Basic types

Weblinks

In Capacities, weblinks are not just URLs in your notes. They are their own entities. Open the Weblinks object type in the left sidebar to see them all.

Every saved weblink is a weblink object, which means it can be tagged, enriched with notes, and reused across your space with the usual @ or [[]] shortcuts.

Weblink properties

Every weblink object in Capacities comes with a set of properties that help you describe, organize, and query your saved links:

  • Title – The name of the weblink object, often filled from the page metadata.
  • Tags – Labels you can assign to group related weblinks.
  • Description – A short text summary, often filled automatically from the page.
  • Blocks – Where you write your notes on the weblink.
  • URL – The saved link you can open or copy to clipboard.
  • Category – A predefined classification used for filtering and queries.
  • Topic – A broader theme used for grouping and queries.
  • Keywords – Key terms extracted from the page when you run weblink analysis.

When you first save a link, Capacities loads the title, description, and preview image if the page provides them.

Capacities Believer users with AI enabled can use weblink analysis to fill these properties automatically.

Users on other plans can still use the properties manually.

Pro users can use these properties to build queries.

Adding a weblink

Paste a link into Capacities, either in a block in any object or in the command bar (Cmd/Ctrl + P/K). Capacities asks whether you want a simple inline URL or a full weblink object with tags and notes.

If you only need a URL for quick reference, keep the simple link. This is called an inline link:

If you want to reference the link in other pages or add notes directly to it, choose the weblink option.

On Mac, you can also use Hookmark to create weblinks without opening Capacities, or save links from the browser with the web extension or Raycast.

Reading and annotating on desktop

Weblink analysis and annotations are currently available for Capacities Believer users on desktop.

On desktop, open a saved weblink to read the page inside Capacities. The weblink opens with three tabs at the top:

  • Browser – Preview the live webpage in Capacities' built-in browser. This tab needs an internet connection.
  • Reader – Read a clean, distraction-free version of the article. Most saved weblinks are supported.
  • Summary – Read the generated overview after you run analysis.

Switch between the tabs whenever you like.

The Reader tab is supported for most saved weblinks. You can use it and annotate without running analysis, but we recommend running analysis for a more stable cross-device experience.

Most pages work well in the Reader tab. For technical reasons, the full article may not always be available.

In the Reader tab, you can use find in page (Cmd + F / Ctrl + F) to search text in the saved article.

Annotations linked to note blocks show their note icon in the Reader tab. Hover an annotation to see a preview of the linked note.

Once analysis has finished, the Reader tab works without an internet connection because the article content is saved on the weblink object. The Browser tab still needs a connection to load the live page.

Annotating weblinks

Select any passage in the Browser or Reader tab to highlight it in different colors and add notes. Annotations live on the weblink object and flow into your notes the same way highlights from the Readwise integration do.

Highlights appear with a colored bar on the left. Notes on a highlight are shown below in smaller text. Choose between Default and Minimal styles in Settings > Editor > Highlight Style.

Highlights are shown as annotations rather than as part of the original text. Child highlights are toned down so they read as your notes, separate from the source. Click a highlight to jump to the relevant place in the page content.

You can delete a highlight in the Browser tab, Reader tab, or from the note blocks where it appears. If you delete the note block, the annotation is removed too.

The Browser, Reader, and Summary tabs, annotation tools, and Analyze button are only available on desktop.

Weblink analysis

Weblink analysis is part of Capacities' media analysis feature. It helps Capacities understand the content of a saved webpage so you can search it, filter it, and use it as context in AI chat.

Weblink analysis is available for Capacities Believer users with AI features enabled. It only runs in spaces where AI is turned on.

On desktop, open any weblink and click the Analyze button in the weblink toolbar or object menu. Capacities processes the page and fills in the following:

  • Summary – A short overview of the article, shown in the Summary tab on the weblink.
  • Keywords – Key terms from the page, written to the weblink's Keywords property.
  • Category – One of a selection of predefined categories, written to the weblink's Category property.
  • Topic – A broader theme for the page, written to the weblink's Topic property.
  • Saved article content – The page content saved to the weblink for the Reader tab, full-text search, and AI chat context.

If you want to run analysis again, for example after a page has been updated, use Retry in the weblink object menu.

Analysis uses your AI budget. Longer pages use more budget. The process is optimized, so the impact on your budget should stay low in most cases.

There is a technical length limit, but most articles stay well below it.

