It would be great to have the functionality for the iPadOS safari extension, to have a button in one of the corners of the search engine that allows you to access a widget to use Universal Summarizer directly on the website or, from the extensions bar directly from the Kagi extension, without the need to leave the page. It could work on web pages, videos, pdf's, etc. This would make it much faster to summarize content on the web.
I see this functionality implemented in the Kagi extension for iPadOS safari and all other versions of the extension. I would even consider implementing it in Orion. I think that implementing this feature with Kagi would be very good to summarize web pages, pdf's, videos, in a simple and intuitive way without leaving the web page.
For references, the Briefy application already has this functionality available in its safari extension.
