Reality Twin vs. Custom GPTs: off ChatGPT, onto your site
A Custom GPT is a fast way to wrap ChatGPT around some instructions and files. Reality Twin is a product: a Twin embedded on your own site, grounded in your live content, that captures leads, books meetings and is discoverable by other companies' Twins.
The short answer
A Custom GPT lives inside ChatGPT, answers from files you upload, and can't capture a lead or book a meeting on your website. Reality Twin embeds on your site, re-crawls your content, scores and stores leads, books appointments and joins a discovery network. For a personal helper, a Custom GPT is great. For a business surface, Reality Twin is built for it.

1 · It's on your site and it converts
A Custom GPT sits behind ChatGPT's login and can't put a lead in your CRM. Reality Twin runs on your own domain, captures the visitor's details, scores intent and notifies your team — a growth tool, not a sandbox.
2 · Fresh knowledge, no re-uploading
Custom GPT files go stale the moment your pricing changes. Reality Twin re-crawls your site on a schedule, so the Twin is always current without you re-uploading anything.
