About us
We build websites for UK businesses. Chati is what they kept asking for.
Chati is made by PS Website Design, a UK web design and hosting company. We built it for our own clients first, and now it’s available to every business.

Our story
From one CRM feature to its own product
For years we’ve designed, built and hosted websites for small and medium businesses across the UK. The same problem came up again and again: enquiries arriving at 9pm, the same ten questions answered by hand every day, and no time to get to the ones that mattered.
So we built an AI assistant into Ripple, our own CRM. It answered from each business’s website, showed where its answers came from, and handed the chat to a person when it wasn’t sure. Our clients liked it so much they wanted it on its own.
That’s Chati: the same assistant, now standalone, priced in pounds and supported by the people who built it.
What we believe
“Let me check” beats a wrong answer
An assistant that guesses costs you customers. Chati asks, or brings in a person.
People stay in charge
AI should take the repetitive work, not replace the team your customers trust.
Plain English, plain pricing
Prices in pounds, no credits to decode and no surprise bills.
Real help, from real people
