AI Email Writer

Generate professional, friendly, or formal emails in seconds. Powered by DeepSeek AI with your own API key.

How to Use the AI Email Writer

Enter your DeepSeek API key once (stored locally in your browser), describe what the email should say, pick a tone — professional, friendly, formal or concise — and a length, then click “Write Email”. The draft appears ready to copy.

Best for routine messages: follow-ups, meeting requests, apologies, or outreach. Be specific in the topic box — include names, dates and key points — because the clearer your description, the less you will have to edit. Always review names and numbers before sending.

The API key is stored only in your browser's local storage and is never sent to any server other than the DeepSeek endpoint you configured. If you prefer not to enter a key each session, keep the Save Settings toggle on, but remember to log out on shared computers.

Keep the tone consistent with the relationship - use formal for first contact with clients, friendly for colleagues you know well. For longer emails, split the topic into two or three sentences so the writer can structure paragraphs naturally instead of producing one dense block.
