As of 13 August 2026, AI can check your language grammar.
Most people should do this themselves; the prompt is on this page.

What the alternative costsNo price for a human grammar-checking service is provided in the available tool data.
If this goes wrong: AI changes a correct phrase, misses a subtle error or chooses the wrong level of formality, and you can restore the original and ask for an explanation.
What to actually do
Do it yourself
The route this page recommends
A chat interface, no skill needed, and roughly 15 minutes until you can act on the result.
How to actually do it
- Copy the passage into a document and remove passwords, private messages and any personal information that the checker does not need.
- Choose the language and regional variety, such as UK English, and note who will read the text and what tone you want.
- Open a chatbot or QuillBot and paste the full prompt with the passage in the final slot.
- Ask for the corrected text and the change table, then compare every proposed change with your original passage.
- Check disputed explanations in a trusted dictionary or grammar reference for the language, and keep the original wording where the change alters your intended meaning.
- Paste the final version into the place where you will use it and read it aloud once to catch awkward wording that is not strictly a grammar error.
Prompt
Check the grammar of the text below in [LANGUAGE] for [REGION OR VARIETY, such as UK English]. Do not rewrite it for style unless a grammar correction requires it. Return four sections: 1. Corrected text, preserving my meaning and tone. 2. A table with each change, the original wording, the corrected wording and a short explanation in plain English. 3. Any sentence where more than one grammatical version is reasonable, with the alternatives and the difference in meaning or tone. 4. Any phrase you cannot check confidently because the context is missing. Do not invent facts, change names or add information. If the text is already grammatically correct, say so and suggest only optional style changes in a separate list. Text: [PASTE TEXT HERE]

What it gets wrong
- AI cannot reliably infer whether an unusual phrase is an intentional voice, a regional expression or a mistake without context.
- AI can apply a formal textbook rule when natural usage or the situation calls for something different.
- AI may miss errors involving meaning, word choice, politeness or facts rather than grammar.
- AI cannot replace a fluent speaker or teacher when you need to understand a disputed rule in an unfamiliar language.
- A corrected version can still sound unnatural because grammar checking is not the same as judging idiomatic use.
Even on a YES, the friction has a name: judgement under ambiguity and context depth.

FAQ
- Can ChatGPT check my grammar?
- Yes. Paste the text, name the language and regional variety, and ask for both a corrected version and an explanation of each change. Check changes that affect meaning or tone before using the result.
- Can AI check grammar in another language?
- Yes, for many commonly used languages, especially for clear written passages. It is less dependable with slang, dialects, informal speech and sentences where the intended meaning is unclear, so use a fluent speaker or teacher for disputed points.
- Is QuillBot good for checking grammar?
- QuillBot is a purpose-built option that includes grammar checking and paraphrasing. Use its suggestions as edits to inspect, not as proof that every sentence is correct or natural in your intended variety of the language.
- Can AI explain why my grammar is wrong?
- Often, yes. Ask it to show the original wording, the correction and a short rule-based explanation, then check explanations that you do not understand against a grammar reference or tutor.
