Why this matters
Every office has someone who says ChatGPT is best, someone who swears by Claude, and a manager who has to decide which subscription to pay for and which one staff may use with client work.
Choosing on hype wastes money. Choosing without checking can put client data into a personal account the company does not control.
In this module you run a fair test on a real office task, score each answer on the facts, and see how to make the choice for your own team.
What you’ll build
You are Carla, the office manager at Ridgeline Insurance Agency. You paste the same task into ChatGPT, Claude, Gemini and Microsoft Copilot: a client reminder email plus a table of this week’s tasks.
You ask one of them for a change, then score every answer on three facts: the date and the VIN request, the phone number, and five rows in the right order. At the end you pick the one Carla should use at work, and see why.
What you need
- Nothing to start the practiceAll four assistants are practice copies inside the lesson.
- Free accounts, to run your own testchatgpt.com, claude.ai, gemini.google.com and copilot.microsoft.com all have a free version.
- Your work account, for client workUse the assistant your company already pays for and approves, for example Copilot with Microsoft 365 or Gemini with Google Workspace.
Concepts
3 ideas you’ll use in the practice.
A fair test means same task, same words
Paste the exact same task into each assistant. If you reword it for one, you are testing your prompt, not the tool.
Use a real task from your week, not a trick question. You want to know which one helps with your work.
Score on facts, not style
Style is taste: one writes longer, one adds a subject line. A wrong date or a made-up phone number is a real problem, and any of them can slip.
Pick two or three facts the answer must get right and check each one. That habit matters more than which tool you choose.
The best tool is the one you are allowed to use
For client work, the right choice is usually the assistant your company already pays for, because its business plan keeps your data out of model training and under the company’s control.
Never paste client details into a personal account. At home, try all four on your own tasks.
Practice
Do every step yourself in a practice copy of the real tool. It checks your work, and “Do it for me” finishes any step you get stuck on.
Do it for real
Now repeat it in your own account. Tick each step as you go.
Quick check
3 questions to check you’ve got it.
1. What makes the test fair?
- Rewording the task to suit each assistant
- Pasting the exact same task into each one
- Asking each one which assistant is best
Show the answer
Pasting the exact same task into each one. The same words in means the differences come from the tools, not from your prompt.
2. One answer has a nicer subject line, another has the wrong phone number. Which is the real problem?
- The subject line
- The wrong phone number
- Neither
Show the answer
The wrong phone number. Style is taste. A wrong fact reaches the client. Always check the facts.
3. Which assistant should you use for client work?
- Whichever is free
- The one your company pays for and approves
- Your personal account, because it is faster
Show the answer
The one your company pays for and approves. Business plans keep client data under the company’s control. Personal accounts do not.
