Navigation speed vs writing speed
Superhuman optimises the motion through your inbox: shortcuts for everything, instant search, a snappy UI, and AI assists bolted on. The win is measured in how quickly you can triage and move on. If you process hundreds of messages a day and the friction is in the handling, that's a real, daily payoff.
echo optimises a different stretch of the same task: the blank compose window. Instead of making you faster at reaching the reply, it writes the first draft of the reply itself, in your voice, so the slowest step becomes a quick edit. The two aren't competing for the same second — they speed up different parts of email.
A new client vs your existing Gmail
Superhuman is a client you switch to; it becomes the place you do email, which is part of the point and part of the commitment. You're adopting a new app, new habits, and a subscription, in exchange for a faster surface.
echo sits on top of the Gmail you already have. You connect one account, it learns from your sent mail, and it drafts replies you review and send from your normal setup. There's less to adopt — you keep your inbox and add an assistant that handles the writing.
Generic AI assists vs a learned voice
Most AI writing features, including those in fast clients, generate from a generic model. They'll produce a competent, neutral reply, but it won't carry your tone, and you'll often rewrite it enough that the time saved shrinks.
echo's drafts are built from your own sent mail, so they aim to match how you actually write — phrasings, length, sign-off and all. That's the difference between 'a reply got generated' and 'a reply I'd plausibly have sent got generated', and it's where echo spends its effort.

- Not exactly — they fix different bottlenecks. Superhuman makes you faster at moving through your inbox; echo makes you faster at writing replies. You can keep your client and add echo for the drafting.
- Do I have to change email clients to use echo?
- No. echo connects to your existing Gmail account and drafts replies there, so you keep your current inbox and habits.
- Does echo have keyboard shortcuts like Superhuman?
- echo isn't a full client built around navigation shortcuts — it's an assistant focused on drafting replies in your voice. The speed comes from not writing from scratch, not from inbox keystrokes.
- Is echo cheaper than Superhuman?
- echo is free in early access, while Superhuman is a paid monthly subscription. Pricing for echo may change after early access.
