You should use an online spell checker because readers judge a text by its spelling, and the mistakes in your own writing are the ones you are least likely to see. A check catches typos, grammar slips, and punctuation errors before anyone else reads them.
Some people think that spelling no longer matters, or that they spell well enough without help. This article explains why both ideas are risky, what a spell checker catches, and how to check a text with the Spell Checker.
Spelling still matters
Whether you apply for a job, fill in a form, or write an email to someone you want to impress, a misspelled word works against you. When readers find one, they tend to draw one of three conclusions:
- You don't know better. If you show that you cannot spell a word, readers take the rest of your ideas less seriously.
- You don't care. If you did not care about the spelling, why should the reader care about what you wrote?
- You couldn't be bothered. A check is quick. A reader who sees that you skipped it may skip your text.
None of these impressions helps you, whatever the real reason for the mistake was.
Short forms and playful spellings are fine in a chat with friends. The habit becomes a problem when it slips into a job application, a school essay, or an email to a client. Knowing when to switch back to standard spelling is part of writing well.
Why you miss your own mistakes
Many people trust their own eyes to catch every error. But after you have worked on a text for hours, you no longer read what is on the page: you read what you meant to write. Your brain fills in the missing letter and skips over the doubled word.
That is why a mistake you missed on the first read is likely to slip past on the second and the third read too. A spell checker does not get tired, and it does not know what you meant to write, so it reads the text exactly as it is.
Why good spellers need one too
Other people skip the check because they are sure they know how to spell. But nobody knows what they don't know. Many people spell a few words wrong for years without noticing, such as definately for definitely or seperate for separate.
Spelling is also only part of it. Good spellers still make typos when they type fast, mix up words that sound alike, such as its and it's, and forget a comma. A check looks at all of that in one pass.
What an online spell checker catches
The Spell Checker checks your text against dictionaries and grammar rules. Each issue is underlined in the text and listed beside it, by kind:
- Spelling: typos and words that are not spelled that way in the language variant you chose
- Grammar: for example a verb that does not agree with its subject
- Punctuation: for example a missing comma or a doubled mark
- Style: in Picky mode, wordy phrases, repetition, and wording that could be simpler
Every mark comes with an explanation, so you can see why something is flagged and decide whether the fix fits your text. You stay in charge: you pick a fix, or you ignore the suggestion.
The language variant matters more than many people think. Colour is right in British English and wrong in American English. English comes as American, British, Australian, Canadian, New Zealand, or South African English, so pick yours before you check. If you let the app detect the language, detected English is checked as American English.
How to check a text in 5 steps
- Open the Spell Checker and type or paste your text into the text box, or open a document, such as a Word file or a PDF.
- Choose the language and its variant, for example British English.
- Turn on Picky mode if you also want style suggestions.
- Press Check spelling.
- Go through the underlined issues: pick a fix for each one, or ignore a suggestion that is wrong for your text. Then copy the text, or download the corrected document.
The Spell Checker is free to use and needs no account. A document is checked page by page, so you can start correcting page 1 while the next pages are still being read.
If the app flags a name or a special term that is spelled correctly, choose Add to dictionary, and it is not flagged again in this browser. For every option, read how to use the online spell checker.
When rules are not enough
A check by rules is fast and predictable, but it has a blind spot: a real word in the wrong place. Form is a correct word, so rules find it hard to tell that you meant from.
The AI Spell Checker has an AI model read whole sentences, so it also catches mistakes like this, and clumsy wording. It costs more to run, so its free use is limited: keep it for the texts that matter most. Spell checker or AI spell checker compares the two apps.
A check does not replace a final read
A spell checker cannot know whether a name, a date, or a number is the right one. Let the check catch what your eyes miss, then read the text once more yourself before you send it. The proofreading checklist lists what to look at.
Whatever kept you from checking your texts until now, a check costs you little and can save you from a mistake that a reader remembers.
