Check spelling and grammar in your text. Browser-powered spell check with word statistics and common mistake detection.
This free online spell checker uses a local typo list, grammar hints, and your browser's built-in spellcheck support where available. It also shows writing statistics including word count, sentence count, average word length and estimated reading time. No text is sent to any server - everything stays in your browser.
Type or paste your text into the editor above and ZipTools will show common typo highlights below the editor. Your browser may also underline misspelled words in the editor if native spellcheck is enabled. This free online spell checker requires no sign-up, installs no plugins, and processes your text entirely locally without sending it to any server.
A spell checker identifies likely misspellings - catching typos like "recieve" instead of "receive". A grammar checker analyses word-choice and usage issues. This tool combines a local typo detector, browser spellcheck support, and grammar hints for common confusions such as "their/there/they're", "affect/effect", "its/it's", and "fewer/less".
Browser spell checking uses the same dictionary engine as the OS-level dictionary (Hunspell on most platforms), which covers standard English vocabulary well. It accurately flags misspelled common words, but may flag correct technical terms, proper names, abbreviations and domain-specific jargon as errors. The advantage over server-based checkers is complete privacy - your text never leaves your device. For professional publication, browser spell check is a fast first pass, best followed by a human proofread.
The reading time estimate above uses the standard average adult reading speed of approximately 200 words per minute for online content. For a 1,000-word article the estimated reading time is 5 minutes. Research by Contently and Medium suggests average blog readers read at 200-250 words per minute, while technical documentation may be read at 100-150 words per minute due to re-reading and processing time. The statistic panel also shows unique word count, character count, sentence count and average word length.
Yes - this online spell checker processes your text entirely in your browser. Nothing is uploaded to any server, and no text is stored, logged, or transmitted. This makes it safe for checking confidential documents, private emails, internal reports, or any sensitive writing. All statistics and grammar hints are calculated locally using JavaScript, with zero server-side processing.
