AI sales and customer service for fitness studios.
Zenn builds a Claude-powered sales and customer-service assistant for fitness studios. It answers website visitors with the studio's own information, recommends the right package, starts the pre-registration and hands over to the team when a person should answer. We build it inside our own studio in Istanbul.
What it does
Answers instantly
Packages, make-up rules, live classes, payment options: it answers visitors around the clock from what the studio has published.
Moves visitors to sign-up
It asks about goals and schedule, recommends a class, format and package, and opens the pre-registration form with those choices.
Doesn't make things up
No prices, times, promotions or coach names that aren't on the site. When it doesn't know, it says so.
Hands over to people
It never comments on health matters; it connects the visitor with the team by WhatsApp, phone or e-mail.
See how it talks
The product's real interface with four conversations written to the assistant's rules. Pick a scenario.
- 1
Your information is the source
Packages, rules, FAQs and contact details on your site become a single knowledge text. That is all the assistant knows.
- 2
Claude talks, the server enforces the rules
Claude writes the answers. Health topics and card, IBAN or national ID numbers are caught on the server before anything reaches the model.
- 3
Sales and support reach your team
Ready visitors land on the pre-registration form with the right choices; when a person is needed, the conversation goes to your team.
Zenn Assistant
AIScripted demo: these conversations are pre-written, not live AI responses.
Trust and privacy
The assistant's rules aren't only written in a prompt: they're enforced in code and checked by automated tests.
Says it's an AI
Every conversation opens by saying the assistant is an AI and offering a human.
No conversation logs
Message content is never logged; only counts such as messages, tokens and duration.
Sensitive data stays out
Health topics and payment or ID data are caught on the server and routed to a person, never to the model.
Runs within limits
Turkish and English only, with caps on message length, conversation length and requests per IP.

Built with Claude
Claude Code
This website was built with Claude Code, Anthropic's coding agent, by our two-person software team.
Claude
The assistant is designed to run on Anthropic's Claude models. Its system prompt is generated from the studio's published content, and its behaviour rules are checked by automated tests.
