Learn LanguageTool Practically
Check spelling, grammar, punctuation and style across languages, configure dictionaries and style rules and paraphrase selected sentences with human editorial judgment.
What You Will Learn
Use LanguageTool to proofread multilingual writing systematically, apply style rules and dictionaries and review paraphrases without losing meaning or voice.
Configure Language and Standards
Select the correct language or dialect, document type, terminology, style guide and approval requirements.
Review Corrections by Category
Separate spelling, grammar, punctuation and style decisions so each suggestion receives context-aware review.
Standardize Team Writing
Use personal or team dictionaries and style guides to protect approved terminology and voice.
Review Responsibly
Inspect factual accuracy, authorship, citations, confidentiality, originality and every accepted change.
1What Is LanguageTool?
An underline is a recommendation, not a command. Professional writers check the selected language and dialect, read the explanation, preserve approved terminology and accept only corrections or rephrases that improve the actual context.
The C–H–E–C–K Method
Use this checklist to turn an idea into a reviewable sequence.
C — Configure Language and Context

E — Evaluate Explanations and Context
Read why a phrase was flagged and decide whether the rule fits the sentence.
C — Customize Dictionary and Style Guide
Add approved names and terms; apply consistent organizational writing rules.

Review rephrases, facts, terminology, meaning and final formatting before approval.

Learn through Controlled Language Experiments
Keep a prompt-and-result log.
Experiment 1: Language and Dialect Test

Check each draft under two language or dialect settings without changing the text.
Compare false positives, missed issues and dialect-appropriate suggestions.
Experiment 2: Suggestion Category Audit
Prepare a paragraph with deliberate spelling, grammar, punctuation and style issues.
Review suggestions by category and read each explanation before deciding.
Classify decisions as accept, reject, modify, add to dictionary or ignore rule.
Experiment 3: Dictionary and Style Guide Test
Create a test set containing brand names, industry terms and phrases that break team rules.
Add approved terms to a dictionary and create one narrow style rule.
Test correct, incorrect, plural, possessive and exception cases before rollout.
Experiment 4: Paraphrase Independence Test
Choose one approved sentence containing a fact, qualification and protected term.
Generate formal, fluent, simple and concise options where available.
Verify whether each option preserved meaning and whether grammar checking caught inherited errors.
