ChatGPT Custom GPT Development in Salford

Building custom GPTs for Salford 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 Salford — 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 Greater Manchester?
Yes. We are based in Leicester, United Kingdom and work with clients throughout North West, including Salford and the surrounding Greater Manchester area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Salford businesses do you usually work with?
Production and media workflow tools, and design-led builds for a market with unusually high visual standards. Beyond that we work across Media & Broadcasting, Digital & Creative, Higher Education, Logistics and Construction.
Do you cover the areas around Salford?
Yes — we work throughout North West, including Manchester, Liverpool, Preston. Salford is an urban area of roughly 270,000+, and we take on work across the wider Greater Manchester region rather than the city boundary alone.
