Your first capture

The quickest way to learn Ultrathink is to save something and watch what happens to it. You can do that straight from the web app, with nothing to install, or from the browser extension.

Capture from the web app

1. Open Ultrathink at tryultrathink.com/app.
2. Click New entry at the top of All items, or press N on any page. Quick capture opens.
3. Type a note, or paste a link into Paste a link (optional).
4. Stop typing. It saves itself after 3 seconds, or click Save to save now.

You can also drop a file, a link or some text anywhere on the window, or press and hold New entry to record a voice note. Capture in the web app has the details.

Capture from the browser extension

The extension saves the page you are reading, a piece of text you have selected, or a screenshot of part of the page. Install it and connect it first: see Browser extension: install and connect.

Save a page

1. Open any web page.
2. Click the Ultrathink icon in the toolbar, or press Ctrl+Shift+4 (Cmd+Shift+4 on a Mac).
3. The popup shows the page address, a Type list and a notes box. The type is picked for you from the address.
4. Add a note if you like.
5. Leave it. The popup says Auto-saving in 3 seconds… and saves. Typing or changing the type starts the countdown again. Clicking away or closing the popup also saves.

There is no Save button: the popup always saves when it closes.

Save some text from a page

1. Select the text on the page.
2. Press Ctrl+Shift+4 (Cmd+Shift+4 on a Mac).
3. The popup shows the text you selected. It saves as a snippet, with the page address kept.

Save a screenshot

1. Press Ctrl+Shift+5 (Cmd+Shift+5 on a Mac).
2. Drag over the part of the page you want. Press Esc to cancel.
3. The popup opens with your screenshot, and saves in the same way.

Save every open tab

Tick All tabs in the popup. Each tab in the window is saved as its own entry, and tab group names and colours are kept.

If a save fails

The extension keeps saves that did not go through. The popup shows them with Retry and Dismiss.

What the AI does next

Every new entry goes through five AI steps in the background:

On the Free plan these steps use your own OpenAI key, added in Settings > Integrations. On Pro they are included.

While the AI works, the new entry’s row in a list or table shows an orange band at the start of its title, saying what it is doing, such as Summarising. The entry does not say Unclassified until the AI has finished deciding what it is. How the AI files your entries explains each step.

Find what you saved

1. Click All items in the sidebar.
2. Your new entry is at the top. The list is ordered newest first by default.
3. Click it. The detail panel opens on the right, with the title, your notes, the AI summary, the topics and people, and any related entries.

You can change the title, edit your notes, add topics, make it a task, or star it from there. See The detail panel.

What gets detected from the address

The extension sets the type from the page address. A few examples:

You can change the type in the popup before it saves. For conversations, see Capturing AI conversations.
