Yes. Free Check can be used without creating an account or signing in. The editor’s writing-analysis panels and supporting tools are also available without registration. Individual checks and tools may have text-length limits or cooldowns, and Deep Check may offer an optional app or browser extension for advanced in-editor corrections.
No. Free Check is not powered by Grammarly, and it does not use generative AI to rewrite your text. It is GrammarCheck's own checking experience, built directly into this editor. It is not a redirect to another service and it is not a generic chat prompt. GrammarCheck combines a professional proofreading engine with its own correction workflow, language controls, and writing analysis. Text submitted to Free Check is not sent to Grammarly.
- No generative rewriting: Free Check identifies specific issues and suggests targeted corrections without replacing your passage with newly generated text.
- You remain in control: review corrections individually or apply the available suggestions with Fix Errors.
- Six English variants: American, Australian, British, Canadian, New Zealand, and South African English.
- More than basic spellcheck: review grammar, spelling, punctuation, and contextual usage alongside live writing insights.
Some older third-party comparisons evaluate a previous version of GrammarCheck, and some were published by companies affiliated with competing writing tools. Since then, Free Check’s proofreading engine has been substantially improved, and the editor has added Fix Errors, support for six English variants, and the writing tools described below.
Yes. The editor combines proofreading with tools for understanding, revising, and planning your writing:
- Readability and stats See the reading level, choose a target audience, review difficult passages, estimate reading and speaking times, and listen with read-aloud playback.
- Sentence Flow Use color-coded sentence lengths, a Flow Score, and specific tips that can be reviewed directly in the editor.
- Words Find repeated words and phrases, then review every occurrence in the text.
- Guides, goals, and timers Use social-media and essay length guides, set a custom writing goal, share a completed milestone, or start a stopwatch, countdown, or Pomodoro session.
- Thesaurus and translation Look up definitions, synonyms, and antonyms by meaning, then translate the result into a supported language.
- Title Capitalizer Format titles for AP, APA, AMA, Chicago, Harvard, and MLA styles, or apply standard case conversions.
- AI Detector Get an experimental estimate of AI-style writing signals. The result is not proof of authorship.
This tool is for anyone who writes in English. Students and English learners can correct mistakes without generative rewriting, check essay length, and see whether their writing suits the intended audience. Teachers and tutors can demonstrate readability, sentence variety, and recurring wording. Writers and content creators can review flow, repetition, titles, and common publishing lengths. Professionals can check emails, reports, applications, and proposals before sending them. Editors and proofreaders can use it as an additional revision pass while keeping control of the original text.
