LanguageTool capabilities

Rephrases selected sentences or passages to be more formal, simpler, or more concise using AI.

Detects and corrects grammar errors, spelling mistakes, punctuation issues, and capitalization problems in written text.

Embeds LanguageTool's grammar and style checking directly into the writing tools teams already use, without requiring a separate app.

Allows users to add custom words — such as brand names, technical terms, or proper nouns — so they are not flagged as errors.

LanguageTool offers a free tier plus paid Premium and Teams plans at varying price points and character limits.

Flags overused phrases, redundant words, and improper word choices to improve writing clarity and tone.

Lets teams define custom writing rules to enforce a consistent brand voice, tone, and terminology across all team members.
