Superhuman alternative if you are leaving over the bundle, not the speed

Not a Replacement Client

Let us clear this up before the comparison table does: Presend will not replace Superhuman. It is not an email client. It has no inbox, no shortcuts, no split view, no snippets, no summaries and no search. If you open it expecting a faster Gmail you will be disappointed within a minute.

Presend is a Chrome extension that sits inside Gmail or Outlook on the web and checks the message you are about to send. That is a different product, and the reason it belongs on this page is that a lot of people who bought Superhuman were not really buying speed. They were buying the feeling of being in control of their email. The bundle has made that feeling expensive, and it turns out the part of email you most need control over — the outbound half — is the part Superhuman never touched.

What Changed in 2025

Grammarly acquired Superhuman in July 2025 and rebranded the combined company under the Superhuman name that autumn. Superhuman Mail stopped being sold on its own. It now comes only on the Business tier, about $33 a month on annual billing or $40 monthly, bundled with Grammarly, Coda and Superhuman Go.

If you were on the old standalone plan, you may be grandfathered. If you are new, you are buying a suite, and if you only wanted the mail client, you are paying for two products you may never open.

Speed Does Not Stop a Bad Send

Superhuman's pitch is that you process email faster. It delivers. But the mistakes that cost the most are not slowness; they are the reply-all with the internal number in it, the pasted key, the "see attached" with nothing attached, the draft that reads like a chatbot because Auto Drafts wrote it. Superhuman speeds all of those up.

Presend sits at the other end. It intercepts the send gesture — click or keystroke — and raises a confirmation when it finds a risk: a credential, an SSN or card pattern, a phrase your company banned, or a rule you wrote at risk severity. Warnings for the softer things sit beside the draft without blocking. You can still send. You cannot send without having looked.

Everywhere, Not Just Email

Superhuman is an email client. Presend runs in Gmail and Outlook Web, guards plain-Enter sends in Slack, checks LinkedIn DMs and posts, X, and every other textarea on the web. The same key that leaks in email leaks in a Slack thread; the same slop that undermines a client email undermines a LinkedIn post, where it escalates to a hard stop because the audience is strangers.

Two Engines Superhuman Does Not Have

Slop. A deterministic catalog of model tells returns clean, traces or slop. It needs no history and works on the first day — which matters if you have been letting Auto Drafts write for you.

Voice. A local engine compares the draft against your own sent messages and returns a verdict — sounds like you, drifts, too short, or not enough of your writing yet — underlining the sentences that drove it. The profile builds from what you actually send, runs in the browser, and never leaves the machine.

Pricing

Superhuman Mail: Business plan, about $33 a month annual or $40 monthly, bundled. Presend: free for twenty-five AI checks a day with local rule checks unlimited, $3 a month for Pro, $29 per user per month for Team. Keep Gmail. Keep the shortcuts you already know. Add the gate.
