Hey HN, I built Prismle because I wanted AI help with my email without giving an app full access to my inbox. You get a personal email address (like yourname.assistant@prismle.com). Forward an email to it with an instruction like "summarize this" or "pull out the action items," and it replies. You can also ask it to create calendar events (it sends back .ics files), set reminders (it emails you at the scheduled time), or draft replies.

Since it's just email, it works with Gmail, Outlook, Apple Mail, or whatever you use. No plugins, no extensions, no OAuth permissions. And because you forward individual emails rather than connecting your inbox, Prismle only ever sees what you explicitly send it.

It also supports conversation threads. You can reply to Prismle's response to ask follow-up questions or refine what it gave you, and it remembers the context.

I'm a solo developer and would love any feedback on the product or the approach.
