Which Articulate software

Is there a way to take an existing PowerPoint presentation and use either Storyline or Rise to insert narration, polling with feedback data? 

Which of these tools is the best to use? Is there another tool from the Storyline 360 that lends itself more useful for adding narration and polling with feedback? If so please advise. 

Are there training documentation that shows how (for any of these applications)?

thank you in advance for any info provided!
