LanguageTool on Ubuntu 24.04 LTS

Overview

LanguageTool is an open source proofreading service that checks grammar, style and spelling in more than twenty languages. It runs as a self contained HTTP server exposing a simple REST API: send a block of text and it returns a list of issues with suggested corrections, powered by a large library of linguistic rules together with statistical and machine learning models. Because it runs entirely on your own machine, the text you check never leaves your infrastructure.

It suits writing assistants and editors that need a private grammar backend, content and documentation pipelines that lint prose automatically, and any application that wants proofreading without sending user text to a third party.

Common uses

• A private grammar backend for a writing or editing application
• Automated proofreading of documentation and content in a publishing pipeline
• Multilingual spell and style checking without sending text to a third party
