Markup AI offers an API-based platform designed to assist organizations in scanning, evaluating, rewriting, and enforcing quality and compliance criteria for their written materials. This platform allows users to establish guidelines for brand voice and style, as well as regulatory or legal requirements, integrating seamlessly with various content workflows through APIs, Zapier, MCPs, or direct application connections. As a result, any draft or published content can be reviewed for uniformity, tone, precision, and compliance. When content fails to meet set standards, it is flagged for review, and users can see side-by-side comparisons that illustrate what changes were made, the reasons behind them, and the extent of improvements achieved. Additionally, existing content libraries can undergo audits, enabling the identification of large volumes of content that may be outdated, misaligned, or requiring branding and legal revisions, which can then be rewritten in bulk. The platform aims to accelerate the publishing timeline, mitigate risks related to brand or regulatory errors, enhance trust in content operations, and increase team productivity. Overall, Markup AI streamlines the content management process, making it easier for organizations to maintain high standards across all written communications.
