A simple way to choose based on what you're doing.
when you want a flexible, do-it-all assistant for brainstorming, quick drafts, and exploring ideas — or you want to try the newest AI features.
when the writing has to be polished and on-brand, or you're working with long documents — member letters, reports, summarizing a long PDF, or careful editing.
when you need current information from the web or you're working inside Google Docs or Gmail and want AI right where your files already live.
The honest answer: start with whatever your office already has access to. Learn one tool well using the 4-part framework before worrying about the rest — the prompting skills transfer directly to all three. And whichever you choose, never paste confidential member data (IDs, home addresses, anything private) into any AI tool.
