How It Works
- Paste or upload your text. Open the french grammar checker at Rephrasely and paste your French text, or upload a document for batch checking.
- Auto-detect or choose French. The system auto-detects language, but you can manually set “Français” to prioritize French-specific rules like agreement and accents.
- Scan and highlight issues. The checker underlines spelling, grammar, punctuation, and style issues. Click any highlight to see an explanation and suggested corrections.
- Choose a tone and formality level. Toggle options (formal/informal) so suggestions fit tu/vous usage, register, and audience expectations.
- Accept, modify, or reject suggestions. Apply changes one-by-one or accept all. For ambiguous suggestions (poetry, idioms), keep your original wording and review the explanation.
- Export or continue editing. Download corrected text or continue refining with Rephrasely tools like the paraphraser, translator, or AI writer via the Composer.
Examples
Below are 3 typical French before/after pairs to show what the tool fixes and why.
Original: Je suis aller au marché hier soir. (Transliteration: Zhuh swee al-ay oh mar-shay eerr see-wahr.)
Corrected: Je suis allé au marché hier soir. (Transliteration: Zhuh swee ah-lay oh mar-shay eerr see-wahr.)
Why: Past participle agreement with auxiliary être requires masculine singular "allé". The checker fixes gender/number agreement and suggests accents.
Original: Elle a manger la tarte? (Transliteration: El ah man-zhay lah tart?)
Corrected: Elle a mangé la tarte ? (Transliteration: El ah man-zhay lah tart?)
Why: Correct past participle "mangé" with acute accent and non-breaking space before the question mark in French typography.
Original: Tu veux que je le fais? (Transliteration: Too vuh kuh zhuh luh feh?)
Corrected: Tu veux que je le fasse ? (Transliteration: Too vuh kuh zhuh luh fahs?)
Why: Subjonctif required after "vouloir que"; verb form corrected to "fasse" and spacing before punctuation adjusted.

Tips — French-specific Best Practices
- Mind accents: many French homographs change meaning with accents (ex: "ou" vs "où"). Use the checker to spot missing diacritics and review suggestions before accepting.
- Watch past participle agreement: when using être (arriver, partir) or direct object preceding the verb with avoir, ensure agreement in gender and number.
- Set the right formality level: select formal mode for business letters to adjust vous/tu and suggest polite phrases (e.g., "Je vous prie d’agréer...").
- Check punctuation spacing: French typography often requires a non-breaking space before ; : ? ! and around « guillemets ». Use the tool to enforce correct spacing automatically.
- Be cautious with idioms and regional variants: automated suggestions can misread idiomatic or Québécois forms. Keep original phrasing when the meaning is intentional.
- Use the translator or paraphraser for alternatives: if a suggestion changes tone, try the paraphraser or Composer to generate multiple phrasing options that match your intent.
- For academic or published work, run the /plagiarism-checker after edits to confirm originality and the /ai-detector if you need to validate human vs AI authorship.
