What happened
OpenAI is rolling out a new ChatGPT writing style feature that lets the chatbot study how you actually write and copy it. Instead of generating generic, robotic-sounding text, ChatGPT can now look at real samples of your writing — emails, Slack messages, docs in Google Drive — and match your voice: your word choice, your sentence length, even your habit of starting sentences with "honestly" or ending emails with "talk soon."
The option lives inside ChatGPT's personalization settings, tucked near the bottom under something like "match my writing style." Once turned on, you can point it at connected apps — Slack, Gmail, Google Drive — so it can pull in real examples instead of guessing from a short description you type in yourself.
One important catch: this isn't live for everyone yet. OpenAI is testing it with a limited group of users first, the way most ChatGPT features roll out before a full release. If you open your settings today and don't see it, that's normal — it's still being deployed in stages, according to reporting from PCMag. It's also worth noting this builds on something that already existed: ChatGPT's Custom Instructions, which have let people describe their preferred tone and style in a text box since 2023, as Zapier and Typetone both cover in detail. The difference now is that ChatGPT can learn your style from actual writing samples instead of you having to describe it in words.
What it means for you
Think of it like a new assistant who's read six months of your emails before writing their first draft for you — instead of one who's never met you and writes like a textbook.
• At work: Drafting a follow-up email to a client no longer means editing out ChatGPT's stiff, over-formal tone. It writes the way you'd write it, so you spend less time rewriting and more time hitting send.
• Running a business: Customer replies, proposals, and internal memos can all sound like they came from you (or your brand), even when a teammate or the AI drafted the first pass. That consistency matters when clients read ten messages from your company a month.
• Studying: Writing an essay or a discussion post gets easier to draft in your own voice rather than a version that reads suspiciously polished — which also matters if your school checks for AI-generated text.
• Creative projects: A newsletter writer, blogger, or social media manager can keep their signature tone across dozens of posts without manually re-explaining "be witty but not sarcastic" every single time.
• Side income: Freelancers who ghostwrite for multiple clients could, in theory, keep each client's distinct voice separate — useful if you're juggling five different "brand voices" in one week.
• At home: Even a thank-you note or a tricky message to a landlord can come out sounding like you actually wrote it, not like a form letter.
If you're testing AI tools for tasks like this without paying for anything yet, it's worth trying free AI tools at MyKreaTool alongside ChatGPT to compare how different tools handle tone and style before committing to one workflow.
How to try it right now
1. Open ChatGPT (free or paid, web or app) and log in.
2. Go to Settings → Personalization.
3. Scroll to the bottom and look for an option along the lines of "reference my writing style" or similar wording — it may say it's in limited testing.
4. If it's available to you, turn it on and connect the sources you want it to learn from (Slack, Gmail, Google Drive), or paste in a few writing samples directly if connections aren't offered yet.
5. Don't see it? Use the older, universally available option instead: go to Settings → Personalization → Custom Instructions and describe your style in plain language — for example, "write short sentences, casual tone, no corporate jargon, use contractions." This has worked for every ChatGPT user since 2023 and gets you 80% of the same result today.
6. Test it by asking ChatGPT to draft something you'd normally write yourself — an email, a caption, a reply — and compare it to how you'd actually phrase it.
Upsides and what changes
The obvious win is less editing. Right now, most people who use ChatGPT for writing spend real time stripping out the AI's default tone — too formal, too many bullet points, too many "I hope this finds you well" openers. A model that already writes like you cuts that step out.
It also lowers the bar for people who don't think of themselves as strong writers. You don't have to describe your style in words (which is hard — most people can't articulate their own voice) if the AI can just read examples and pick it up. And for businesses, it opens the door to keeping a consistent brand voice across a team, without every employee needing a style guide memorized.
Limitations
This is an early, limited rollout — not a finished, universal feature — so expect rough edges: it may not appear in your account yet, connected-app permissions (Slack, Gmail, Google Drive) raise real privacy questions about what OpenAI can access and for how long, and "matching your style" still means AI-generated text that you should read before sending, since it can misjudge tone in sensitive messages or copy bad habits along with good ones.
Conclusion
ChatGPT is moving from generic text generator to something closer to a ghostwriter who knows how you actually talk. It's not fully available yet, but the groundwork — Custom Instructions — already works for everyone today. Action for today: open ChatGPT's Personalization settings and write out three sentences describing your actual writing style, so you're already set up the moment the fuller feature reaches your account.
