Question 1

Is iGrammar's grammar checker completely free?

Accepted Answer

Yes. The grammar checker at check.igrammar.app is free to use with no sign-up required. You can paste any text and get instant corrections for grammar, spelling, punctuation, and sentence structure. iGrammar also offers a Chrome extension and iOS app for free, with optional premium features for advanced writing tools like tone adjustment and plagiarism checking.

Question 2

What types of errors does iGrammar's grammar checker fix?

Accepted Answer

iGrammar checks for spelling mistakes, grammatical errors, punctuation issues, incorrect word choice, run-on sentences, and sentence clarity problems. It goes beyond basic spell check by analyzing sentence structure and context, so it catches errors like subject-verb agreement mistakes, misused homophones (their/there/they're), and unnecessary passive voice that a standard spell checker would miss.

Question 3

How do I use iGrammar to check my grammar online?

Accepted Answer

Visit check.igrammar.app and paste or type your text directly into the editor. iGrammar will instantly highlight errors with suggested corrections. Click any underlined word or phrase to see the fix and accept it in one click. No account or download is needed for the web version. For real-time checking as you type across any website, install the iGrammar Chrome extension. Some advanced features may require a premium plan.

Question 4

Can iGrammar paraphrase and rewrite my text?

Accepted Answer

Yes. iGrammar includes a built-in paraphrase tool that rewrites sentences and paragraphs while preserving the original meaning. You can choose from multiple tones — academic, business, casual, or creative — depending on your audience. This makes it useful for students who need to avoid plagiarism, professionals rewriting emails for clarity, and content writers refreshing existing copy.

Question 5

What's the difference between paraphrasing and grammar checking in iGrammar?

Accepted Answer

Grammar checking corrects errors in your existing text — fixing punctuation, spelling, and sentence structure while keeping your original words intact. Paraphrasing rewrites your text entirely, restructuring sentences and replacing words for better clarity or a different tone. In iGrammar's workspace, you can use both tools on the same text: first fix grammar errors, then paraphrase for style — all in one place.

Question 6

How does iGrammar compare to Grammarly?

Accepted Answer

Both tools help with grammar, spelling, and punctuation, but they differ in scope and accessibility. Grammarly offers advanced features like tone detection, style suggestions, and plagiarism checking in its premium plans. iGrammar provides grammar checking, paraphrasing, summarizing, and plagiarism review in one simple workspace — available to use for free with no sign-up required. This makes it a practical, no-cost alternative for students and everyday writers looking for an all-in-one writing assistant.

Question 7

Is iGrammar good for students?

Accepted Answer

Yes, iGrammar is particularly well-suited for students. It checks grammar and punctuation errors in essays and reports, offers an academic paraphrase mode to help rephrase research without plagiarizing, and includes a text summarizer to condense long reading material. The web checker requires no account, so students can use it instantly on any device. The iOS app is also available for mobile writing on the go.

Question 8

Does iGrammar work without creating an account?

Accepted Answer

Yes. The web grammar checker at check.igrammar.app works instantly without any sign-up or login. Just open the page, paste your text, and check. This makes it faster than most grammar tools, which require email registration before letting you use even the basic features. An account is only needed if you want to save your writing history or access premium features.

Question 9

Does iGrammar work with Google Docs and Gmail?

Accepted Answer

Yes. The iGrammar Chrome extension works across Google Docs, Gmail, LinkedIn, and most text fields in your browser, giving you real-time grammar suggestions as you type — without copy-pasting into a separate tool. For longer documents you're drafting in Google Docs, the extension integrates directly into the writing environment so corrections appear inline.

Question 10

Is there an iGrammar app for iPhone?

Accepted Answer

Yes. iGrammar has a dedicated iOS app available on the App Store, designed specifically for iPhone and iPad. Unlike many grammar tools that are desktop-first and adapted for mobile, iGrammar's iOS app is optimized for on-the-go writing — checking emails, social media posts, and messages in real time. It integrates with iOS's keyboard system so corrections work across your favorite apps.

Question 11

Can iGrammar check grammar in professional emails and business writing?

Accepted Answer

Yes, and this is one of iGrammar's strongest use cases. The tool checks for grammatical errors that undermine professional credibility — incorrect subject-verb agreement, punctuation mistakes in complex sentences, misused words — and the paraphrase tool offers a business tone mode to rewrite casual phrasing into more formal language. The Chrome extension applies these corrections directly in Gmail and Outlook in the browser.
