Selected AI work

Different businesses.
Software built to fit.

A browser extension. A lead system. A medical workflow. Each built around the people who use it.

01 / Commerce & customer support

Customer support. Without switching tools.

We built a Chrome extension around a client’s Gorgias workflow. Their team defines reusable response guidance through a chat-like experience, without leaving the support tools they use every day.

Built for a client using Gorgias. Independent of Gorgias.

A customer needs your help with a delivery question.

02 / Sales & lead operations

Leads your team can act on.

For another client, we built a lead system that keeps inquiries and conversation context together. The team can follow up knowing what the person needs, instead of asking them to start again.

Medical workflows. With human review.

For a medical client, we built around their documented HIPAA requirements. Defined access and human-review points were part of the product, not details left until the end.

A few useful answers

Before we build.

Start with the business need. We will help you work through the product decisions.

What can a custom AI chatbot or assistant do?

A custom AI assistant can answer questions from approved knowledge, qualify leads, search internal systems, collect structured information, trigger workflows, schedule meetings, and hand conversations to a person. The right scope depends on the business outcome, available data, and the actions the assistant is allowed to take.

How is a custom AI assistant different from a generic chatbot?

A generic chatbot usually follows a fixed script or gives broad answers. A custom assistant is designed around your users, business information, rules, workflows, and product experience. It can find the right context, work with the tools your team already uses, and make its actions reviewable.

Can EXTFOX build an AI assistant as an MVP?

Yes. We can start with one valuable use case and build a working first version with the real interface, business information, one meaningful connection, and clear success checks. That gives founders something real to test before expanding the product.

Can the assistant connect to our CRM, calendar, support desk, or product?

Yes, when those systems provide a suitable way to connect. We design access and failure handling around each connection, then give the product only the actions it needs to do its job.

How do you reduce inaccurate or unsafe AI answers?

We combine clear instructions, approved business information, access rules, real examples, quality checks, and human review. No AI system is perfect, so the product must make uncertainty visible and provide a safe next step.

Do you support the assistant after launch?

Yes. We can review conversations, improve the product's behavior, add new connections, ship product changes, and keep quality visible as usage grows.

Let’s work together

Bring us the
hard part.

The product you want to launch. The workflow holding your team back. Let’s work through what it should do, who it should help, and the right first release.
