Part 1: ChatGPT
Step 1: Give ChatGPT the task
If I started learning AI today, I'd do this first: give the same real task to all four big assistants and see for myself. You're Carla, the office manager at Ridgeline Insurance Agency. The task is a normal one: a reminder email to a client, and a table of this week's tasks.
I'm the office manager at Ridgeline Insurance Agency. Please do two things. 1. Write a short, friendly email to our client Mr. Okafor. His auto policy renews on November 1, and we need the VIN of his new car before then. He can reply to this email or call 555-0187. 2. Turn these notes into a table with three columns (task, owner, day), sorted Monday to Friday: renewals call list - Jess - Tue; update office hours on website - me - Wed; order printer toner - Sam - Mon; quarterly staff meeting agenda - me - Thu; mail holiday card list - Jess - Fri
Step 2: Send it
Send it.
Part 2: Claude
Step 3: Open Claude
A friendly email, and a table sorted Monday to Friday. Now the same thing in Claude. Switch tabs.
Step 4: Same task, word for word
Same task, fair test.
I'm the office manager at Ridgeline Insurance Agency. Please do two things. 1. Write a short, friendly email to our client Mr. Okafor. His auto policy renews on November 1, and we need the VIN of his new car before then. He can reply to this email or call 555-0187. 2. Turn these notes into a table with three columns (task, owner, day), sorted Monday to Friday: renewals call list - Jess - Tue; update office hours on website - me - Wed; order printer toner - Sam - Mon; quarterly staff meeting agenda - me - Thu; mail holiday card list - Jess - Fri
Step 5: Send it
Send.
Part 3: Gemini
Step 6: Open Gemini
Claude added a tip about where to find the VIN. Helpful, but it's something you didn't ask for, so check it. Now Gemini.
Step 7: Same task again
If Gemini asks to connect Gmail, you can say no thanks and ask it to answer here in the chat.

His auto policy renews on November 1, and we need the VIN of his new car before then. He can reply to this email or call 555-0187. 2.

Step 8: Send it
Send.
Part 4: Microsoft Copilot
Step 9: Open Copilot
Gemini added your job title and a phone number to the signature. Last one: Microsoft Copilot, on a work account.
Step 10: Same task in Copilot
Notice the Work badge next to your name. Work means Copilot can use your company's files and email, if your company allows it.

Step 11: Send it
Send.
Part 5: Ask for a change
Step 12: Ask for a change
Copilot's is the shortest so far. Here's the real secret: the second message matters more than which assistant you picked. Ask for a change.
Step 13: Send it
Send. Any of the four would do this. What matters is that you check the facts every time.
Part 6: Compare and choose
Step 14: Open your scorecard
Now score them the boring way, on facts. Switch to your scorecard. For each answer: the date and the VIN, the phone number, and five rows in the right order.
Step 15: Check ChatGPT
ChatGPT got all three.
Step 16: Check Claude
Claude too, plus that extra tip you should double-check.
Step 17: Check Gemini
Gemini, all three.
Step 18: Check Copilot
And Copilot. On a task like this, all four do the job. The differences are mostly style.
Step 19: Choose the one you can use at work
So which one should you use at work? The one your company already pays for and allows, because your company data stays under its rules. Ridgeline runs on Microsoft 365, so Carla picks Copilot Chat. On Google Workspace, that's Gemini. At home, try the free plans and keep the one you like.
Now do it yourself, free
Reading the steps is a start. Doing them is how it sticks. The interactive lesson puts you in a practice copy of ChatGPT, Claude, Gemini and Copilot: you do every step yourself, it checks your work, and “Do it for me” finishes any step you get stuck on. Nothing touches your real accounts.

