QuillReply vs Superhuman
Superhuman is the most admired product in email, and it earns the admiration: a rebuilt, keyboard-driven client that makes fast people faster. It is also a different kind of decision than installing an extension. You move into Superhuman; QuillReply moves into your Gmail.
The short version
Superhuman is a full email client, now part of Grammarly. To deliver its speed and AI features, your mail flows through its systems, and the product replaces the Gmail interface entirely, keyboard shortcuts and all. It costs $25 to $30 per user per month for the entry plan.
QuillReply asks for none of that commitment. Gmail stays exactly as you know it; three buttons appear where your eyes already are. It requests no Gmail API scope, reads only the email on your screen when you click, checks for replies inside your browser, and drafts responses in a voice learned from emails you chose. 30 free actions to try it, then $5 a month.
Side by side
| QuillReply | Superhuman | |
|---|---|---|
| What it is | An extension inside the Gmail you already use | A replacement email client you switch to and learn |
| Access to your mail | None; reads only the open email when you click | Full mailbox, processed through their systems by design |
| Learning curve | None; it is still Gmail | A new interface and keyboard language (that is the point) |
| Follow-up reminders | Yes, including only-if-no-reply, checked in your browser; out-of-office does not count | Yes, built into the client |
| AI drafting | Full replies in a voice learned from your own emails; corrections stick | AI writing and triage built in |
| Email into a task | Apple Reminders, Microsoft To Do, Todoist, Basecamp, with suggested titles and dates | Reminders and snoozes live inside the client |
| Speed features (split inbox, snippets, scheduled send) | No; Gmail's own features remain yours | Yes, the core of the product |
| Price | 30 free actions, one time; then $5 per month, unlimited | $25 per user per month billed annually, $30 month to month (Starter) |
Where Superhuman is stronger
If email is hours of your day and you want the whole experience rebuilt for speed, Superhuman is the best version of that idea: the triage flow, the split inbox, the keyboard-first design, the polish. QuillReply does not compete with any of it, because QuillReply is not a client. People who love Superhuman love the switch itself; if that is you, make it.
Where QuillReply is different
- No switch, no new habits. The two features most people actually cite, follow-up reminders and AI writing, arrive as buttons inside the Gmail you already know. Your muscle memory survives.
- No mailbox in anyone's pipeline. A client has to see everything to work. An extension with no Gmail API scope cannot, in ours or anyone's hands. For client-confidential inboxes, that difference is the whole conversation.
- A fifth of the price. Superhuman's entry plan is $25 per member per month billed annually, which is $300 a year. QuillReply is $5 a month, and reminders land in your real task manager instead of another inbox view.
