Show HN: Local Email Client for AI Horseless Carriages

[shahahmed]

The AI Horseless Carriages article spurred a lot of conversation about how we should just be giving users the system prompt box [0], and we were pretty surprised that a bunch of email clients didn’t pop up following this pattern [1].

So we went ahead and created a local [2] email client that you can run that processes your inbox with your own handwritten rules. It lets you label and archive based on natural language rules. You can draft responses with your own drafting prompt, and there’s a “research sender” option that uses web search to get public info on a sender. You can customize any of the prompts to fit your needs. We’d love to hear what you think and PRs/issues are welcome!

How do you prevent someone random from asking your bot to archive all your emails (for example) with a specifically crafted email ?

[splitbrain]

Yeah, and if this can also automatically send mails, we not only have prompt injection but also data exfiltration.

We’d love to hear feedback on this. It’s a proof of concept but I really want to 1) offer agents within an inbox (and integrate to” “dispatch” work to agents running in services like n8n or retool), and 2) offer email inboxes for agents themselves just like coworkers.

Lots of cool stuff to build here, and one day soon expand to the full office suite for ai agents.

Why not just create its own email like usual. Provide a MCP to the inbox?
