AI Can Write. Content Guardian AgentsSM Make It Right.
AI generates content faster than ever — but human review doesn’t scale, and AI can’t check itself. This creates a serious Content Trust Gap: Is the AI output accurate? On-brand? Compliant? That’s why we built the world’s first Content Guardian AgentsSM. AI can create content — but Markup AI’s Content Guardian Agents perfect your content.
Developer-first by design, our API- and MCP-native solution delivers content guardrails directly into the tools and workflows where your content lives. Instantly, your Content Guardian Agents scan, score, and rewrite any content to enforce your standards for brand voice, terminology, and compliance.
Markup AI gives you the confidence you need to scale your use of AI.

Who we are
Today, content moves faster than review cycles. The risk of brand, legal and revenue damage has never been higher. From increases in financial services compliance issues to airlines paying fines for misrepresentation AI content generation, the signal is clear. There aren’t enough editors and lawyers to catch every issue.
That’s why we created the worlds first Content Guardian Agents. Autonomous AI that lives inside your content workflows to continuously scan, score, and fix content before it ships.
Markup AI is API-first and developer friendly so your teams can build quality gates into your LLM projects through MCP-enabled tools like Cursor, Claude, or your own models. You can wire it into your CMS, delivery platforms, and no-code automations.
We turn your brand style, tone, compliance, and terminology into enforceable rules so writers, developers, and content owners get guidance where they need it.
Markup AI was born out of the incredible research and technology from Acrolinx, bringing forward a new approach to content governance for AI and human generated content.
