Markup AI: sovereignty score and 8 European alternatives

Markup AI, until recently known as Acrolinx, is a content governance platform. It checks content for brand voice, terminology, quality and readiness for AI search, and describes its agents as "Content Guardian Agents". Marketing and documentation teams use it for consistent language. It integrates with Google Docs, GitHub, AEM Guides and Zapier, and via MCP with AI assistants. It replaces comparable commercial writing and style checkers such as Writer or Grammarly Business.

The privacy policy names Markup AI, Inc. in New York as the controller; the Trust Center page carries the name of Markup AI Europe GmbH, and the Acrolinx trademark belongs to that European entity. The site gives no detail on ownership or exact hosting locations; the Trust Center lists hosting regions in the EU and the US, GDPR, a data processing agreement and subprocessors. According to the vendor, user data is not shared with public models or used to train external AI models.

Why digital sovereignty matters with Markup AI

Markup AI is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Markup AI hosts data in EU, US. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

Markup AI is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Markup AI together with your other vendors and gives a total score, a heatmap and the main risk drivers.
