From first message to a useful Builder Report.

Instead of receiving a vague message and spending time chasing the basics, CosFox talks to your prospective customer, gathers the important project information and organises it for you.

Instead of receiving a vague message and spending time chasing the basics, CosFox talks to your prospective customer, gathers the important project information and organises it for you.

01

A customer starts an enquiry

A prospective customer starts a conversation with CosFox directly through your website and explains the work they are considering.

Customer

“We’re looking to replace our bathroom and possibly move the shower.”

02

CosFox understands the project

CosFox asks relevant follow-up questions, keeps uncertainty visible and builds a clearer picture of the proposed work without inventing missing answers.

Customer: “We’d like the bath removed and a walk-in shower instead.”

CosFox: “Do you know whether you want the shower to remain in the existing bath position?”

Customer: “Probably, but we’re not completely sure yet.”

03

CosFox creates the Builder Report

The conversation is organised into a concise Builder Report so you can understand the enquiry without reading through the entire chat.

Most website chatbots collect contact details and a message. CosFox is designed to understand the conversation around a construction project — asking useful follow-up questions, keeping track of what has actually been confirmed and highlighting information that may still need the builder’s attention.

What the builder receives

A clearer starting point: customer language organised into construction context, confirmed details and things still worth checking.

01 — CONSTRUCTION CONTEXT

Understands the project, not just the words.

CosFox follows the conversation in the context of the work being discussed, so its questions can respond to the project rather than following a generic contact form.

02 — UNCERTAINTY STAYS UNCERTAIN

“Probably” doesn’t become “confirmed”.

If the customer isn’t sure, CosFox keeps that uncertainty visible instead of quietly turning an assumption into a fact.

03 — THINGS WORTH CHECKING

Helps you spot what still needs attention.

CosFox can surface information that may be worth confirming before you decide how to proceed.

CosFox recommends. You decide.

CosFox helps organise the information and draw your attention to what may matter. You remain in control of the customer, the job and every commercial decision.
