## About

Markup AI reviews drafts against an organization's configured quality checks in a single call: brand voice drift, unapproved terminology, style-guide violations, hard-to-read sentences, AI-sounding phrasing, unsupported or risky claims, missing sourcing, and AI-search readiness. Users share content in ChatGPT, optionally state what they are trying to achieve, and get back which checks ran, any configuration warnings, and the flagged issues with locations, explanations, and suggested corrections. Teams can also run an explicit, named set of checks with a chosen persona, brand voice profile, style guide, or content profile, and list the checks and configurations available to their organization.

## How to use

1. **Add it in ChatGPT** Open Markup AI in ChatGPT's Plugin directory (button above), select + to add it and sign in if asked.

2. **Use it in a chat** Type @ in the composer and pick Markup AI, or start your message with its name. ChatGPT may also suggest it when it fits what you ask.
