Claude Prompt for Proofreading a Text

Proofreading text is one of Claude's most powerful uses. Whether you are a writer, student, professional, or content creator, spelling, grammar, and syntax errors can undermine the credibility of your writing. Claude excels at identifying and correcting these errors thanks to its deep understanding of the French language, including complex agreements, irregular conjugations, and typographic subtleties. Unlike a simple autocorrect tool, Claude understands the context of each sentence, allowing it to detect errors that standard tools miss: false cognates, anglicisms, awkward repetitions, or register inconsistencies. By using a well-structured prompt, you get not only a corrected text but also explanations for each modification, helping you improve your language skills. This approach transforms correction into continuous learning, tailored to your level and specific needs.

Why this prompt works

This prompt works because it assigns Claude a precise expert role and breaks down the task into distinct categories (spelling, grammar, style, punctuation), structuring its analysis. The imposed output format with a summary table forces Claude to justify each change, increasing accuracy and reducing overcorrections. The explicit instruction to preserve tone and meaning prevents Claude from rewriting the text according to its own stylistic preferences.

Frequently Asked Questions

Can Claude proofread long texts without any drop in quality?

Claude handles texts up to several thousand words very well. For very long documents (over 10,000 words), it's best to break the text into logical sections (chapters, parts) and submit them separately. This allows Claude to maintain consistent attention on each passage and avoid omissions towards the end of the text. Specify the general context of the document at the start of each section to maintain coherence.

How can I stop Claude from rewriting my text instead of just correcting it?

The key is to be explicit in your prompt. Use instructions like "Do not change the meaning or tone" and "Preserve the author's style." Ask Claude to clearly separate mandatory corrections (spelling, grammar) from optional stylistic suggestions. If Claude rewrites too much, add: "Limit yourself to objective errors. Only suggest rephrasing if the sentence is grammatically incorrect or ambiguous."

Does Claude correct French typography (non-breaking spaces, quotation marks)?

Yes, provided you ask for it explicitly. Claude knows the rules of French typography: non-breaking spaces before double punctuation marks (; : ! ?), French quotation marks (« »), accented capitals (É, À, Ç), and em dashes for dialogue. Mention "French typography" in your prompt to enable this check. Note that the rendering of non-breaking spaces then depends on your publishing tool.
