Spell check
Istio.com checks spelling and punctuation online. A free tool for spotting errors and typos.
What errors does the service detect?
Spelling and punctuation checks use LanguageTool. Supported error types and accuracy vary by language. Examples include:
- repetitions or lack of spaces;
- repetition of punctuation: two dots or commas in a row;
- separating introductory words in sentences;
- highlighting errors in concordance;
- grammatical and lexical errors;
- word repetition;
- typos;
- lower case letters at the beginning of a sentence;
- compound words that must be hyphenated.
This screen shows spelling suggestions and character counts. Word frequency and filler metrics are available in the separate text analysis tool.
No registration or authorization is required to use the website.
