Frequently asked questions
Is an AI proofreader always correct?

Does it replace a human editor?
No. It is a writing aid for common corrections and clarity improvements, not a replacement for qualified editing.
Can I copy the corrected result?
Yes. The editor provides copy controls after a successful result.
Which iGrammar tools are available?
iGrammar provides the web editor plus linked mobile, browser, and app options where available. Use the store or extension link for the current platform listing.
Does the app replace the web editor?
No. The web editor is useful for focused reviews and longer drafts, while mobile or browser tools can help when you write elsewhere.
Is my writing automatically published or shared?
No. Review the privacy information for the platform you choose and avoid entering confidential content unless your policy permits it.
