Do you ever struggle to get ChatGPT to emulate your tone, style, or voice? You may soon be able to connect your sent messages through third-party services so that ChatGPT can learn your writing style and better copy you in the future.

The feature is in testing with a select group of users, first spotted by Gael Breton on X before being reported by Bleeping Computer. Breton’s post shows the feature, with a description: “ChatGPT will write in your voice by referencing examples from your connected apps.”

In the example, it breaks down the connected apps into Documents, Email, and Messaging with Slack, Notion, Google Drive, and Gmail, all visible. It may also be able to use other connected apps via ChatGPT's tools for third-party services.

In reply to the post, another ChatGPT user said they’ve had access to the feature for weeks and found it to be a “game changer.” It’s unclear whether the app will read everything sent through the connected app once or periodically refer back to it to help adapt your writing style.

OpenAI has yet to officially announce this tool, but it often tests new ideas with select users ahead of launch. PCMag was unable to activate the feature during testing.

If you have the option, you’ll find it in Settings > Personalization > Writing. There’s a toggle called Reference my writing style, which, if available to you, can be toggled on or set up by pressing Set up writing style in the description.

OpenAI has already had a particularly busy September, including the release of its new Astra model and the disclosure of another incident involving GPT-powered agents. A group of researchers discovered that OpenAI agents had made over 15,000 edits to the German database DseWiki, a resource for coders.
