How do I get ChatGPT to write in my own voice instead of sounding like a robot?

You get ChatGPT to write in your voice by feeding it a sample of your writing and giving it a specific persona description, rather than just asking it to 'sound casual.' The trick isn't finding the perfect prompt — it's showing the AI what 'you' actually look like on the page. Start by pasting 2-3 paragraphs of something you've written into the chat. Then say: 'Analyze the tone, sentence structure, and word choice in this sample. Then write about [topic] in that exact style.' I've found this works far better than vague instructions like 'write conversationally.' For example, if your writing uses short, punchy sentences and dry humor, the AI will pick up on that pattern. If you tend toward longer, more thoughtful paragraphs with metaphors, it'll mirror that too. The key is giving it real material to work from. A second layer that helps: describe your voice in plain terms. Something like 'I sound like a skeptical journalist who's been doing this too long but still cares' gives the model a personality to inhabit. Combine that with the writing sample, and you'll get results that actually feel like you — not a corporate memo. One thing to watch for: ChatGPT sometimes overcorrects and makes things too casual. If that happens, just say 'a bit more formal, please' and it'll dial it back. For a deeper dive, see our guide on fixing AI writing that sounds too formal.
