Someone posted on Reddit…
We recently added an AI chatbot to our website and it’s been incredible for engaging visitors and converting them into leads…
We took all our publicly available company info – white papers, webinar content, email marketing text, lead magnets, website copy, etc. – and fed it into the AI to create a custom chatbot…
Then we added a chat widget in the corner that says something like “Hey, there! I know everything about the company. Feel free to ask me anything!” …
The results have been amazing. We’re getting way more leads through the chatbot than we ever did with static forms.
How about doing this for companies as a service? 
Set up and prime the chatbot, install it on their website, monitor the results, deliver regular reports and insights.
Someone in the comments recommends Tawk.to for creating chatbots, looks like they have a free plan
