Superhuman makes you a faster typist. Elani makes you a manager.
Superhuman is an incredible tool if your goal is to manually process 100 emails a day as fast as possible. It has great shortcuts and a nice design. But you are still the bottleneck. You are still the one reading, thinking, and typing every character.
Elani doesn't want you to process email faster. She wants you to process lessemail. She reads the thread, understands the context from your calendar and CRM, and drafts the reply for you. You just click "Approve". It's the difference between a faster typewriter and a human assistant.
