What the tool analyses
LanguageTool catches grammar, spelling and punctuation with rules for 30+ languages. Yandex Speller adds a large Russian/Ukrainian dictionary. The AI layer finds contextual errors, explains every issue, and generates a corrected version. Errors are colour-coded: spelling, grammar, punctuation, AI-found.
Frequently Asked Questions
Why does spell checking matter for SEO?
Spelling and grammar errors erode user trust and increase bounce rate — both indirect ranking signals. Google's Quality Rater Guidelines mention text quality as a factor in E-E-A-T. Clean copy also improves conversion rates.
Why use multiple engines?
LanguageTool excels at grammar rules. Yandex Speller has a large RU/UK dictionary. The AI catches contextual errors that rule-based systems miss. Combining all three minimises false negatives.
Is it free? Are there limits?
Yes, fully free with no account required. Input limit is 10,000 characters per check. The public LanguageTool API allows ~20 req/min — if you hit it, wait a moment and retry.
How do I apply a correction?
Click the highlighted error in the text preview, or find the error card below. Each card shows up to four suggestion chips. Click a chip to apply it instantly, or use "Apply safe fixes" for all first-choice corrections at once.
How to check text for errors online
- Paste your text into the editor — no signup needed.

Why text errors cost you traffic
Errors are not a direct ranking factor, but they destroy trust. A page full of typos earns fewer links, mentions and return visits — and those are signals that do count.
On commercial pages the cost is higher: an error in a product description or delivery terms directly affects the purchase decision, whatever the ranking.
Punctuation is its own category. A comma in the wrong place changes the meaning of a sentence, and no algorithm will fix that for the author.
