Microsoft Copilot is built into Word, Outlook, Teams and other workplace apps, so its text often appears in ordinary business documents rather than a chatbot window. Winston AI flags machine-written text, including text from Copilot. This page is for managers, HR teams and anyone who reviews workplace writing and wants to read results fairly.
AI text in everyday work
Copilot's drafts usually look like normal office writing: a status update in Outlook, a first pass at a policy in Word, a summary of a long email thread. Because the assistant sits inside the tools, many employees use it for routine writing without thinking of it as AI at all. In most workplaces that is fine, and often encouraged.
So the real question is rarely whether AI was used. It is whether it was used where it shouldn't have been: an assessed writing task in a hiring process, a performance self-review, or a document that needs a named author.
When authorship matters at work
- Hiring: writing samples and take-home tasks meant to show a candidate's own skills. See our page for recruiters.
- HR processes: grievance statements, self-assessments and investigation notes.
- Client deliverables: reports billed as expert work, where the client expects a person wrote them.
- Regulated writing: documents your industry requires a named person to write and sign off.
Reading results on business writing
Workplace writing is often formulaic by design: templates, standard openings, boilerplate legal text. Some of that can read as machine-like even when a person typed it. Focus on the passages that carry the substance, like the analysis or recommendations, and check whether they read as the author's own.
