Client Overview

We’ve implemented this project for multiple agency clients who are ready to move beyond ad-hoc AI use to a safe, consistent, team-wide capability.

The Challenge

After an initial AI training rollout, our clients often find that prompting becomes a blocker to effective daily usage:

  • Prompting feels like extra work: people want to use AI more, but the time spent writing “good prompts” often cancelled out the benefit.
  • No shared knowledge of what works: teams don’t know which prompts colleagues are using, so everyone is effectively starting from scratch.
  • Inconsistent outcomes: even when AI is used, results can vary widely because there isn’t a consistent starting point for quality, tone, and structure.

Agencies need a way to make good prompting instant, repeatable, and shareable across the whole company.

Our Approach

AgencyTech treats prompting like a workflow asset - something to standardise and distribute the same way you would templates, brand guidelines, or operating procedures.

We focus on three things:

  1. Reduce friction to near-zero: so using AI feels faster than not using it
  2. Make high-quality prompts visible across the business: so knowledge doesn’t stay siloed with a few people
  3. Create a system that scales: so the library improves over time, not just at launch

The Solution

A database-driven Prompt Library app integrated into our client’s existing tech stack.

Key elements we deliver:

  • Role/department-based organisation: tag each prompt with the department(s) it’s useful for, so staff can find what’s relevant to them
  • Search + categories: to find the right prompt in seconds
  • Launch library of high-impact prompts:, based on agency workflows (emails, briefs, reporting insights, captions, proposals, summaries)
  • Brand voice: by referencing internal tone-of-voice documents to steer outputs without reinventing prompts every time
  • Submission + approval workflow: staff can contribute new prompts, with admin oversight, to maintain quality and consistency

The Results

Measured through system analytics and a short internal pulse survey.

  • 91% of survey respondents reported using the Prompt Library weekly (averaged across multiple clients)
  • Time saved: users report reclaiming time primarily through faster first drafts, fewer rewrites, and less “blank page” prompting
  • Quality uplift: respondents report outputs are more concise, more usable, and closer to client-ready on the first pass
  • Scalability: contributions increase over time, meaning the library improves as adoption grows

Key Takeaways

We turn AI prompting into a shared, searchable system - making high-quality outputs faster, more consistent, and scalable across the business.
