Questions

What students ask before they trust an essay checker.

What does the Essay Checker check for?
Grammar, spelling, punctuation, sentence structure, and common essay-writing errors like tense inconsistency and subject-verb disagreement. Each issue comes with an explanation.
Is this different from the Grammar Checker?
Same AI engine, optimized for essays. The <a href="/grammar-checker">Grammar Checker</a> works with any text. This page is tailored for students checking essays, with essay-specific use cases and tips.
Can I paste my entire essay?
Yes. Up to 20,000 characters per check. For very long essays, check in sections (introduction, body paragraphs, conclusion) for better feedback.
Does it check essay structure?
It focuses on grammar and language errors, not essay structure (thesis, argument flow, paragraph organization). For structure help, try our <a href="/ai-essay-writer">AI Essay Writer</a> for outlines.
Will it make my essay sound better?
It fixes errors but does not restyle. For tone and style improvement, use the <a href="/ai-rewriter">AI Rewriter</a> after checking grammar. For making AI-generated text more natural, use the <a href="/ai-humanizer">Humanizer</a>.
Is it safe for academic use?
Yes — it only corrects your text, not rewrite it. Each correction is shown with an explanation so you learn from errors. Always review and understand corrections before submitting.
Does it catch plagiarism?
No — it checks grammar only. For plagiarism detection, use our <a href="/plagiarism-checker">Plagiarism Checker</a>.
Is my essay stored?
No. Text is processed in real-time and discarded immediately. Your essay is never stored or shared.
Does it work with non-native English?
Yes. Especially useful for ESL students — each correction includes an explanation so you learn the rule, not just the fix.
What types of essays can I check?
Any type: argumentative, narrative, expository, persuasive, research papers, lab reports, personal statements.
Is it free?
Yes. You get 3 free checks per day, and you can start the first task in your browser before creating an account. Paid plans add higher daily capacity.
Can I pay with cryptocurrency?
Yes. USDT, USDC, BTC, ETH accepted. Plans from $9.99/month.
Does it work on mobile?
Yes. Paste your essay on any device.
Is there a Chrome extension?
Yes. Our Chrome extension includes Grammar Checker, AI Humanizer, AI Detector, Translator, and Word Counter.
How does this compare to Grammarly?
Both fix grammar. Coda One is a better fit if you want to start in your browser and keep essay checks alongside 100+ other tools. Grammarly is a better fit if you want an account-linked assistant that follows you across apps.

Coda One's Essay Checker analyzes your text for grammar, spelling, and punctuation errors using AI models that work well on academic drafts. You get a corrected version of the essay along with detailed explanations for each issue found. Works with essays, research papers, personal statements, and other English writing. Start the first check in your browser, then keep going if the workflow fits.
