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

What the alternative costsA human proofreader is the alternative; no price is supplied in the available tool data.
If this goes wrong, the tool may change your intended meaning or leave an awkward sentence in place, which you can usually correct before the document is sent.
What to actually do
Do it yourself
The route this page recommends
A chat interface, chat-fluent skill, and roughly 15 minutes until you can act on the result.
How to actually do it
- Open a copy of the document so the original remains unchanged.
- Gather the document's purpose, intended audience, required tone and any workplace style guide or terminology list.
- Paste the prompt into an approved AI tool, then add the purpose, audience and house style in the marked slots.
- Paste the document after the prompt, or provide it through the tool's document upload if that is available.
- Ask the tool to return the corrected version, the change list and sentences needing context, as specified in the prompt.
- Compare each proposed change with the original document, checking that names, figures, dates, technical terms and meaning have not changed.
- Paste the accepted corrections into the working copy, then use your normal document spellcheck and ask a colleague to read any high-stakes or ambiguous passages before sending.
Prompt
Check the document below for grammar, spelling, punctuation, sentence structure and consistency in British English. Preserve the writer's meaning, facts, level of formality and personal voice. Do not rewrite for style unless a sentence is unclear or grammatically incorrect. Do not add information or remove important qualifications. Return: 1) a corrected version, 2) a short list of every substantive change with the original wording and replacement, and 3) any sentence where the correct wording depends on context. Keep names, figures, dates, headings and formatting unchanged unless they contain a clear error. Document purpose and audience: [briefly describe them]. House style requirements: [add any requirements or write none]. Document: [paste the document here]

The distant thirdA person who owns the outcome does this end to end, worth it when the failure is dear.
What it gets wrong
- It cannot know whether an unusual term, name or abbreviation is correct without your context or reference material.
- It may treat deliberate informal phrasing, organisational jargon or a chosen house style as an error.
- It cannot decide reliably whether a grammatically valid sentence says what you intended in a sensitive or ambiguous passage.
- It may alter meaning while presenting the result as a grammar correction, so the original and revised wording still need comparison.
- It cannot take responsibility for the final document or guarantee that every error has been found.
Even on a YES, the friction has a name: context depth and judgement under ambiguity.

FAQ
- Can ChatGPT check my document grammar?
- Yes. Paste the document with instructions to use British English, preserve your meaning and list every substantive change. Check the suggested changes against the original before sending the document.
- Can AI check grammar in a Word document?
- Usually, you can paste the text into a chatbot or use a writing assistant that works with documents and text fields. Keep the original file, then compare the returned corrections with it because formatting, names and specialist terms may not be handled correctly.
- Is AI grammar checking safe for work documents?
- It is suitable for routine text when your organisation permits the use of AI and the document contains no information you are not allowed to share. Remove confidential or personal information where possible, and use an approved workplace tool for restricted material.
- Can AI check British English grammar?
- Yes. Tell it explicitly to use British English and give it any workplace style rules, preferred spellings or terminology. Check words such as organisation, programme and licence against your organisation's own style before accepting the changes.
