ChatGPT vs Gemini
Two tools coaches often weigh against each other, compared on the same terms.
ChatGPT
The most widely used AI assistant — for drafting client emails, brainstorming session plans and turning messy notes into something a client can read.
Gemini
Google's AI assistant — the natural pick if your business already runs on Gmail, Google Docs and Calendar, since it can read and draft inside them.
Pricing
ChatGPT: Free tier with usage limits; paid plans raise them and unlock newer models
Gemini: Free tier; paid Google AI plans add higher limits and Workspace features

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.
Gemini
Google's conversational AI, built into the Gemini app and, on paid plans, into Gmail, Docs, Sheets and Drive. It can summarise a long email thread or draft a reply where you already work.
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.
Gemini
Coaches whose admin lives in Google Workspace. Asking it to find last month's check-in email or summarise a shared client doc saves more time than any standalone chat window.
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.
Gemini
The deeper integrations depend on your plan and account type, and they change often. Treat anything it pulls from your inbox as a draft to check, not a record.
Editorial comparison — nothing here is paid placement. Pricing changes often; treat the vendor’s own page as the truth. How we review
