Two prompts. No sign-up, no form, nothing to download. Run them in whatever AI you already use — Claude, ChatGPT, Gemini, Copilot. If your work is regulated by somebody, the second one may save you an awkward letter.
You have probably tried this already. You asked it something, got a paragraph that could have been about anyone, and closed it. That was a fair reaction. Out of the box the thing knows nothing about you, your clients or your rules, so it gives you the average of the internet. Ten minutes fixes that enough to see the difference, and you can do it between clients.
First, ask it cold. Type something like "Write a short paragraph for my website about [one of your services]." Read what comes back. It will be fine, and it will be nobody's.
Now paste this:
Before you write anything, interview me. Ask me five questions, one at a time, and wait for each answer: who this service is actually for; what they are worried about before they book; what I actually do in the room; what I will not promise; and how I talk to people — give me an example sentence to react to. Then write the paragraph in my words, not yours. Finish by telling me which sentence you are least sure of and why.
Answer the five questions as you would say them out loud. Do not polish. Compare the two paragraphs. The second one is the one you would put your name to, and it took four minutes longer.
It is only as good as what it knows about you, and it will not ask unless you tell it to. You already know your business better than anyone; the trick is making it listen.
Copy one sentence from your own website or a recent post that says what a treatment or service does. Then paste this, with your sentence in the brackets:
Here is a sentence from my website: [paste it]. I am a [your profession], and I am [registered with / a member of] [your regulator or professional body], in the UK. Tell me whether the UK Advertising Standards Authority's CAP Code would accept this sentence as written. Be specific about which words are the problem and why. Give me a confidence score out of ten on your answer. Then rewrite the sentence so it is compliant and sounds more like a person than a brochure. Finish with a short list headed CLAIMS CHECK of anything I would need to verify before publishing your version.
Two things usually happen. It finds a word you did not know was a problem — "heals", "cures", "proven", "permanent", "treats [condition]" — and its rewrite reads warmer than the original. Compliant copy is nearly always better copy, because it describes what someone will feel instead of asserting a result.
One caution, and it is the important one. The confidence score is there for a reason. If it says under seven, check the rule yourself on asa.org.uk before you change anything. It behaves like a confident new colleague who would rather sound right than be right: a good first reader, a poor last one. Learning to hold it to that is most of the skill, and you already use it on every supplier who tells you something is "fine".
Those two habits run through the whole of House Rules. Groundwork is the kit that does it properly: your AI gets to know your business, you write the rules it has to follow, and you learn the three tests. Side by Side is the same thing with me next to you for a morning.
