O'Reilly is one of these companies everyone in the business has heard of. Before 1984, O'Reilly was a technical writing consulting firm. It is around that time that they started to publish books about programming, computers, and technology.
Today, O'Reilly is a trusted source of information on business and technical topics. Their online library hosts an incredible amount of books and white-papers.
Fair warning: a big part of their content is quite advanced.
What will you learn with O'Reilly's chatbot newsletter? You will receive weekly news about artificial intelligence, machine learning, and the latest insights from industry leaders.
Fair warning: their site is... well... odd. If you can see past it, you will find value. But yeah, I know, tough one.
So, this is a bit of a weird one. Like O'Reilly, KDnuggets' newsletter isn't as chatbots per se. Having said that, it is a fantastic source of information for anything that relates to AI, ML, and data science in general.
These three topics put together essentially make chatbots. Some of the content is advanced but lots of it is very readable for any knowledge level.
