Chattysun

A simple script tag is all Chattysun needs to put a custom AI chatbot on your website. Chattysun is an AI customer service tool that lets online businesses build their own chatbots to answer visitors and handle sales questions through a chat interface.

There is a free plan at $0 a month.

It gives you a custom bot with all features, though request limits apply.

The Business plan costs $49.99 a month, covers up to 5k messages per month and uses the best available AI.

Corporate is $199.99 a month, raises the cap to 20k messages and adds tailored instructions, custom behavior and rules, and installation help with the highest performing assistant.

Larger companies can ask about the Advanced Enterprise tier, which is priced on request.

It lists a certified vendor process, high throughput, custom integration, compliance solutions, and a choice of hosted or on-premise deployment.

The free tier makes it easy to test a bot on a live site before you decide whether message volume justifies paying for a higher plan.
