    Great, has multiple assistants, and has good integration with Google Chrome. A great app for non-English speaking people around the world.

    I've never written a review for a chrome extension before. But this extension is that good. The chat feature is a given. However, what blew my mind about this app is the OCR tool that extracts words from images. Made my life so much easier! Just want to say a very big thank you to the Sider team.
