It would be nice if we could connect the Assistant to something like Google Drive, OneDrive, Dropbox, or preferably for me personally, Nextcloud, so that generated (or uploaded) files can remain in the chats without expiring after 10 minutes.
This would limit the need for a "Kagi Drive" that others have suggested, in my opinion. Which is a pro to me, I like supporting more focussed products/companies without using a big "everything app" since that's how you get a Google or Microsoft 😅
How it'd work is fairly self-explanatory; in the user settings, connect using oath to the chosen cloud storage solution, and in there create a kagi folder in which you can create subfolders for assistant-images and user-uploads.
