iGrammar Frequently Asked Questions
Can AI help me fix grammar mistakes?
Yes. iGrammar’s AI Grammar Checker identifies grammar, spelling, punctuation, word-choice, and sentence-structure issues. It provides clear corrections to help make your writing accurate, natural, and easy to understand.

Can iGrammar correct all my writing mistakes in one tap?
Yes. With iGrammar’s One-Tap Correction feature, you can identify and correct grammar, spelling, punctuation, and sentence errors instantly. Instead of fixing each mistake individually, you can apply the suggested corrections with a single tap.

Can I use One-Tap Correction while typing in other apps?
Yes. The iGrammar Keyboard helps you check and correct your writing while using supported messaging, email, workplace, and social media apps. One-Tap Correction makes it easier to fix multiple mistakes without editing every word manually.

How can I improve my English writing?
iGrammar provides instant feedback and several AI writing tools. You can use the Grammar Checker to correct mistakes, Improve Text to strengthen your writing, the Paraphrasing Tool to rewrite unclear sentences, and the Tone Changer to match your message to the right audience.

Is iGrammar helpful for non-native English speakers?
Yes. iGrammar helps English learners correct grammar, improve sentence structure, replace unnatural phrases, and find clearer ways to express their ideas. Translation, paraphrasing, tone adjustment, and grammar correction can make English communication easier and more confident.

Is iGrammar useful for native English speakers?
Yes. Native English speakers can also make typos, miss punctuation errors, repeat words, or write unclear sentences. iGrammar helps polish emails, reports, assignments, social media posts, and everyday messages.

Can iGrammar check grammar, spelling, and punctuation?
Yes. iGrammar checks your text for grammar errors, misspelled words, punctuation problems, confusing word choices, and sentence-structure issues. You can review the suggestions or use One-Tap Correction to apply the improvements quickly.

Can iGrammar proofread my writing?
