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.
