What we build

We plan, build and test custom AI tools, from assistants that answer from your own documents to AI connected to the software you already use. Each one is meant to take your project from an idea to a tool your team can rely on and use every day.

Answers from your own documents

We build assistants that answer questions from your own documents and records, so the answers come from your information. This is often called RAG. We prepare your documents, split them into searchable pieces and set up search with tools like Pinecone, Weaviate, Qdrant and pgvector. Before we build, we agree with your team which documents to use, who may see what and the test questions we’ll check it against.

Preparing and splitting your documents
Choosing and tuning how questions are matched to documents
Setting up the search database
Search by meaning and by exact words
Search that updates as your documents change

Connecting AI models to your business

From connecting an AI model to your software to training it further on your own examples, we help you get the most out of AI models. We work with models from OpenAI and Anthropic, open-source models and privately hosted ones to find the right fit. We compare a few models on agreed tasks and measure accuracy, speed and running cost before choosing one.

Comparing and choosing models
Writing and testing instructions (prompts)
Extra training on your own examples
Using several models together
Keeping running costs down

Safety limits and checks

We set what an AI tool is allowed to do, test its answers and give people a way to review its work. Who can use it, how its answers are checked and how it’s watched are all planned around how you’ll really use it.

Filtering what goes in and what comes out
Checks aimed at catching made-up answers
Testing for unfair or biased answers
Access rules, and when a person must review
Monitoring and alerts

Complete AI apps

We build the whole app, from the screens people use to the systems that run the AI behind them. We build it to be fast and reliable, with checks we agree with you, and room to grow with your business.

Screens built with React and Next.js
AI systems built with Python and Node.js
Answers that appear as they’re written
Logins, and who can see what
Automatic testing and releases

Cloud setup and hosting

We set up cloud hosting built for AI work on AWS, Google Cloud and Azure. From the graphics-card servers (GPUs) that AI needs to running your models day to day, we tune it for speed, cost and reliability.

Managing GPU servers
Running models quickly and at lower cost
Kubernetes and containers
Setup written as code (Terraform, Pulumi)
Cost tracking and automatic scaling

Tools made for your business

Every business is different. We build AI tools for your own problems, whether that’s automating work inside your business, building AI agents that carry out tasks, or creating a new AI-powered product.

AI agents that carry out tasks
Automating repeat tasks
Moving and cleaning up data
Adding AI to older systems
Quick trial versions

Start with the work you want to improve.

Each project has an agreed scope, a way to check the result and someone in charge of it once it’s running.

Customer questions and follow-up

Give customers a useful answer and your team a clear next step.

Answers come from information you have approved
Takes down the customer’s details and passes them to a person
Can connect to your customer list or booking calendar if that helps

Start with the questions your team answers every day.

Automating a repeat task

Turn a task your team does over and over into one that runs on its own.

Write down the task step by step, from start to finish
Connect the programs your team already uses
Add checks, a plan for odd cases and a record of what happened

Start with one task you do often and can measure.

Ask about this: Automating a repeat task

Connecting your programs

Stop typing the same information into two or three programs.

Link your programs so information moves between them
Check each update and catch the ones that fail
Decide which program has the final say on each record

Start with one connection and clear rules for updating records.

Ask about this: Connecting your programs

Answers for your team

Help your team find answers in the information you already have.

Search approved documents by asking in everyday words
Show where each answer came from, and only to people allowed to see it
Test the answers and agree who keeps the documents up to date

Start with one useful set of documents and real staff questions.

Ask about this: Answers for your team

Paperwork and reports

Turn incoming documents into information your team can use.

Pull the details you need out of documents
Send anything the tool isn’t sure about to a person to check
Make reports, or pass checked details into another program

Start with one type of document and an agreed way to check it.

Custom business apps

Ongoing care, with a clear scope.

Choose the checks, upkeep, support and improvements your tool needs.

Agreed support hours and how fast we reply
A spending limit, and a clear view of what you pay
A set amount of content updates and changes

Your written quote says who looks after what, and what other companies charge, before you commit.

How we work

A clear process from first conversation to launch.

Getting to know your business
We start by learning about your business, your data and your goals. In detailed talks with you and your team, we find where AI could help most.
Planning the design
We plan a design that balances speed, cost and ease of upkeep. Every technical decision is written down and reviewed with your team before we write any code.
Building in short rounds
We build in short rounds and check in with you often. You see working software early and often, not a big reveal after months of silence.
Launching and improving
We launch with monitoring, testing and a way to undo changes if something goes wrong. After launch, we keep improving speed, cost and ease of use.

Ways to work with us

Start with one focused project, get ongoing help, or ask for advice.

One project

Quoted for an agreed scope

A fixed scope and timeline, good for a first version, a trial or a clearly defined job. We plan it, build it and hand it over with full write-ups and a walk-through for your team. Your written quote sets out how we’ll check the work, the launch plan and the running costs.

Ongoing help

An agreed monthly plan

Ongoing building, improvements and support, for teams that need regular AI help without hiring full-time staff. The agreement sets the hours, the support you can expect and the changes included.

Advice

Priced separately

Guidance on your AI plans, reviews of how a system is built and help choosing tools and hosting. A free 30-minute call helps pin down the problem. A deeper review, if needed, has its own scope, results and agreed price.

A price for an agreed result.

We quote once we understand how the work is done today, which programs you use and how much of it there is. Each written quote shows three costs separately.

Building it

A fixed price to build, test, write up and launch what we agreed. What’s included and how we’ll check it are written down.

Optional care

A monthly plan for the support and upkeep you choose, with a set amount of changes included.

Other companies’ fees

The AI service, other platforms and web hosting charge their own fees. We explain these separately and agree a spending limit or budget.
