OpenAI's ChatGPT Work Now Learns Your Writing Style From Gmail, Slack, and Connected Apps

My take: OpenAI has added a feature to ChatGPT Work that learns how you write, not just how a generic AI writes. By connecting Gmail, Google Drive, Slack, and SharePoint, the model analyzes your actual messages, your recurring phrases, your tone, and even how you close emails, then applies all of that when drafting new text for you. You no longer need to paste writing samples or re-explain your voice before each session.

For anyone who creates content, writes proposals, or manages communications daily, this changes the process in a concrete way. Instead of spending time adjusting the tone of every AI-generated draft, the model already knows how you sound and returns something you can edit, not rewrite from scratch. I work with AI tools every day to build my projects, and the most tedious part has always been aligning the output with my own voice. A feature like this directly reduces that friction.

For now it is only available to ChatGPT Work subscribers, not in the standard version. If your company uses this tool for internal and external communications, it is worth asking: when did you last review what data your AI assistant has access to, and what privacy policy governs it?
