What sales tools do you use to boost conversions?

I use the Pitch Avatar functionality of ROI4Presenter. It creates scripts for a presentation from prompts and can generate a person that is conducting it. So, basically, you create a presentation that sells itself :)

I've recently heard about Proof. It has some very cool features. For example, you can adapt your site’s text, images, and CTAs for each visitor without writing a single line of code.

Recently we started using Bonjoro to reach out to everyone who starts a free trial on our tool and I think it's great. What are some other tools you recommend?
