Custom URL Field for Linking External Tools to Bookmarks

Describe the feature you'd like

Feature Request: Custom URL / External Link Field on Bookmarks

I would like to have a dedicated, clickable URL field on each bookmark — either as a new built-in field type or as a custom property — that can be used to store a link to an external tool or platform.

Use Case

I have built a custom platform that generates summaries of YouTube videos. My workflow is:

1. A video is added to Karakeep and sent to my platform via webhook.
2. The platform processes the video and writes the summary back into the Karakeep note field.
3. I then manually paste the link to the processed entry in my platform into the note field so I can navigate back to it.

This last step is what I'd like to improve. Instead of embedding the link inside the notes, I'd love a dedicated URL field that:

• Stores a link to the corresponding entry in my external tool
• Is rendered as a clickable hyperlink in the Karakeep UI
• Is excluded from search results (it is not part of the bookmark's content)
• Has no semantic relationship to the bookmarked content itself — it is purely a reference/pointer to another tool

Proposed Solution

A custom property field of type URL (similar to how Notion or other tools handle custom properties) would cover this perfectly. Alternatively, a dedicated "Related Link" or "External Reference" field on bookmarks would also work.

The key requirements are:

• Accepts a URL as input
• Displayed as a clickable link in the UI
• Not indexed for search
• Accessible via the API so it can be written by webhooks or integrations

Describe the benefits this would bring to existing Karakeep users

Users who integrate Karakeep into broader automation workflows — for example, connecting it to AI processing pipelines, summarization tools, or other archiving systems — currently have no clean way to store a back-reference to those external tools. The only available workaround is to embed the link in the note field, which pollutes the note content and causes the URL to appear in search results.

A dedicated URL field for external references would:

• Keep bookmark notes clean and focused on content
• Allow users to maintain cross-tool references without workarounds
• Enable automation tools (via API/webhook) to write back a reference URL after processing a bookmark
• Improve the overall experience for power users building custom integrations on top of Karakeep

Can the goal of this request already be achieved via other means?

Partially — yes. The link can currently be pasted into the note field. However, this approach has several drawbacks: the URL becomes part of the searchable text content, the note field is meant for human-readable summaries rather than metadata, and there is no way to distinguish the external reference link from the actual note content programmatically or visually. A proper URL field would solve all of these issues cleanly.
