Press Ctrl+Shift+4 (Cmd+Shift+4 on a Mac), or click the Ultrathink icon in the toolbar.
The popup opens. It shows the page title and address, a type list and a notes box.
If you want, type a note. Your note is kept separate from the page content, so you can always tell your words from the page’s.
Stop typing. After three seconds the popup saves the page and closes.

There is no Save button. The popup saves itself in three ways:

Capturing AI conversations

Mon, 01 Jan 0001 00:00:00 +0000

Good answers from an AI chat are easy to lose in a long history. The browser extension saves the whole conversation as one entry, with every message, so you can search it, link it to your work and come back to it later.

You need the extension installed and connected first. See Browser extension: install and connect.

Which chats it can save

Service	Addresses it recognises	Type it sets
ChatGPT	chatgpt.com and chat.openai.com	ChatGPT
Claude	claude.ai	Claude
Perplexity	perplexity.ai	Perplexity

The extension sets the type from the address when the popup opens. On any other AI chat site it saves the page as a normal link, with its title and address but not the conversation.

Desktop app: install and connect

Mon, 01 Jan 0001 00:00:00 +0000

The desktop app is a small window that sits on top of everything else on your screen. Type a note, drop a file, take a screenshot or record audio without switching to your browser. It also shows reminders for tasks that are due. This page covers installing it, connecting it to your account and finding your way around its window and tray menu.

For what you can capture with it, see Capturing with the desktop app.

Capturing with the desktop app

Mon, 01 Jan 0001 00:00:00 +0000

The desktop app is built for capturing in the moment, without leaving what you are doing. Everything you put in it is saved to your account and filed by the AI, the same as anything saved from the web.

If you have not installed it yet, start with Desktop app: install and connect.

Quick notes

Click in the note box. It says “Add notes…” when it is empty.
Type your note.
Stop typing. The top of the window says “Auto-saving in 3s…” and counts down. Typing again starts the count again.
The note saves and the box clears for the next one.

There is no Save button in the normal window. Press Enter to start a new line; the note saves itself three seconds after you stop.

Task reminders

Mon, 01 Jan 0001 00:00:00 +0000

The Ultrathink desktop app can remind you of tasks that are due today or overdue. Reminders arrive as normal notifications on your computer, at the times you choose, and clicking one opens the task. They are free on every plan.

Reminders are off until you turn them on.

What you need

The desktop app, installed and connected with a device key on each computer you want reminders on.
Tasks with due dates. See Due dates, waiting on and links.

Reminders come only from the desktop app. The web app and the browser extension do not show them.

On your phone

Mon, 01 Jan 0001 00:00:00 +0000

An iPhone app is coming soon. Until then, use the web app on your phone. There is nothing to install: open your phone’s browser, go to tryultrathink.com/app and sign in.

What you see depends on your phone.

Device	What the web app shows
iPhone	A quick capture screen, made for saving things fast with one thumb
Other phones	The full Ultrathink app, with the sidebar behind a menu button in the top bar
iPad and other tablets	The full Ultrathink app

Everything you save on your phone goes to the same account as your computer, and the AI files it in the same way.
