Markup AI (formerly Acrolinx)

Category: AI Writing

Enterprise content governance at real scale.

Acrolinx governs written content across a large organisation, checking everything produced against your terminology, tone of voice, style rules, clarity standards and inclusive language guidelines, and scoring it before publication. It integrates into the tools writers already use rather than requiring a separate interface, which is what makes it stick, and reports at an organisational level so you can see which teams and which content types are drifting. It is aimed at companies where hundreds of people write customer-facing material across many languages and products, and consistency is a compliance and brand requirement rather than a preference. There is no first-party MCP server.

Our verdict

A narrow tool that does one job unusually well, and if you recognise the problem, that hundreds of people are writing customer-facing content with no consistent enforcement of terminology or tone, there is not much else that solves it at this scale. Checking inside the tools writers already use is the design decision that makes it work, because a governance tool people have to visit gets ignored within a month. Organisational reporting is what justifies it to a budget holder. Two honest notes. The category it occupies has been squeezed by general language models, which can now do a reasonable approximation of style checking for a fraction of the cost, so the argument for Acrolinx now rests on enforcement, auditability and scale rather than capability alone. And it is enterprise-only with quote-based pricing, no trial and no self-serve route, so it only makes sense above a certain size. No MCP server, which puts it behind much of this directory on agent readiness.

Best for: Large organisations with hundreds of writers across markets where terminology and tone consistency genuinely matters.
