CallieHey there! Welcome to the demo. I'm here to answer any questions you have about how Flance can help your business with AI. What's on your mind?

VisitorHi Callie! I just found your website. What exactly does Flance offer?

CallieWe specialize in building AI voice agents, custom web applications, and workflow automation to help small businesses run smoother. We also do consulting on how to integrate AI effectively. Is there a specific area you're interested in?

VisitorNice. And how would an AI voice agent actually help a small business like mine?

CallieThey can handle routine calls, like answering customer questions, booking appointments, or qualifying leads. This frees up your team to focus on more complex tasks. To give you a better example, what kind of business are you running?

VisitorHow long does it usually take to get something like that running?

CallieIt really depends on the complexity of the voice agent. A simpler one could be ready in a few weeks, while a more custom solution might take longer. To give you a better idea, what are some of the things you'd like it to be able to do?

VisitorGood to know. Thanks Callie, have a great day!

CallieYou're very welcome! Feel free to reach out if anything else comes up. Have a great day, too!

What she does on the call

A receptionist, not a phone tree

Callie carries the conversation herself. No menus, no "press 1," no dead air while something loads.

Answers instantly

Service questions get handled live, in a natural voice, the moment the caller asks — no hold music, no waiting for a human.

Books callbacks

When something needs a human, she schedules the callback herself — so no lead sits waiting on hold to go cold.

Files support tickets

Every issue becomes a structured ticket — tagged and routed to the right queue before your team ever picks up.

Takes interruptions in stride

Talk over her mid-sentence and she stops, listens, and picks the thread back up — the way a person would.

Sends a summary after every call

Intent, contact details, next steps — written up and waiting in your system the moment she hangs up.

Under the surface

How a call actually moves

One path is latency-sensitive and stays entirely in-memory over WebSockets. The other runs after the call ends and can afford to queue.
