I have imported several pdf, rtf, and plain text files. When I highlight text (I have tried all 3 file types) and then select summarize from the edit menu, nothing changes. I only hear a beep. I am using DT Pro Office 2.0.
As I recall, either the User Guide or version notes commented that the Summarize feature is not yet active in public beta 1.
And still not working for me in beta 7!
Which is disappointing.
