How the spelling pass works.

Drop in essays, emails, reports, or quick notes. The spell pass works on everyday English drafts in the browser.

02

Check spelling with context

The AI scans for typos, misspellings, and confused words like their, there, and they're using the sentence around them.

03

Review the fixes

Copy the cleaned draft and keep the issue list when you want to understand why a spelling correction was suggested.

Questions

What people ask before they run a check.

How accurate is the Spell Checker?
Our spell checker uses the same AI engine as the Grammar Checker, which means it understands context — not just dictionary lookups. It catches typos, misspellings, and commonly confused words like "affect" vs. "effect" based on sentence meaning.
What types of spelling errors does it catch?
Typos (teh → the), misspellings (recieve → receive), homophones (their/there/they're), double letters (accomodation → accommodation), and regional variants (colour vs. color). The AI uses context to pick the right correction.
Does it check grammar too?
Yes — because it uses the same AI engine as our <a href="/grammar-checker">Grammar Checker</a>, it catches both spelling and grammar issues. Each correction comes with an explanation.
Is this different from the Grammar Checker?
Same underlying tool, different focus. This page is optimized for spell checking — finding and fixing misspelled words. The <a href="/grammar-checker">Grammar Checker</a> page emphasizes grammar rules and sentence structure.
Can it check spelling in other languages?
Currently optimized for English (American and British). It handles both dialects. Support for additional languages is planned.
Does it work with technical and medical terms?
The AI knows common technical, medical, and legal terminology. For highly specialized jargon, review suggestions before applying — the AI might flag a legitimate term it hasn't seen.
Is my text stored or shared?
No. Text is sent to our API for processing and discarded immediately. We do not store, log, or share your content.
What is the character limit?
Up to 20,000 characters per check. For longer documents, split into sections and check each one. Free users get 3 checks per day.
Can I check spelling on my phone?
Yes. All tools work in mobile browsers with a responsive layout. Tap any correction to see the explanation.
Is there a Chrome extension?
Yes. Our free Chrome extension includes Grammar Checker, AI Humanizer, AI Detector, Translator, and Word Counter — accessible via right-click on any website.
How does this compare to browser spell check?
Browser spell check uses basic dictionary matching. Our AI understands context — it catches errors like "I went their" that browser spell check misses because "their" is a real word. Plus you get explanations for every fix.
Can I use it for professional documents?
Absolutely. Catch embarrassing typos in client emails, reports, and proposals before sending. Each correction includes an explanation so you can learn from mistakes.
Does it fix typos automatically?
It shows you the corrected text and a detailed list of every issue found with explanations. You review and decide which corrections to keep — nothing is auto-applied.
Is it really free?
Yes. You get 3 free uses per day, and you can start the first task in your browser before creating an account. Paid plans add higher daily capacity and higher word limits.
Can I pay with cryptocurrency?
Yes. We accept USDT, USDC, BTC, ETH, and other cryptocurrencies. Plans start at $9.99/month.
