Example

Input

Draft: "Hey! So we looked into your issue and yeah, it was totally a bug on our end. My bad! We've pushed a fix and it should be working now. Let me know if it's still wonky."
Tone: Formal

Output

{
  "rewritten": "Thank you for bringing this to our attention. After investigating the issue, we confirmed it was caused by a defect in our system. We have deployed a fix, and the functionality should now be restored. Please do not hesitate to contact us if you experience any further difficulties.",
  "changes": [
    { "original_phrase": "Hey!", "new_phrase": "Thank you for bringing this to our attention.", "reason": "Replaced informal greeting with professional acknowledgment" },
    { "original_phrase": "yeah, it was totally a bug on our end", "new_phrase": "we confirmed it was caused by a defect in our system", "reason": "Removed colloquial language, used precise terminology" },
    { "original_phrase": "My bad!", "new_phrase": "(removed)", "reason": "Informal apology replaced with implicit accountability in formal context" },
    { "original_phrase": "still wonky", "new_phrase": "any further difficulties", "reason": "Replaced slang with professional language" }

Frequently asked

Will the rewrite change the meaning of my reply?: No. The tool preserves all factual content — refund amounts, timelines, commitments, and action items. It only changes how the message sounds, not what it says. If any fact would be altered, the tool flags it.
Which tone should I use?: Formal for escalated or enterprise customers. Casual for friendly relationships. Technical for developer audiences. Empathetic for frustrated or upset customers. Concise for follow-ups or busy executives.
Can I rewrite the same draft in multiple tones?: Yes. Each rewrite is a separate execution. Some teams run the same draft through empathetic and formal to pick the best fit.
Does it work for languages other than English?: The model supports multilingual rewrites. Best results for English, Spanish, French, German, Portuguese. The tone taxonomy is culturally grounded in English-language support norms.
What if my draft is already in the right tone?: The tool will still return a polished version and note that minimal changes were needed. You still get the readability comparison and any minor improvements.
