UK Water Utility

The problem wasn't the volume — it was the inconsistency. Different writers, different interpretations of compliance guidelines, different registers. In a regulated industry, that has consequences: regulatory risk, reputational exposure, and review cycles that slowed everything down.

Three things made it hard to fix:

• No single tool could reach everyone. The comms team worked across email, internal portals, and document editors. A standalone web app would get ignored.
• Generic AI writing tools were useless. A water utility regulator cares about specific phrasing. Off-the-shelf tools couldn't be trained on the organisation's own guidelines.
• The compliance bar was zero-tolerance. Anything short of 100% compliant output wasn't good enough.

We built an AI writing co-pilot as a Chrome extension, deployable into any browser-based tool without an IT integration project. The model was trained on this organisation's own compliance guidelines, communication standards, and past approved communications.

The co-pilot does three things:

• Suggests compliant drafts based on communication type and relevant guidelines
• Scores existing drafts against the compliance ruleset in real-time
• Flags deviations with specific guidance on what to change and why

No new portals. No workflow changes. The AI appears in the tools people already use.

Writers stopped second-guessing phrasing. Senior reviewers stopped catching the same categories of errors every week. The review cycle shortened because fewer things needed to go back.
