ChatGPT Can Now Learn How You Write From Your Email. Don't Connect It Yet.

OpenAI put out a note Monday saying ChatGPT Work can now learn how you write. Connect your Gmail, Google Drive, Slack, or SharePoint, and it'll read your emails and files, pick up your go-to phrases and how you sign off, and start drafting things that sound like you instead of like a robot.

I've spent the better part of two years telling business owners that voice is the whole problem with AI writing. The grammar's fine. The spelling's fine. It just doesn't sound like the guy who runs the shop, and customers can tell in about four words. So on paper this fixes the exact thing I complain about.

And I'd still tell you to slow down before you flip the switch.

What you're actually connecting

The feature doesn't learn from what you type into ChatGPT. It learns from the apps you connect. That means your inbox, and your inbox isn't only the emails you wrote. It's everything anybody ever sent you. The customer who told you about her husband's diagnosis so you'd hold the appointment. The supplier quote you promised not to share. Payroll questions from your bookkeeper. The back and forth with your lawyer about the guy who slipped in the parking lot.

OpenAI says access follows whatever permissions the connected account already has, and you can disconnect it from settings anytime. Both true. But the real question is whether you meant to plug that much in to begin with. To teach a tool how you say "sounds good, thanks" you don't need it reading three years of other people's mail.

It learns from whoever's typing

Something else to think about. It learns your style from what's in the account. If your office manager sends half the emails from the main address, it learns her. If your sent folder is mostly one line replies from your phone, that's the voice it picks up, which is probably fine, but it's not going to write your proposals that way. And if you connect a shared inbox, it's learning a blend of four people, and the drafts will sound like a committee.

This is a paid ChatGPT Work feature, on the web, so it's aimed at the business plan crowd, which for most of you means you plus a couple of people. That's exactly the setup where a shared login and a shared inbox are common, and exactly where this gets muddy.

The version I'd do instead

What we do in the workshops takes about twenty minutes. Pull ten emails you wrote that you'd be comfortable reading out loud in front of a customer. Not your best ones. Your normal ones. Paste them into a chat and say "this is how I write, match it." Then keep that chat open and use it for drafts. It picks up the sign-off and the short sentences and the "Hey man" or the "Hi Karen," and you handed over exactly ten emails, all of them yours, all of them ones you chose.

That's not as slick as a toggle in settings. It also doesn't quietly hand a third party the contents of every email your customers ever trusted you with.

If you do want ChatGPT connected to your inbox for other reasons, and there are good ones, like searching old threads or summarizing a long chain, then make that decision on purpose, with the people in your shop who'd be affected, and write it into your AI policy. Don't let a writing style feature be the reason you decided.
