May I suggest that you let us customize a list of pre-typed questions that will show up under the “Summarize this page/video” button? Perhaps as an alternative to the smart questions or as an addition to them.
My usecase was that I had to type the same question for 100+ tabs: “Give me a bookmark title for this page that will be easily searchable and that contains any keywords from this page.” It would be awesome if I could have this and potentially other questions just one click away.
Other potential useful questions would be “Give any contact details that you see on the page”, “Please ELI5” etc. But why not let the users customize them
