The short verdict
Grammarly checks and improves writing across email, documents and browsers, with a proper British English setting and brand-tone controls for teams.
Our Grammarly review
Grammarly is the least disruptive way to add AI to a team: it sits in the browser, Outlook, Word and Google Docs, and quietly fixes grammar, clarity and tone as people type. Set the language to British English and it will catch Americanisms too.
Paid plans add full-sentence rewrites, generative drafting and, for teams, style guides and brand tones so every proposal sounds like the same company.
