The first answer that sounds right often wins by default. When you compare ChatGPT and Claude in separate tabs, the setup can drift before you notice. One service gets a cleaner prompt, a different file, or an extra follow-up. Add Gemini and the differences become harder to trace. The result may look like a model comparison when it is really a comparison of three slightly different tasks.
A fairer test is less dramatic. Choose a task you already need to finish, freeze the input, and decide in advance how you will check the answer. The point is not to crown a winner. It is to find out which response you can use after the important claims have been checked.
SuperCompareAI lets you send one question to selected AI services in one browser flow. That keeps the dispatch step consistent while you compare the answers.

Make the test repeatable
Use a task with a visible finish line: a planning memo, a code review, a research outline, or a rewrite with a fixed audience and length. A clever puzzle can produce a memorable answer, but it says little about the work waiting on your desk.
Before asking anything, note:
• What the answer needs to help you decide or deliver
• Which facts, files, links, and examples all three services may use
• The audience, format, length, and other limits
• Which claims need a source or a separate check
• What a usable answer would look like for this task
Then write one prompt that you can reuse:
Prompt example
I am working on [specific task]. Use only the context below. Give me a recommendation, the assumptions behind it, two risks, and the next action. Mark any claim that needs external verification.
Send the same prompt, context, and files to ChatGPT, Claude, and Gemini. If one service cannot accept a file or link, record that difference. Do not quietly rewrite the input to make the result look fair.
Read the answers in two passes
On the first pass, read all three answers without picking a favorite. On the second pass, check the details that can change your next action:
• Did the answer follow the requested format and limits?
• Did it use the supplied context, or drift into generic advice?
• Which claims, assumptions, and links still need checking?
• Can you act on the recommendation without filling in missing pieces?
• Did the answer explain uncertainty where it mattered?
• What changed after the same follow-up question?
Confidence is not evidence. Agreement is not proof. A model may sound more useful because it gives a direct answer, while another leaves uncertainty visible. For a work decision, you need to know which claims survive a check.
SuperCompareAI is a Chrome extension for choosing AI services, asking multiple AI models at once, and comparing their answers side by side. The official pages list 12 selectable services: ChatGPT, Claude, Gemini, Perplexity, Google AI Studio, Grok, GenSpark, Qwen, DeepSeek, Copilot, Z.ai, and Kimi. The official pages also describe using existing AI accounts without provider API keys, browser-side operation, local browser history, question templates, custom sites, and file or image attachments. These are product facts, not a verdict about any model's answer.
If you want to compare multiple AI models simultaneously without rebuilding the same prompt in several tabs, SuperCompareAI keeps the repeated dispatch step in one browser workflow while you do the checking.

Use one shared follow-up
The first answer often hides an assumption. Ask ChatGPT, Claude, and Gemini the same second question instead of repairing only the response you liked less:
Prompt example
Review your previous answer. Name one assumption that could fail, one claim I should verify, and one change you would make if the audience were [audience].
Compare the revisions as carefully as the first answers. Did a service notice a real gap? Did it change a recommendation without explaining why? Did it ask for information that the original prompt did not provide?
Do this before you let one answer influence how you read the others. Once you paste one model's response into another, you are testing synthesis rather than the original side-by-side question.
Keep a small test record
The extension sending one question to selected AI services in one browser flow is a product fact. Which answer worked better for your task is a test finding. The first comes from the official product pages. The second depends on your prompt, context, checks, and notes.
Instead of writing "Claude was better" after one run, record what happened. Note the task, the input each service received, the claim you checked, and why one answer was easier to use. That record will be more useful than a single impressive screenshot.
Keep a short comparison note after each run:
• The exact prompt and prompt version
• The services, context, files, and links you supplied
• Claims that still need verification
• The answer or section you used
• What changed after the shared follow-up
• Why the result fits, or does not fit, this task
After a few real tasks, you will have evidence about your own workflow. The result may change with the audience, source material, or type of decision. That is a useful finding, not a failed comparison.
Choose based on the job in front of you
ChatGPT vs Claude with Gemini is a test setup, not a permanent verdict. Keep the conditions visible and choose only after checking the evidence. A different task can produce a different result, even with the same services.
SuperCompareAI can handle the repeated question-and-dispatch step, so you can spend your time comparing evidence and deciding what to use. You still decide what to trust after reviewing the claims and the next action.
