Custom GPT Development in Ely
Building custom GPTs for Ely teams — a configured assistant with your instructions, your reference documents and, where useful, actions that call your own systems. The honest framing is that a custom GPT is a fast way to get something useful in front of people, and a poor place to put anything you would not email to a colleague.
Why this comes up
The problem
Everyone is prompting from scratch, badly and differently. The same task produces different quality depending on who asked, and the good prompt someone worked out lives in their notes.
What you get
What we deliver
- Instructions written and tested against the task rather than guessed at once
- Reference documents attached, so answers draw on your material
- Actions calling your own APIs where the assistant needs live data
- Sharing scoped to your workspace, not published where it need not be
- A tested set of example inputs, so quality is checked rather than assumed
- An honest assessment of whether this should be a custom GPT at all

Custom GPT Development in Ely — common questions
- When is a custom GPT the wrong choice?
- When it needs to handle personal or confidential data, integrate deeply with internal systems, or be embedded in your own product. A custom GPT is convenient precisely because it is lightweight, and those requirements point at a proper API integration instead.
- Who can see the documents we attach?
- Anyone who can use the GPT can generally get at the reference material through it, whatever the instructions say. Treat attached documents as visible to every user of that GPT, and scope sharing accordingly.
- Can it access our systems?
- Yes, through actions that call your APIs, with authentication. It works well for reads — looking up a record, checking a status. For anything that changes data, the same caution applies as to any automated caller of your API.
- Why does the same task give different results?
- Usually because the instruction is ambiguous rather than because the model is unreliable. Most of the improvement in a custom GPT comes from specifying the output format and the edge cases precisely, which is unglamorous and effective.
- Do you work with businesses across Cambridgeshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout East of England, including Ely and the surrounding Cambridgeshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Ely businesses do you usually work with?
- Grower and packhouse systems handling seasonal labour, traceability and supermarket compliance requirements. Beyond that we work across Agriculture, Food Production, Tourism & Heritage, Retail and Logistics.
- Do you cover the areas around Ely?
- Yes — we work throughout East of England, including Cambridge, Peterborough, Norwich. Ely is an urban area of roughly 20,000+, and we take on work across the wider Cambridgeshire region rather than the city boundary alone.
