Agree that interfaces are moving in this direction. But humans and agents will always need a way to send/receive messages and notification asynchronously. Email is the most universal channel and we think it is here to stay.

This. I also think e-mail clients are a more natural interface for managing multiple async conversations/tasks with models/agents from different providers.

There's also nothing stopping this product from expanding to other interfaces/modalities like voice or sms.

Congratulations on your launch.
