  • Write a one-page voice guide, and paste it in before you ask for any help.
  • Use AI for ideas, outlines, headlines and edits. Your stories and opinions are why people read.
  • Check every fact and link yourself, and tell readers how you use AI if they’d expect to know.

People read a newsletter or a blog because of the person writing it: your view, your stories, the way you put things. Let AI write the whole post and you get smooth, sensible prose that sounds like everyone else’s, which gives readers no reason to choose yours. Used well, though, AI can take on the slog around your writing, so you publish regularly without losing what makes it yours.

Start with a voice guide

Before you ask AI to help with a post, pin down how you sound. A voice guide is a short note you paste in at the start of every session, so the AI’s suggestions fit you rather than its own default style. It needs four things.

  • Three adjectivesHow you want to come across, such as warm, dry and practical. Three is enough to steer it.
  • Words you usePhrases you reach for, how you sign off, and habits such as short sentences or the odd aside in brackets.
  • Words you never useThe phrases that make you wince, such as “delve”, “unlock” or “in today’s fast-paced world”.
  • Two past piecesTwo posts you’re proud of, pasted in full, so it can hear your voice rather than guess at it.

You can ask the AI to draft the guide from your past pieces, then edit it until it sounds right to you. Many assistants let you save or set up a project, so you don’t have to paste the guide in every time.

Draft your voice guide

Here are two pieces I’ve written: [paste both in full]. Describe my writing voice as a one-page guide I could give to an editor. Include three adjectives for my tone; words, phrases and habits I use often; my typical sentence length; and how I open and close a piece. Then list ten words or phrases that would sound wrong coming from me. Quote my own lines as examples.

Works in any assistant, such as ChatGPT, Claude or Gemini. Edit what it gives you: you know your voice better than it does.

Let AI help around the writing

AI is useful for the jobs around a post: finding angles, shaping an outline, suggesting headlines and tightening a draft. It can’t supply the parts readers come for, because it wasn’t at the school gate on Monday and it doesn’t hold your opinions.

Ask AI forKeep for yourself
Ten angles on a topic you’ve chosenThe story of what actually happened to you
An outline to react toYour opinion, and what you’d tell a friend to do
Headline and subject line optionsThe final choice, and making sure the post delivers on it
A tighter, clearer edit of your draftThe jokes, the asides and the turns of phrase
Questions a reader might askWhat your readers actually replied last week
Plan a post, without writing it

Here’s my voice guide: [paste]. I want to write a post about [topic] for [who reads it]. Here’s my rough view and a story I want to tell: [your notes]. Suggest three ways to structure it, in five bullet points each, plus the question a sceptical reader would ask. Don’t write the post.

Pick the outline you like best, then write the draft yourself.
Edit against your voice guide

Here’s my voice guide: [paste]. Edit the draft below to match it. Cut repetition and tighten long sentences, but keep my phrasing, my jokes and my opinions. Don’t add facts, examples or claims of your own. Then list every change you made, and flag any line that doesn’t sound like the guide. Draft: [paste your draft]

For headlines and email subject lines, ask for ten options in your voice, then choose. Steer clear of : a headline that promises more than the post delivers costs you more trust than it earns in clicks.

AI can produce a statistic, a quote or a link that looks completely real and isn’t, a . It can also shift your meaning while “just tidying”. Before you publish:

  • Open every link and check it goes where you say it does.
  • Find every figure and quote at its original source. If you can’t, cut it.
  • Compare the edit with your draft, in case a careful sentence got bolder or a caveat went missing.
  • Read it aloud. Anything you wouldn’t say out loud doesn’t sound like you.

Tell readers how you use it

If your readers would expect to know, tell them. A line in your footer, such as “I write every post myself, and use AI to help with headlines and editing”, is honest and costs nothing. The more of the writing AI did, the more it matters to say so. Some publishing platforms have their own rules on AI content, so check those too.

A weekly routine

  1. Collect all weekKeep a running note of stories, readers’ questions and things that made you think. That’s your raw material.
  2. Plan with AIPick one idea, ask for angles and outlines, then choose the shape you like.
  3. Write it yourselfDraft it in your own words, however rough. Give this step the most time.
  4. Edit with AIPaste in your voice guide and ask for a tighter version that keeps your phrasing.
  5. Check and sendCheck every fact and link, pick a headline from its options, read it aloud, then publish.
