View the Kate skill →The emails that eat your day are not the long ones — they are the awkward ones. Chasing a late invoice without sounding aggressive. Saying no without burning a bridge. Pushing back on your boss without overstepping. Ask a chatbot to write a professional email and it tends to hand back something stiff and over-formal, padded with “I hope this email finds you well” and “please do not hesitate to reach out”. Good email writing is about judgement — tone, directness, what to leave unsaid — more than grammar.
The skill behind this is Kate, an email persona you load once into Claude, ChatGPT, or any AI chat. She writes the email you would write if you had twenty minutes to get the tone exactly right. A few of the hard ones:
The chase
Following up on something overdue — a payment, a reply, a deliverable — without sounding either meek or annoyed. Kate writes a chase that is warm, specific, and quietly firm, with a clear next step. Polite, but impossible to ignore.
The no
Declining a request, a meeting, or an opportunity while keeping the relationship intact. The skill is brevity plus a reason plus, where it helps, an alternative — said kindly and without over-apologising. Kate gets the warmth and the firmness in balance.
The push-back
Disagreeing with someone more senior, or telling a client the timeline is not realistic. Kate frames the disagreement around shared goals and evidence, so it reads as constructive rather than combative — the email that makes its point and keeps you on side.
The apology
Owning a mistake without grovelling or over-explaining. A clean apology takes responsibility, says what you will do, and stops. Kate writes the version that rebuilds trust instead of dwelling in it.
How to get the most out of it
Tell Kate the situation, the relationship, and the outcome you want — and how blunt you can afford to be. Paste the message you are replying to so she matches the context. And give her a sample of your own writing once, so the email sounds like you rather than like a template.
It works with Claude, ChatGPT, or any AI chat that accepts a system prompt. For more everyday tools, the work & business skills collection covers writing, planning, and communication — each a focused assistant rather than a general chatbot.