ChatGPT
0:00 If I started learning AI today, I'd do this first: give the same real task to all four big assistants and see for myself. You're Carla, the office manager at Ridgeline Insurance Agency. The task is a normal one: a reminder email to a client, and a table of this week's tasks. Paste it into ChatGPT.
0:17 Send it.
Gemini
0:18 A friendly email, and a table sorted Monday to Friday. Now the same thing in Claude. Switch tabs.
0:23 Paste exactly the same words. Same task, fair test.
0:26 Send.
0:27 Claude added a tip about where to find the VIN. Helpful, but it's something you didn't ask for, so check it. Now Gemini.
0:34 Paste the task. If Gemini asks to connect Gmail, you can say no thanks and ask it to answer here in the chat.
0:40 Send.
Microsoft Copilot
0:41 Gemini added your job title and a phone number to the signature. Last one: Microsoft Copilot, on a work account.
0:47 Notice the Work badge next to your name. Work means Copilot can use your company's files and email, if your company allows it. Paste the task.
0:55 Send.
Ask for a change
0:56 Copilot's is the shortest so far. Here's the real secret: the second message matters more than which assistant you picked. Ask for a change.
1:03 Send. Any of the four would do this. What matters is that you check the facts every time.
Compare and choose
1:08 Now score them the boring way, on facts. Switch to your scorecard. For each answer: the date and the VIN, the phone number, and five rows in the right order.
1:16 ChatGPT got all three.
1:18 Claude too, plus that extra tip you should double-check.
1:21 Gemini, all three.
1:22 And Copilot. On a task like this, all four do the job. The differences are mostly style.
1:28 So which one should you use at work? The one your company already pays for and allows, because your company data stays under its rules. Ridgeline runs on Microsoft 365, so Carla picks Copilot Chat. On Google Workspace, that's Gemini. At home, try the free plans and keep the one you like.

The test
You're Carla, the office manager at Ridgeline Insurance Agency, a made-up agency. The task is a normal Monday one: write a short, friendly email reminding a client that his auto policy renews on November 1 and that the agency needs his new car's VIN, and turn five scribbled notes into a table of this week's tasks (task, owner, day), sorted Monday to Friday.
You paste exactly the same words into ChatGPT, Claude, Gemini and Microsoft 365 Copilot Chat, ask Copilot for a shorter version, and then score each answer on three facts: November 1 and the VIN, the reply-or-call option with the right number, and five rows in the right order.
What the comparison shows
- On a task like this, all four get the facts right. The answers in the lesson are written to show typical differences, and real answers change every time you ask.
- The differences are style: subject lines, length, how formal the greeting is, and whether the assistant adds something you didn't ask for (in the lesson, Claude adds where to find a VIN and says so). Anything extra is something to check.
- Your second message matters more than the brand. Asking for 'under 60 words, same facts' fixed the length in one try.
Which one should you use at work?
Use the assistant your company already pays for and allows, because your company's data then stays under its agreements and settings. If you're on Microsoft 365, that's usually Microsoft 365 Copilot Chat, which can switch between Work (your company's content, if allowed) and Web. On Google Workspace, it's Gemini. Some companies buy ChatGPT or Claude business plans. Don't paste client or customer details into a personal account.
At home, all four have a free version. Try them on a task you really do every week and keep the one whose style you like best.
A fair test for your own team
Pick one task you do every week, write it once, and paste the same words into each assistant on the same day. Score on facts first (dates, names, numbers, nothing invented) and style second. Then ask each one for one change, because that's how you'll really use it. Repeat in a few months: these tools change often.
Try it yourself, free
Reading the steps is a start. Doing them is how it sticks. The interactive module walks you through every click in a practice copy of ChatGPT, Claude, Gemini and Copilot, checks each step, and never touches your real accounts.

- Is this free?
- Yes. Stepthrough is free, and ChatGPT, Claude, Gemini and Microsoft Copilot all have free versions you can try the same test in.
- Which AI is the best?
- For everyday writing and tables, they're close. Pick the one your company already pays for and approves for work, then get good at asking for changes and checking facts.
