AI-based grammar checking can miss context-specific errors or over-correct stylistic choices that were intentional -- review each suggestion rather than accepting all changes blindly, especially for technical or creative writing. Usage may be limited per day depending on login status and subscription tier.Privacy & your data
Your input is sent from your browser to A2Z Tools' own server, which forwards it to OpenAI's ChatGPT API to generate a response. This is server-side / external-AI-provider processing, not browser-only. Some usage requires login, and daily usage counts are tracked for subscription/quota purposes; the generated text itself is not evidently stored separately from that usage count based on this codebase.Frequently asked questions
Will it catch every grammar mistake?
Not necessarily -- AI grammar checking is generally accurate but can miss context-specific issues or occasionally suggest unnecessary changes, so review each suggestion.
Is my input sent to a server?
Yes. Your input is sent to A2Z Tools' own server, which forwards it to OpenAI's ChatGPT API to generate a response -- this is not processed only in your browser.
Is there a usage limit?
Some usage requires login and may be limited per day depending on your subscription tier; unlimited plans may also exist depending on your account.
Is the AI-generated output guaranteed to be accurate?
No. AI-generated content can contain errors or generic phrasing and is not guaranteed to be accurate, original, or plagiarism-free -- always review before using it.
