- How are messages calculated?
- Each reply sent by Kastro with length of 1,500 tokens is counted as one message. However, messages sent by your operator to customers aren't counted.

- Once your message credits run out, any messages from your customers will be automatically forwarded to an operator, and Kastro won't respond to them.
- Do you use ChatGPT (aka gpt-3.5-turbo) or GPT-4?
- We currently use gpt-3.5-turbo as default, for our chatbots but GPT-4 is available.
- Can I use GPT-4?
- Yes, you can use GPT-4, but it will cost four times the normal messages.
- Does it work on websites in languages other than English?
- Yes, Kastro works on websites in languages other than English.
- My company needs a custom integration or custom feature that is not yet supported by Kastro. What should I do?
