Adding AI to a website usually means one of a few concrete changes: search that understands a plain-language question, an assistant that walks a customer through a routine task such as filing a claim, or testing and personalization that runs faster than a team could manage by hand. Each of the 10 agencies below names at least one AI project for a client on its own website. Some of those projects sit inside a live site and some sit behind it, in campaigns or operations, and the entries say which.
The order rests on five things: how close each agency's named AI work sits to a working website, the sites it has launched, results it publishes for named clients, its technical range across search, CRM, CMS and integration work, and the size of its team.
How to choose
If visitors can't find the right page
AI-powered search is the closest fit. Isadora Agency's platform for a multi-campus technical college includes search that reads natural-language questions and returns matching programs, services and next steps.
If customers call to finish routine tasks
VML built a chatbot into a UK warranty provider's online claims journey so customers can register a claim without logging in. TCS Interactive's parent company added GenAI agent assist and chatbot work to a TV and streaming company's customer service.
If pages need testing and personalizing faster
Bounteous switched on AI-driven testing in Adobe Target for a retail pharmacy chain, with governance and a shared scorecard so business units agreed on what success meant.
If the AI work is mostly content
Monks used generative AI workflows to concept and produce personalized ad creative for a sleep wellness company, and DEPT built AI agents that check incoming ad creative against brand guidelines for a retail media business.
Most AI features on this list run on a model the agency didn't build
Most of the AI examples on this list are integrations. TSTC's natural-language search runs through Element 451, the college's CRM. VML built Domestic & General's claims assistant on Google's Dialogflow, Monks produced Hatch's ad creative with Google Gemini inside its Monks.Flow workflow, and Perficient's invoice-matching tool for ArchKey Solutions uses Azure OpenAI.
The agency's contribution is choosing the service, connecting it to the client's data and designing what the visitor sees. So the evidence that counts is integration experience and content structure.
AI work splits between the website and the back office
Some of the named AI projects change what a visitor sees: TSTC's AI-powered search, implemented through Element 451 on the platform Isadora built, Domestic & General's claims chatbot (VML) and the AI testing Bounteous set up for a retail pharmacy chain. Others run behind the scenes, such as DEPT's asset-checking agents for Nectar360, Perficient's invoice matching for ArchKey and the contact-center tools TCS built for Foxtel.
A buyer who wants AI on the site itself gets more from the first group's case studies. The second group shows engineering range, which matters when the AI feature has to pull from internal systems.
What an AI website project costs
Isadora's inquiry form carries the only published pricing on this page. Website and product design, with AI development listed in that service, begins at a $95K to $165K band. Every other agency here prices a project once scoping is done.
An AI feature changes the budget in three places: connecting it to the data it answers from, structuring the content so answers are accurate, and testing it with real queries before launch. When the feature runs on an outside service, as TSTC's search does through Element 451 and Domestic & General's assistant does through Dialogflow, that service's own licensing sits outside the agency's fee.
