Your first capture

Now that you have an account and the browser extension installed, it is time to capture your first piece of content. This guide walks you through the capture process step by step, explains what happens behind the scenes when AI processes your entry, and shows you how to find it in the dashboard.

Capturing a web page

The simplest capture is saving a web page you are reading. Follow these steps:

1. Navigate to any web page you want to save (an article, a blog post, a documentation page)
2. Click the Ultrathink extension icon in your toolbar, or press Ctrl+Shift+4 (Windows/Linux) or Cmd+Shift+4 (Mac)
3. The capture popup appears, showing:
   • Title: auto-extracted from the page
   • Type: auto-detected (for example, "link" for a standard web page)
   • Notes: an empty text field for your thoughts
4. Optionally, type a note about why you are saving this page or what you want to remember
5. Click Save, or simply wait three seconds for the auto-save to trigger

That is it. Your first entry is now in your knowledge base.

Tip: Adding a short note at capture time helps you remember why you saved something. Even a single sentence like "Good overview of project planning methods" makes the entry much more useful later.

Other ways to capture

Beyond basic page capture, the extension supports several other capture methods.

Screenshot capture

Save a visual snapshot of the current page:

1. Press Ctrl+Shift+5 (Windows/Linux) or Cmd+Shift+5 (Mac)
2. Alternatively, click the camera icon in the capture popup
3. The screenshot is automatically attached to your entry

Screenshot capture requires Chrome 127 or later. Some pages (banking sites, DRM-protected content) may block screenshots.

Selected text capture

Save a specific passage of text as a snippet:

1. Highlight the text you want to save on any web page
2. Press Ctrl+Shift+4 (Windows/Linux) or Cmd+Shift+4 (Mac)
3. The selected text appears in the capture popup
4. Add notes if you like, then save

This is useful when you only care about a particular paragraph, quote, or code block rather than the entire page.

AI conversation capture

When you are on a ChatGPT or Claude conversation page, the extension automatically detects this and extracts the full conversation, including individual messages and code blocks. Just click the extension icon and save as normal.

Bulk tab capture

Save all your open tabs at once:

1. Open the capture popup
2. Check the All tabs option
3. Click Save

Each tab becomes a separate entry. If your tabs are organised into tab groups, the entries are optionally grouped by the tab group colour and name.

What happens after you capture

When you save an entry, it does not just sit there as a bookmark. Ultrathink's AI processing pipeline kicks in automatically.

The processing pipeline

Here is what happens in the background after every capture:

Step	What the AI does	Typical time
1. Content extraction	Pulls the page title, description, author, published date, and favicon	Instant
2. Summarisation	Generates a summary tailored to the content type	A few seconds
3. Classification	Extracts topics, identifies people, assigns a category (Work or Personal)	A few seconds
4. Relationship detection	Finds connections to your other entries	A few seconds
5. Similarity matching	Identifies semantically similar entries you have already saved	A few seconds

You can track the progress of this pipeline on the entry's detail panel under AI Progress.

Auto-detected content types

The extension recognises over 20 content types based on URL patterns:

URL pattern	Detected type
chat.openai.com	ChatGPT conversation
claude.ai	Claude conversation
perplexity.ai	Perplexity search
notion.so	Notion page
youtube.com, vimeo.com	Video
linkedin.com/in/	Profile
SharePoint, OneDrive	MS Office documents
Any .pdf URL	PDF document
Standard web pages	Link

The type is set automatically and determines how the AI summarises the content. For example, a ChatGPT conversation gets a different kind of summary than a news article.

Viewing your entry in the dashboard

After capturing, head to the web app to see your new entry.

1. Go to tryultrathink.com and log in (or switch to the tab if you already have it open)
2. Click All Entries in the sidebar
3. Your new entry appears at the top of the grid (entries are sorted by newest first by default)

What you will see on the entry card

Each entry in the grid shows a summary card with:

• The page title
• The content type icon
• A snippet of the AI-generated summary (once processing completes)
• Any topics that have been applied
• The capture date

Opening the detail panel

Click on the entry card to open the detail panel on the right side of the screen. The detail panel shows everything about the entry:

Section	What it shows
Title	The entry title, with a link back to the original source
AI Summary	An auto-generated summary of the content
Notes	Your notes from capture (editable with rich text)
Content	The extracted content (for conversations, emails, and similar content types)
Screenshot	Any attached images
Topics	Topic labels applied to the entry
Metadata	Type, entity type, category, and dates
AI Progress	The status of each processing step
Related	Other entries the AI has found to be related
Similar	Semantically similar entries in your knowledge base

Editing your entry

You can edit any part of the entry from the detail panel:

• Click the title to rename it
• Click into the Notes area to add or change your notes
• Add or remove topics to improve organisation
• Change the entity type (Project, Task, Knowledge, or Unclassified)
• Set the category to Work or Personal
• Click the star icon to mark it as a favourite

Trying different capture types

Now that you have made your first capture, try a few different types to see how the AI handles them differently:

• An article or blog post: save it and compare the AI summary to the original
• A YouTube video page: the AI extracts video metadata and provides a summary
• A ChatGPT or Claude conversation: watch how it extracts the full conversation thread
• Selected text: highlight a key paragraph on any page and capture just that snippet

Each content type gets a tailored summary and classification, so experimenting helps you understand how Ultrathink adapts to different kinds of content.

Keyboard shortcuts reference

Action	Windows and Linux	Mac
