It’s true. Chat is now better at not using em dashes—if you instruct it via custom instructions. You can find your custom instructions under your personalization settings.

In the workshops I give about AI writing/detection I point out that the tech companies have a strong incentive to fix whatever the public doesn’t like about AI writing style. So any ‘hallmarks’ you learn to spot—which already aren’t reliable—will be obsolete within months. Save your energy, and more importantly save yourself from the very real risk of linguistic discrimination, and stop looking for AI hallmarks.

I don't understand what OpenAI and ChatGPT are doing. To me, this is brand suicide. This reinforces the idea that using #AI is either lazy or cheating. There's nothing wrong with em dashes. People use them all the time. I've been using them for years. Microsoft Word automatically inserts them into text when you type. It's part of grammar. By doing this, they are only further adding to the stigma surrounding the use of AI for professional work. What's the point of all of this, then? What's the strategy behind this trillion-dollar moonshot, if you are telegraphing that AI use at the office is something to hide? This is the OPPOSITE of what AI needs right now as a category. It needs widespread, enterprise adoption. It needs the #SMB market to buy subscriptions and use it. How does any of this help with that? People use ChatGPT at work. They should be doing it openly, but if they ARE hiding it, THAT is the brand war that OpenAI should be fighting. Not freaking em dashes.

Is the em dash drama finally over? For ChatGPT regulars, it might be the most controversial topic of 2025. If you use it to rewrite emails, you know the move: clean copy, then a parade of em dashes. OpenAI's apology made me laugh, especially “You can find your custom instructions under your personalization settings.” Still skeptical this will actually fix it. I am all in on AI, but I should not need a mini system prompt just to tame dramatic punctuation. One simple toggle that says “Never use em dashes again” would do the trick. Even with quirks, AI is still the fastest way from messy draft to clear message. If you are not using it yet, why not? #AIWriting #ChatGPT #ContentStrategy #PromptEngineering

Nice improvement. With custom instructions, Chat can avoid things like em dashes and match your preferred tone more closely. Personalization settings are where to start.
