What it is
ChatGPT
A general-purpose AI assistant with chat, file uploads, voice mode and image generation. Most of your clients have already used it, which matters: they will not find it strange that you do too.
Microsoft Copilot
A free AI assistant on the web and mobile, and a paid add-on inside Microsoft 365 that can summarise Outlook threads, draft in Word and analyse Excel sheets.
Best for
ChatGPT
Everyday writing and thinking work. Save your voice, your offer and your coaching style as custom instructions or a project, and the drafts stop sounding like everyone else's.
Microsoft Copilot
Executive and corporate coaches working inside client organisations that standardise on Microsoft. Drafting in the same tools as the client saves a lot of reformatting.
Watch out for
ChatGPT
It is confident when it is wrong. Never let it be the source for a training, nutrition or medical claim, and check your plan's data settings before pasting anything a client told you in confidence.
Microsoft Copilot
The free app and the Microsoft 365 version have different data protections. If a client's company has rules about AI, follow theirs before yours.
