Zetteldesk is a mail agent plugin for Claude, ChatGPT and Claude Code: your agent writes the letter in the chat and checks the PDF against DIN 5008, and Zetteldesk prints it, puts it in an envelope and takes it to the post office.
Be the first to rate Zetteldesk. Your feedback helps other users decide.
Enter one URL in Claude.ai, ChatGPT or Claude Code and sign in with standard OAuth, so no API keys sit in the chat history.
Before anything costs money, the agent checks the A4 format, address field and page count and gets an exact price quote to show you.
After you confirm, the letter is printed and posted in Germany, with status visible on the web or by asking your agent.
