Run a complete proofreading pass on any English text — spelling, grammar, punctuation, style, redundancy, and tone — in one click. Powered by the LanguageTool public API.
Proofreading is the final review pass before publication. While spell and grammar checkers focus on individual issue types, a proofreader runs every rule the engine knows. LanguageTool's combined ruleset includes style, register, tone, redundancy, and clarity — covering far more than typos alone.
Paste your finalised text and click Check. Every available LanguageTool rule fires. The result shows highlighted text with hover tooltips and a numbered list of issues sorted by category — spelling, grammar, style, punctuation. Apply or ignore each suggestion based on context.
Run it as the LAST step before publishing — after writing, after structural editing, after self-review. Catching issues here is much cheaper than republishing or sending corrections later.
Proofread fresh — give yourself an hour between writing and proofing. Read aloud catches issues that silent reading misses. Print on paper for long pieces — your eye behaves differently on screen vs paper.
No — a skilled human catches subtleties (irony, factual errors, audience fit) that no algorithm can. Use this as a first pass; human review for high-stakes content.
Under 5 seconds for typical articles. Longer texts (5,000+ words) may take 10–15 seconds.
No — it only flags issues. You decide which suggestions to accept.
