The same five prompts from our video, run side by side in Claude, ChatGPT and Gemini. Each tool came out ahead on different rounds, so the best move is to paste the same prompt into all three and keep whichever output fits. We use an example brand, Cool Cotton, an eco clothing label. Run the rounds in order so each one builds on the last, and swap in your own brand details as you go.
Round 1: Product description
Start by giving the assistant the brand so everything after this stays on-brand. Replace the Cool Cotton details with your own.
Write a 450 word product description for my Cool Cotton skirts using the information below:
Cool Cotton focuses on 100% cotton skirts made of organic materials and each purchase contributes to reforestation. Use these details:
product line: clothing, skirts only
audience: eco-conscious people
aesthetic: clean, green and minimal
tone words: friendly, neutral, not very salesyRound 2: Instagram caption
Attach a product image to the chat, then paste this. Each tool writes the caption from what it sees plus the brand you set up in Round 1. In the video we used this one:
Write an Instagram caption for this product image.Round 3: Two-week content calendar
Now plan the launch. The same prompt turns the brand into a ready-to-use posting schedule.
Plan two weeks of content for the brand's Instagram. Make a table telling me the post types, captions, themes, posting cadence for the brand's launch.Round 4: Campaign visual direction
Set the look of the launch so your designer or photographer has a clear brief.
Describe a campaign visual direction involving mood, color palette, styling direction for my brand's launch post.Round 5: Brand-voice customer reply
Finally, use the same brand voice for support. Paste a real customer question and the assistant answers in character.
Give me an answer to this customer's question using the brand voice: "Hello, can I wear this for long use? I plan on going on a long walk and if it gets dirty, I want to be able to keep it in its best condition.
