Writing quality across every app, now £10 a month.
Grammarly checks and improves writing wherever you type, across the browser, desktop applications, email clients and documents, covering grammar, clarity, tone, conciseness and consistency with a brand style guide. For teams it adds uploaded style guides, brand tones, knowledge sharing and analytics on writing quality across an organisation, plus agentic features. Two things have changed that most listings have not caught up with. The standalone Business tier is gone: the business page now sells Free, Pro and Enterprise only, with Enterprise routed through a bundle alongside other products. And the parent company renamed itself Superhuman in late 2025, though the Grammarly product keeps its name. It bills natively in pounds, which is unusual here. There is no MCP server, only a REST API covering analytics, licensing and detection.
The distribution is the moat and the reason it survived a wave of general language models that should have killed it: Grammarly is already in the browser, the email client and the document, so it improves writing at the moment of writing rather than requiring a trip to another tab. For an organisation, the style guide and brand tone features are what make output consistent across people who will never read a brand guidelines document. It bills natively in pounds, which almost nothing else in this directory does. Two corrections worth noting. The Business tier no longer exists, so if your notes or budget reference a per-seat business price, that is out of date, and enterprise pricing is now opaque and bundled. The parent rebrand to Superhuman also means company news appears under a different name. There is no MCP server, only a REST API, so it is not addressable from an assistant.
Best for: Teams who want consistent writing quality across everyone's output without anyone having to open a separate tool.
Pricing: Free, then £10/mo (Freemium)
