ChatGPT vs Perplexity
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.
Perplexity
An AI search engine that answers with citations — useful for quickly getting a sourced overview of a topic before you read the actual research.

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.
Perplexity
Ask a question, get a written answer with numbered links to the pages it drew on. Closer to a research assistant than a chatbot.
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.
Perplexity
Getting up to speed fast: what the current guidance says on a supplement, a new training method, or a coaching model a client mentioned. The citations tell you where to read next.
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.
Perplexity
A citation is not a good source. It will happily cite a blog post as confidently as a meta-analysis — click through before you repeat anything to a client.
Editorial comparison — nothing here is paid placement. Pricing changes often; treat the vendor’s own page as the truth. How we review
