How to use this generator

1
Paste the full original email
Include the greeting, body, and sign-off. The AI replies more accurately when it can see who's writing, what they're asking, and the relationship cues. Don't trim — context drives quality.
2
Brain-dump your response intent
Don't write polished prose for the intent field — bullet points work great. List every yes, no, question, or condition. The AI handles the prose; you handle the substance.
3
Pick tone for the relationship
A boss email gets 'Professional'. A long-time client gets 'Warm'. A pushy vendor gets 'Firm but Polite'. The same content reads totally different depending on tone — pick deliberately.
4
Read once before sending
AI replies are 95% there but always check for invented details — dates, prices, names. Never send without a 30-second skim. The five-second cost prevents most embarrassing mistakes.

Tips for a great reply

  • Paste the full email — context shapes the reply
  • Use bullets for the intent field; the AI prose-ifies it
  • Match tone to the relationship, not your mood
  • Always read for invented dates or numbers before sending
  • Use 'Short' for follow-ups; 'Detailed' for first replies
  • If they asked 3 questions, make sure all 3 are answered

Common mistakes to avoid

  • Pasting only part of the email and getting a vague reply
  • Forgetting to mention every question that was asked
  • Using 'Friendly' tone for a tense client conflict
  • Sending without re-reading — AI sometimes invents specifics
  • Letting the AI commit you to dates you didn't agree to
  • Picking 'Detailed' when a one-liner would do the job

Frequently asked questions

Will the recipient know I used AI?
Almost never, if you've added genuine intent and edited lightly. AI gives away itself through generic, contentless replies. Yours has your decisions, your dates, your conditions — that's what makes it sound like you wrote it.
Can I use this for sensitive emails?
Yes, with care. For HR, legal, or relationship-critical emails, use the AI to draft a starting point, then heavily personalize. Never paste confidential information that violates your company's data policy or contains client PII.
How do I make the reply sound more like me?
After generating, swap one or two sentences for phrasing you'd actually say. Change 'I appreciate your message' to 'Thanks for the heads-up' if that's how you talk. Two small swaps make a reply feel unmistakably yours.
What if the email is in another language?
Paste the full email in its original language and write the intent in the language you want the reply in. The model handles most major languages well, though sensitive business emails benefit from a native-speaker review.
How do I handle a really long email thread?
Paste the most recent message in full, plus a short summary of the thread context above it. The model doesn't need every reply — just enough to understand the current ask and the relationship history.
Can I save tone presets?
Not yet in this generator. Most users keep a personal note of which tone fits which contact (boss, client, vendor) and reuse the same picks. The selector covers the most common professional tones either way.
