When to use AI Email Writer

You've been sitting on a difficult reply for three days because every draft you write sounds either too aggressive or too much like a pushover. Describe the situation — who it's to, what happened, what outcome you want — pick the tone, and get a complete draft back with a subject line, greeting, body, and sign-off. Assertive for the follow-up that's been ignored for two weeks. Apologetic when you actually are sorry but don't want it to read like groveling. Formal for anything HR-adjacent. The language model runs locally in your browser tab, so client names, salary figures, legal details, and anything else sensitive never reach a server. Copy the draft into your email client, adjust the two sentences that don't sound like you, and send it.

  • Write a firm but polite follow-up after a week of silence
  • Draft a rejection email that keeps the relationship warm
  • Reply to a passive-aggressive thread without matching the energy

About this tool

Drafting a sensitive email is harder than it looks — cold outreach that doesn't sound desperate, a "no" that doesn't burn a bridge, a follow-up that arrives confident without being pushy. Describe the situation, pick a tone, and get a full draft in seconds: subject line, greeting, body, sign-off. Your email content never leaves this browser tab, so client names, salary figures, and anything else you'd rather keep private never touch a server. Edit the draft inline, regenerate with a different tone, or paste it straight into your email client.

Tips

  • Include specific details about the situation — the more context you give, the better the email draft.
  • For replies, paste the original email so the AI can reference specific points.
  • Use "Assertive" for follow-ups and "Apologetic" for sensitive situations.
  • Always personalize the AI draft with your own details before sending.

Frequently asked

Can AI write a reply to an email I received?
Yes. Paste the email you received, describe the tone you want, and the AI will draft a reply. Your email content stays entirely on your device.
What tones are available?
Professional, friendly, formal, apologetic, and assertive. Choose the tone that fits your situation.
Is this AI email writer private? Does it send my emails to a server?
Completely private. The draft is generated by a local model loaded into this browser tab — your email text, recipient names, and any sensitive context are processed on your machine and never forwarded to OpenAI, Anthropic, or any external API.
