Perplexity Prompt for Proofreading a Text
Perplexity AI stands out from standard spell checkers by its ability to understand the overall context of a text before correcting errors. While a simple spell checker only catches isolated mistakes, Perplexity analyzes syntactic consistency, verb tense agreement, complex agreements, and even stylistic awkwardness that traditional tools miss. By crafting a well-structured correction prompt, you transform Perplexity into a professional proofreader capable of handling everything from a quick email to a university thesis. The major advantage lies in its ability to explain each proposed correction, making it a learning tool as well as a correction tool. Whether you are a writer, student, professional, or learner of French as a foreign language, a well-designed prompt lets you obtain an impeccable text while understanding the underlying rules. This page offers a main optimized prompt and three variants tailored to your level of rigor, for effectively correcting any type of French text.

Act as a professional French proofreader-reviser. Correct the following text according to these precise instructions:
- Spelling: correct all lexical and grammatical spelling errors (subject-verb agreement, gender and number agreement, past participles).
- Grammar: correct syntax, punctuation, tense consistency, and structural errors.
- Style: point out repetitions, heaviness, and awkward formulations, proposing smoother alternatives.
- Response format: first present the corrected text in full, then list each correction made in a table with three columns: "Original Error", "Correction", "Rule Applied".
Maintain the author's tone and language register. Do not rephrase sentences unless the syntax is incorrect.

Why this prompt works
This prompt works thanks to role assignment (professional proofreader) which guides the model toward rigorous analysis, combined with explicit categorization of the types of errors to address. The structured table output format forces a systematic analysis of each correction rather than a global rewrite. The instruction to preserve the original tone prevents the model from over-correcting or imposing a style not intended by the author.

Expected Output
You will get your text fully corrected and ready to use, followed by a detailed table listing each identified error with its correction and the corresponding grammatical or spelling rule. This format allows you both to immediately use the corrected text and to understand your recurring errors in order to progress.
Frequently Asked Questions
Can Perplexity proofread a text as well as a professional human proofreader?
Perplexity excels at detecting common spelling, grammar, and syntax errors, with a detection rate comparable to professional proofreaders for standard mistakes. However, it may miss certain stylistic nuances specific to a highly specialized field or cultural subtleties. For high-stakes texts (publication, legal documents), it is recommended to use Perplexity as a first pass for correction and then have it reviewed by a human. Perplexity's advantage is that it explains its corrections, allowing you to validate or reject each change with full knowledge.
What is the maximum text length I can have proofread at once?
Perplexity can process texts of several thousand words in a single query. However, for very long texts (over 3,000 words), it is better to break your text into logical sections (chapters, parts) and submit them separately. This allows the model to maintain maximum attention on each passage and prevents errors at the end of the text from being treated with less precision. Add context about the overall document in your prompt so the corrections remain consistent from one section to the next.
How should I adapt the prompt if my text is in a technical or specialized register?
Add a context line at the beginning of your prompt specifying the field: for example, "The following text is a research article in molecular biology" or "This text is a commercial contract." You can also specify not to correct the domain-specific technical vocabulary to avoid specialized terms being mistakenly flagged as errors. If you use industry jargon, mention it explicitly: "Technical terms specific to business law must be kept as is."

**Astuce** : Ajoutez à la fin : « Classe les erreurs par fréquence (orthographe, grammaire, style) et donne un exemple type pour chaque règle violée. » Cela transforme Perplexity en outil pédagogique, pas juste correcteur. Pour un usage professionnel, précisez le registre (soutenu, courant) et le type de texte (rapport, email, article) avant de coller votre texte : le correcteur adaptera ses choix. Évitez les textes trop longs (moins de 500 mots) pour un résultat précis.
