Browser-based template and rules tool
This utility does not call a live AI model. It combines predefined templates or text rules in your browser, so treat every result as a first draft and verify it before use. See the AI safety and privacy guide.
Check text against a small browser-based list of common English errors, including selected misspellings, missing apostrophes, repeated spaces, and lowercase sentence starts. This is not a full grammar engine, dictionary, dialect checker, or substitute for proofreading. Review every proposed replacement because context can change what is correct.
