Superhuman Was Acquired by Grammarly — What It Means for Your Inbox
Yes — if you read that Superhuman was acquired and then got confused when “Superhuman” suddenly showed up as the name of a much bigger company, you’re not misreading the news. Two separate things happened a few months apart, and together they make the situation look more dramatic than it is for your actual inbox.
Here’s what changed, whether the email app still works, and what to do if you want something different.
What changed
Grammarly acquired Superhuman on July 1, 2025. Grammarly bought the AI-powered email client to anchor a broader AI productivity suite, folding fast email into its existing writing and communication tools (TechCrunch, Grammarly’s own announcement). The deal terms weren’t disclosed publicly.
Then on October 29, 2025, Grammarly renamed its parent company “Superhuman.” This is the part that trips people up. The company behind Grammarly rebranded the corporate entity to Superhuman, while the Grammarly writing product kept the Grammarly name (AI Business). So “Superhuman” now refers both to the email app and to the parent company that owns Grammarly, Superhuman, and the rest of the suite.
The Superhuman email app still operates. The acquisition didn’t shut it down — it’s still a paid, fast email client. What changed is who owns it and the story around it, not the fact that you can still send mail from it.
Is Superhuman still a paid app?
Yes. Superhuman remains a subscription email client, not a free tool. The acquisition and rebrand didn’t make it free, and being part of a larger company doesn’t change that it sits at the premium end of email apps. If you were paying before, you’re still paying.
What’s worth watching is direction: now that Superhuman the app lives inside a company built around AI writing and assistance, expect the two products to converge over time. That can be a plus if you want everything in one suite — or a reason to look elsewhere if you’d rather not be locked into one vendor’s roadmap.
What to do if you want something different
If the news made you reconsider where your email lives — or you were never sold on paying a premium subscription just to triage faster — the useful question is what you actually want email software to do. Superhuman’s pitch was speed and keyboard shortcuts. A different pitch is having the inbox handled for you.
Carly is an AI executive assistant that runs over email and text instead of being another app you open. It triages your inbox, labels and files messages, drafts replies in your voice, and sends follow-up sequences — and you direct it the way you’d direct a human assistant, by replying to it. It also manages your calendar, scheduling, contacts, tasks, and daily briefings. Pricing starts at $35/month.
It’s an honest difference in category: Superhuman is a faster client you operate yourself; Carly is an assistant that does the operating. If you want the full comparison of fast inbox apps and assistants, we rounded them up in our guide to the best Superhuman alternatives.

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
