What types of errors does the grammar checker find?

It detects spelling mistakes, grammatical errors (subject-verb agreement, wrong tense, etc.), punctuation issues, and style suggestions like wordiness or informal language.

Is my text sent to a server?

Text is sent to the LanguageTool public API (api.languagetool.org) for analysis. LanguageTool is open-source software and does not store submitted text. No text is sent to Irreva servers.

Which languages are supported?

This tool checks English (US) by default. LanguageTool natively supports 30+ languages but this interface is optimized for English.

How do I apply a suggestion?

Click on any issue in the list to expand it, then click on a suggestion button to replace the mistake with the suggested correction. The text updates automatically.

Is there a word limit?

The free LanguageTool API supports up to about 20,000 characters per request. For longer documents, split them into sections.

What types of errors does it catch?

Grammar errors (subject-verb agreement, tense consistency), spelling mistakes, punctuation errors (missing commas, incorrect apostrophes), and common style issues.

Does it work for languages other than English?

The tool is optimized for English. Results for other languages may be less accurate.
