How to use the AI email & letter writer
Type a short description of what you want to write into the box above — for example, "follow up with a client who hasn't responded in a week". Choose the type (Email, Letter, or Message), the tone you want (Professional, Friendly, Formal, Apologetic, or Persuasive), and the length(Short, Medium, or Long), then click Generate.
Not sure what to write? Use one of the quick preset chips — Cover letter, Complaint, Follow-up, Thank-you note, Resignation letter, or Meeting request — to prefill the prompt with a common scenario, then adjust it to fit your situation.
Drafting runs using Chrome's built-in on-device AI, so your prompt is processed locally and never uploaded to a server. If your browser does not support built-in AI yet, you can configure an optional Cloudflare Worker endpoint in the AI Settings panel as a fallback. Once your draft is ready, edit it directly in the output box and use the Copy button to copy it to your clipboard.

Frequently asked questions
Is this AI email writer free to use?
Yes. The AI Email & Letter Writer is completely free with no signup, no account, and no usage limits.
Does my text get uploaded to a server?
No, by default. When Chrome's built-in AI is available, drafting runs entirely on your device and your prompt never leaves your browser. If you configure an optional Cloudflare Worker fallback, text is sent only to that endpoint you control.
What types of writing can I generate?
You can generate emails, formal letters, or short messages. Quick presets are available for common scenarios like cover letters, complaints, follow-ups, thank-you notes, resignation letters, and meeting requests.
Can I change the tone of the generated draft?
Yes. Choose from Professional, Friendly, Formal, Apologetic, or Persuasive tones, and pick a Short, Medium, or Long length before generating.
Can I edit the generated email or letter?
Yes. The output appears in an editable text box, so you can tweak wording, add details, or personalize it before copying.
Why does the tool ask me to enable Chrome built-in AI?
This tool uses Chrome's built-in on-device AI (Gemini Nano) so drafting happens privately without sending your prompt anywhere. If your browser does not support it yet, you can alternatively configure a Cloudflare Worker AI endpoint as a fallback.
What browsers support this AI email writer?
Chrome 128+ with built-in AI enabled works out of the box. Other browsers can use the tool by configuring a Cloudflare Worker AI endpoint in the AI Settings panel.
