Frequently asked questions
Will the bot invent answers?
Guardrails require answers from the loaded documents; out-of-scope questions go to a person. This is the key difference from embedding a basic chatbot.
What are the monthly AI costs?
It depends on chat volume. A medium-sized website is usually below 100,000–200,000 VND/month, with free-model options for low usage.
What is the refund policy?
Within 7 days of purchase, if the workflow does not work as described and our support team cannot fix it, you receive a 100% refund by bank transfer. See our refund policy.
