ChatGPT Custom GPT Development in Edinburgh

Building custom GPTs for Edinburgh organisations, with one property that should govern what goes into them. The instructions and uploaded files are available to anyone who can use the GPT — a determined user can generally get them out — so nothing should be included that you would not be content for every user to read directly.

Why this comes up

The problem

Confidential pricing rules were put into a custom GPT's instructions, and any user can persuade it to recite them.

What you get

What we deliver

  • Content included on the assumption that users can retrieve it verbatim
  • Instructions written as behaviour, with the knowledge kept in uploaded files
  • Files curated and current, since a stale document produces confident wrong answers
  • Sharing scope set deliberately — a team, the organisation, or wider
  • Actions connected to real systems where a lookup adds genuine value
  • An owner assigned, because an unmaintained GPT degrades without anyone noticing

ChatGPT Custom GPT Development in Edinburgh — common questions

Can users see the instructions?
Assume so. There are ways to discourage it and none that reliably prevent a determined user from extracting the instructions or the contents of uploaded files, so the safe design is to include only what you would be comfortable publishing to its audience.
What makes a custom GPT worth building?
A repeated task with consistent context. If a team keeps pasting the same background before asking similar questions, packaging that is genuinely useful — whereas a GPT built to look impressive with no repeated task behind it goes unused.
How current do the files need to be?
As current as the answers need to be. Uploaded documents do not update themselves, so a GPT built on last year's policy will answer confidently from it — which is why an owner and a review date matter more than the initial build.
When should we build something custom instead?
When you need control over data, auditability, or integration beyond what actions provide. Custom GPTs are excellent for packaging context for internal use and are not the right home for anything customer-facing or governed.
Do you work with businesses across City of Edinburgh?
Yes. We are based in Leicester, United Kingdom and work with clients throughout Scotland, including Edinburgh and the surrounding City of Edinburgh area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Edinburgh businesses do you usually work with?
Financial services and data-led work, plus seasonal systems that have to absorb enormous August load without falling over. Beyond that we work across Financial Services, Technology, Tourism, Higher Education and Data Science.
Do you cover the areas around Edinburgh?
Yes — we work throughout Scotland, including Glasgow. Edinburgh is an urban area of roughly 540,000+, and we take on work across the wider City of Edinburgh region rather than the city boundary alone.
