A practical test for LanguageTool

This is a suggested evaluation exercise, not a report of a completed test. Use it to gather your own evidence before choosing a tool.

Product information checked on 20 September 2026. Features and plan availability can change.

Sample task

Create a paragraph with one genuine agreement error, an intentional informal phrase and a proper name. Review suggestions without accepting them in bulk.

What to inspect

Separate corrections from preferences. Check whether the proper name is altered and whether a suggested rewrite changes the intended register.

How to decide

Evaluate precision on the language variant you use. A low number of false corrections can matter more than many highlighted suggestions.
