Show HN: I built an agent that uses email as a file system

https://www.supafax.com/
1•rohanmahen•1h ago
Hey HN,

We're building Supafax an agent that uses email as its memory and config store.

Here's how it works:

- You email yourself to talk to the agent - The agent uses that slice of your outbox as it's inbox and short term memory - It can insert emails into your inbox to store routines, reminders, and rules for itself

Email is such a good primitive because it's essentially an append-only immutable record of all the valuable context about you and your relationships, and agents thrive on this highly structured surface. The tricky bit is users are very reluctant to share that data with companies. So instead of storing your email in a sql or vdb we leverage your inbox to be that storage space and Supafax stores nothing.

Think we're the only AI email assistant not storing your emails :)
