Overview
LanguageTool checks grammar, spelling and style in many languages. It runs as a browser extension and as add-ins for common word processors, and it offers an API for developers. A free tier exists with limits, and paid plans add extra checks and rewriting features; confirm current limits on the vendor’s pricing page.
Who it’s for
Writers who work in several languages and want one checker across email, documents and the web. See our guide to using an AI writing assistant without losing your voice.
