Write the same product's copy for different audiences. Per audience: 1. **Why this person buys this** — one sentence. **It must differ per audience.** 2. **Pick one strength to emphasize**, and say why that one. 3. Headline plus sub-copy. 4. **What not to say to this audience.** Rules: - The product is the same but ***the strength you choose must differ.*** **If every audience gets the same strength, the segmentation is wrong — say so.** - Match vocabulary level to the audience. - **Do not caricature an audience.** Describe what they need, not what they are like.
If every segment gets the same pitch, they were not segments. This requires a distinct strength each and says so when it cannot find one.
ChatGPT best balances accuracy, brevity, and respectful segmentation. Claude is specific but speculative, while Gemini overstates health effects and relies on audience assumptions.
