Decisions Lab vs. In-House Buyer Simulation: When DIY Is Enough and When It Is Not
You can simulate buyer responses in-house with ChatGPT or an internal LLM workflow. If you need ideas, that is often enough. Ask a model for five reasons a message is strong and five reasons it is weak, and you will usually get useful angles for drafting and debate. A general-purpose model is a good tool for that work when you can still change the message easily.
