otto vs
superhuman.
Superhuman is an email client built for speed. It leans on keyboard shortcuts, AI triage, and split-inbox views to help you get through email fast. The category is the premium email client. It is where you go to read and answer mail quicker than you would anywhere else.
Otto is your chief of staff via text — it watches your calendar and email, decides what matters, and sends three or four messages a day. No app. No dashboards. Just the next move.

how they differ
Superhuman makes email fast. You still read every message and decide what to do, you just do it quicker. If your day is spent in the inbox and you want that time cut down, Superhuman is built for exactly that.
Otto keeps you out of the inbox. It reads your email for you, pulls out the few things that matter, and texts you the next move alongside what your calendar is doing. You do not open a client and you do not clear a queue. You get the signal, not the inbox.
If you want to move through your own inbox faster, use Superhuman. If you would rather someone read it for you and text you what to do about it, use Otto. They sit at different ends of the same problem.
