Does any know where I can find online a pdf of דרשות הר"ן that's in hebrew text and not in Rashi script/ text?
Take a look here for the text and a concise and clear commentary with PDFs too. (They don't seem to have all the דרשות though.)
Someone started uploading some of them to Sefaria which you can see here. (Full disclosure: I work for Sefaria). However I'm not actually sure how complete it is. If you let me know where the gaps are, I can (bli neder) assign someone to finish it.
Sefaria has the complete text in both Hebrew and English.
