Frequently Asked Questions
What does the AI Proofreader do?
The AI Proofreader analyzes your text using advanced language models to detect grammar errors, spelling mistakes, punctuation problems, style weaknesses, clarity issues, and consistency errors. It highlights each problem with a clear explanation and a corrected suggestion, letting you apply fixes individually or all at once.
How is the AI Proofreader different from the AI Grammar Checker?
While both tools fix language errors, the AI Proofreader also checks for consistency (e.g., inconsistent hyphenation, mixed tenses across paragraphs) and offers a writing style context (General, Academic, Business, Creative, Technical) so the AI tailors its feedback to your document type.
What categories of issues can the AI Proofreader detect?
The tool checks for six categories: Grammar, Spelling, Punctuation, Style (passive voice, wordiness), Clarity (confusing sentences), and Consistency (mixed capitalisation, hyphenation variants, tense shifts). You can toggle any combination on or off.
What writing styles are supported?
You can choose from five writing styles: General, Academic, Business, Creative, and Technical. Selecting the right style helps the AI apply context-appropriate standards for your document type.
How long can the text be?
You can proofread up to 8,000 characters (roughly 1,200–1,500 words) at a time. For longer documents, split them into sections and proofread each part separately.
How do I apply the suggested corrections?
Each detected issue shows an "Apply Fix" button that replaces just that one error. Click "Apply All Fixes" to accept every suggestion at once. You can also copy the corrected text directly from the preview panel.
Will the AI change the meaning or tone of my text?
No. The AI Proofreader corrects only genuine errors and does not rewrite sentences for tone. Every suggestion targets a specific problem and will not paraphrase or alter your intended meaning.
Is the AI Proofreader suitable for academic submissions?
Yes. Select the Academic writing style to get feedback aligned with formal academic standards. For high-stakes submissions always combine AI proofreading with a manual review and consult your institution's style guide.
Does the tool store or log my text?
No. Your text is sent to the AI model for analysis and discarded immediately after the response is returned. Nothing is stored, logged, or shared.
What is a "consistency" error?
Consistency errors occur when the same concept is expressed in different forms across a document — for example, using "e-mail" in one paragraph and "email" in another, or unexpectedly shifting verb tense mid-paragraph.
Can I use this tool for non-English text?
The AI Proofreader primarily targets English text. The underlying language model may catch obvious errors in other languages but quality will be lower than for English.
Is the AI Proofreader free to use?
Yes. The AI Proofreader is completely free with no sign-up, no subscription, and no usage caps. It runs on Groq's fast inference API to deliver results in seconds.