Generated summaries and keywords are not editable right now. You also cannot clear analysis results manually yet.

All extracted data is written to the weblink's properties automatically, making your weblinks queryable and filterable across your space.

Analysis results are integrated directly into the weblink UI. Open the Summary tab to read the overview, switch to the Reader tab to read the saved article, or add the weblink as context in AI chat to ask questions about the page.

Some websites block access or require a login. Others present content in ways Capacities cannot read reliably. In most cases, articles and public webpages should work well. If analysis does not work for a page, you can still keep the weblink object and add your own notes below it.

Search and AI chat

Summaries, keywords, and saved page content are included in search. When a search result comes from a saved weblink, Capacities opens the Reader tab and scrolls to the matching paragraph.

The same extracted information is available as context for the AI assistant. Add the weblink as context and ask questions about the article.

Across devices

Analysis only runs on desktop. Once it has finished, the extracted data is saved to the weblink object and synced across your devices. You can then see the summary, keywords, category, topic, and annotations on the weblink wherever you use Capacities.

If you re-run analysis and the page content has not changed since the first run, highlights are usually reanchored. This is not guaranteed.

Language handling

For weblink analysis output:

  • saved article content keeps the original language of the page
  • generated fields (for example summary, keywords, category, and topic) follow your AI output language settings first, then your app language as fallback

When you run a weblink analysis, the page content is sent to the AI model provider for processing. No page content is sent unless you click the Analyze button. For full details on how your data is handled, see AI and Privacy.

Weblink analysis requires Capacities Believer with AI features enabled. Analysis only runs when you trigger it on desktop (for example by clicking Analyze).

If your AI budget is exhausted, the action shows an AI budget used state and opens AI settings.

Weblink views

When you embed a weblink in your notes, you can choose how it looks on the page. These are the same view options offered for most object types.

➡️ In Line Weblink

➡️ Link Block Weblink

➡️ Small Card Weblink

➡️ Wide Card Weblink

Supported Weblink Embeds

You can change the view of the weblink to an embedded view, which will show the content of the webpage directly in Capacities.

Capacities tries to extract the embed link of the webpage you are trying to embed.

➡️ For privacy reasons, each new website you embed content from will need your explicit permission first before displaying anything.

➡️ For some websites, you might need to be logged in to see the content. Capacities will not be able to embed content from these websites due to technical restrictions.

We often add more websites to this list. You can request embed support on our feedback board. Please send one website request per ticket. If you have multiple requests, send multiple tickets.

Some websites may not allow embeds, in that case you will see a message saying that the website does not allow embedding. Other websites require a specific embed link to be used. You can find the embed link by looking for share options or by reading the website's documentation.

If you want to add an embed link to your Capacities object you need to open it in the table view and paste it into the embed link field.

Taking notes on web articles

A common use for weblinks is articles you have read. Create a weblink, run analysis on desktop if you want richer metadata, and add your own notes in the blocks below. Tag the weblink or filter by Category and Topic in queries to fit it into your existing workflows.

As with all other notes, you can link to other objects and edit styles.

Using Hookmark

Capacities and Hookmark have an integration which can help super-power your workflows on your Mac. We have an in-depth article about it here.

To create weblinks in Capacities from the web without copy and paste, use the Hook to New function.

Using the Web Extension

You can save weblinks directly from the browser with the Capacities Web Extension. See more here.

Using the Raycast Extension

When on a webpage whose link you want to save, open Raycast and run the Save Weblink command.

See more here.

FAQ

  • How do Category and Topic work with collections?
    If you've been using collections to categorize content, you can now let the built-in Category and Topic properties do that work automatically with queries. For example, instead of maintaining a collection, you can create a query on Weblinks filtered by the Category property.
    Collections are still useful when you want to manually curate items (for example, "my favorite articles"). But for rules-based groups, queries based on Category/Topic can replace those collections and keep your setup cleaner. For more on this, see Can I customize the options for Category, Colors, and Topics?.
  • Do I need to use AI weblink analysis to use the Category and Topic properties?
    No. You can fill both properties manually, or use weblink analysis to fill them automatically along with Keywords and the summary.
  • How do weblink annotations relate to Readwise highlights?
    Annotations live on the weblink object and flow into your notes the same way highlights from the Readwise integration do.
  • Can I use weblinks for tweets?
    This isn't possible, tweets are automatically recognised as such.
