The brief: answer visitor questions

The brief: answer visitor questions instantly and collect project enquiries, without paying for an AI API or risking a surprise bill.

What I built: a chat assistant on the Gemini API that explains the studio's services, guides visitors to the right section of the site, opens live demos and saves the visitor's contact details as a lead.

It is built to be safe in production:

Bot detection so scripts never reach the model

Per-visitor and site-wide rate limits

A hard daily usage cap that no number of devices can get around

A topic lock so it only answers questions about the business

A backup model and an email fallback, so real visitors never hit a dead end

Result: a 24/7 assistant that qualifies leads and runs at zero API cost.
