# ChatGPT can build your ROI calculator inside the answer now. Publish the numbers it can't make up.

OpenAI's GPT-6 rollout on October 7 lets ChatGPT build a small working tool inside the answer, and that puts the ROI calculator on your site in a new race. [OpenAI's GPT-6 post](https://openai.com/index/gpt-6-for-everyone/) calls it Intelligent UI. Answers can carry charts, forms, tappable buttons and tools. Its own examples include a savings calculator and a bill splitter, built on request.

Paid tiers got it first, then Free and Go. OpenAI puts the audience at more than 1.2 billion people a week.

So a generic calculator is now something a buyer can get without visiting you. What the model can't make up is your inputs: your real prices, your plan limits, the numbers your customers actually see. I'd put those on a plain page, in text a crawler can read. Then let the tool get built wherever the buyer already is.

If a buyer asks ChatGPT to compare you with a rival, the answer may come back as a widget. The only question is whose numbers fill it.

The calculator was never the moat. The numbers in it were.
