What is Grammarly?

Grammarly has been around since 2009 and has evolved far beyond spell-checking. The browser extension works across Gmail, Google Docs, Slack, LinkedIn, and practically any text field on the web. The AI suggestions now go beyond grammar to improve clarity, suggest stronger vocabulary, adjust tone, and flag ambiguous phrasing. Grammarly Business adds a company style guide and tone consistency tools. GrammarlyGO (the generative AI feature) can rewrite text, expand bullet points, or change the formality of your writing. For non-native English speakers and professionals who write a lot, it's one of the most genuinely useful tools available.
