Models

Any model, chosen for the job

Each AI company is ahead at something different, and the lead changes every few months. We work with all of the main ones, test on your real tasks, and keep the model a setting you can change rather than something built into the app.

Claude Anthropic

Strong on long documents, careful reasoning and tool use. Claude Code is the coding agent we build with most.

ChatGPT OpenAI

The widest ecosystem, with voice, image and file features that suit customer-facing assistants.

Codex OpenAI

OpenAI’s coding agent. We use it alongside Claude Code to build and review software.

Grok xAI

Can draw on what is being posted on X right now, which suits social listening and news-driven work.

Kimi Moonshot AI

Long-context models with open weights, so they can run in your own cloud account when data must stay in-house.

Product names belong to their owners. We are an independent agency, not a partner of these companies.

What we build

AI agents we build

Customer support agent

Answers questions from your own documents, website and policies, and hands the conversation to a person when it should.

WhatsApp and website assistant

Qualifies enquiries, answers pricing questions and books calls straight into your calendar.

Back-office agent

Reads invoices, orders, CVs or forms, pulls out the fields and updates your CRM, ERP or spreadsheet.

Research and reporting agent

Collects figures from your tools and the web and drafts the weekly report for a person to check.

MCP servers

Connect your own systems to Claude, ChatGPT and other assistants, so your team can query them in plain language.

AI inside your website or app

Search that understands questions, content drafting in your admin, and recommendations, added to a Wix site or a custom web app.

Why us

Why businesses hire us to build AI agents

Any model, no lock-in

We are not tied to one AI company. We choose the model for each task on accuracy, speed, running cost and where your data may go, and build so it can be swapped when a better one ships.

Built fast with AI, checked by people

We build with Claude Code and Codex, which lets a small senior team move quickly. A senior engineer reviews every change before it ships.

Proof you can check

This website is our own build. In October 2026, working with Claude Code, we cleared 129 issues across it in two days and took its Ubersuggest site audit score from 72 to 100.

What we changed

We connect it to what you have

An agent is only useful when it reaches your real systems. We have built 272+ websites and apps, so connecting one to your site, CRM or database is familiar work.

Our free tools show the same work in public: the MCP endpoint checker tests whether a site offers an MCP server that AI agents can connect to, and the AI crawler checker shows which AI bots can read a site.

How it starts

How an AI agent project runs

  1. Free 30-minute call

    Tell us the job you want done. We tell you whether AI is the right tool, which model we would start with, and roughly what it would cost to run.

  2. Prototype on your data

    A working version on a sample of your real documents or data, so you judge it on your own cases, not a demo.

  3. Production build

    Connections to your systems, guardrails, human approval where mistakes matter, logging and a monthly spending limit.

  4. Launch and improve

    We test answers against real cases, watch running costs, and move to a better or cheaper model when one ships.

AI agents · Questions

AI agent development: common questions

Which AI model is best for building an AI agent?

There is no single best model. Claude is strong on long documents, careful reasoning and coding; OpenAI’s GPT models have the widest ecosystem; Grok can draw on live posts from X; and Kimi offers open-weight models you can host yourself. We test two or three on your real tasks, choose on accuracy, speed and running cost, and build so the model can be changed later.

How much does it cost to build an AI agent?

It depends on what the agent connects to and how much testing and human review the job needs, so we quote after a free call against a written scope. There are two costs: the build, paid once, and model usage, paid monthly to the AI provider. We estimate the monthly cost before you commit and cap it with a spending limit.

How fast can you build an AI agent?

Because we build with AI coding tools such as Claude Code and Codex, a working prototype on your own data usually takes days rather than months. A production agent takes longer, because connecting your systems, testing against real cases and adding human review is where the effort goes. You get a dated plan after the first call.

Will my data be used to train AI models?

Not in the way we build. We check each provider’s data terms and use API plans that exclude your data from model training. When data must stay in-house, we can run an open-weight model, such as Kimi, in your own cloud account.

Can you add AI to my existing website or software?

Yes. Most of our AI work connects to something that already exists: a Wix website, a custom web app, a CRM or a shared drive. We add the agent alongside your current systems rather than replacing them.

What happens when the AI gets something wrong?

It will sometimes, so we plan for it. We test against a set of real questions before launch, show the source behind each answer, send anything with real consequences to a person for approval, and log every conversation so mistakes are found and fixed.
