What each plan includes
Setup is paid once. The monthly recurs, and the overage applies only past the allowance.

Answers, the allowance, and renewal
An answer is one reply from the agent to one message, on your website, by email, or in the search box. A visitor who asks whether you take Tricare and then asks about your second location has used two, and a customer email that gets a draft has used one. Every plan includes 1,000 a month, and that covers a typical month because the same twenty questions come from far fewer than a thousand people.
Past the allowance, answers are $50 per thousand, agreed in advance on the call. Nobody is invoiced for answers they did not agree to pay for.
Setup is paid once. The monthly renews month to month with no annual term, and cancelling stops the agent at the end of the month you paid for. Your pages and your transcripts are yours, and the data page says what is kept and who can see it.
Work priced separately
The agents above answer and hand off. Four things sit outside the monthly.
- Booking, ordering, and payment
- Anything that writes into another system is AI Integration at Gray Sand Technology, and it is the usual second step once the agent has been answering for a few months.
- Automations that run on their own
- A multi-step job that runs without a person watching is AI Workflows, priced as its own engagement.
- A staff-facing assistant
- An assistant over a CRM, an ERP, or private records is AI Integration at mid-market scope.
- The phone
- Shelly does not answer it. It works the website, the inbox, and the search box.
Questions before the call
Do I need a new website?
No. The Site Agent is one script tag, and it goes on WordPress, Squarespace, Wix, or Shopify, or through Google Tag Manager, on a site Gray Sand did not build.
What happens to my content?
Shelly reads your public pages and the text you add, keeps them in an organization that holds your content and nobody else's, and answers only from them. None of it is used to train any model.
Can it answer in Spanish?
Yes. The agent answers in the language the person wrote in, so a visitor who writes "¿Aceptan Medi-Cal?" gets the answer in Spanish, from the same pages as the English one.
What does it not answer?
Anything your pages do not cover. It says it does not have that information and offers to have someone from your team follow up, and it never invents a price, a time, or a policy.
Can I turn it off?
Yes, at any time. A paused bot stops loading on your site, and auto-send on the email agent is a switch you can turn off whenever you like, after which every reply waits for approval again.
How long does setup take?
The first read of your site runs in minutes, and the rest of setup is the call, the agent's instructions, and the preview on your own homepage before anyone else sees it. The launch date is yours.
