Markup AI provides an API-driven platform that helps organizations scan, score, rewrite, and enforce quality & compliance standards across their written content. It enables users to define brand-voice/style guides, regulatory or legal criteria, and then integrates with content workflows (via APIs, Zapier, MCPs, or direct app integrations) so that any draft or published content can be checked for consistency, tone, accuracy, and compliance. Pieces of content are flagged if they fail to meet defined standards; side-by-side comparisons show what changed, why, and how much improvement was made. Existing content repositories can also be audited; large batches of content can be identified as being outdated, misaligned, or in need of branding or legal updates, and then rewritten en masse. Its goal is to speed up time-to-publish, reduce risk of brand or regulatory missteps, improve confidence in content operations, and make teams more efficient.
