Resonant + Superhuman
You optimized the inbox.
Now optimize the reply.
Superhuman gave you keyboard shortcuts for everything except the part that actually takes time: writing the reply. That's still a typing problem — and typing is still 40 words per minute. Voice is the layer on top.
Resonant transcribes entirely on your Mac. Press a key inside any Superhuman compose window and speak. Clean, punctuated text arrives in the draft. No audio uploaded. No browser extension.

Reply to a founder intro
“thanks for the intro. happy to chat next week. tues or wed works.”
“Thanks for the intro — and congrats on closing the seed, I saw the news this morning. Happy to jump on a call next week to talk through the go-to-market question you mentioned. Tuesday or Wednesday afternoon both work on my side; I'll send a few concrete slots via the booking link below. In the meantime, the one thing I'd suggest thinking about before we talk: who's your first ten named accounts? Not segments — actual companies, with names of humans at each one. That conversation goes much faster if you already have a list.”
Weekly update to the team
“quick update: shipped the billing fix, onboarding rework in progress, blocked on design review for pricing page”
“Quick update for the team. Shipped: the billing fix went out Tuesday and the dashboard numbers we were arguing about are now accurate — credit to Marcus for catching the edge case on prorations. In progress: onboarding rework is about 60% done, expect a staging link by Friday for anyone who wants to poke at it. Blocked: the pricing page redesign is waiting on a design review, and that review has been bouncing for a week — I'll grab time with Priya directly to unstick it. Nothing else on fire.”
Warm intro to a contact
“hey - meet sarah, she runs growth at acme. sarah - this is james, he runs design at beta. you two should talk.”
“Sarah, meet James. James is the design lead at Beta — I've been working with him for about six months and he's the clearest thinker about onboarding flows I've met in years. Sarah runs growth at Acme and is about to tear down their signup flow from scratch; she mentioned she's looking for someone to sanity-check the direction before committing. I think you two would have a genuinely useful thirty-minute call, and I'd love to be out of the thread now so you can move at your own pace. Have fun.”
The insight
Every millisecond —
except the typing.
That's what's left.
Superhuman users already did the hard work. You memorized the shortcuts. You set up split inbox. You live at keyboard commands instead of mouse clicks. Every friction point between you and a processed inbox has already been sanded down — except one.
The reply itself. The part where you actually produce the words. You can triage ten emails in a minute, but if three of them need a real response, you're suddenly spending ten minutes on those three, typing the same way you did ten years ago. The rest of your inbox stack is operating at 2026 speeds and the compose window is stuck at 2005.
Voice is the missing layer. It's the one optimization Superhuman couldn't ship because it requires software that runs outside the inbox. You write the same quality reply in a quarter of the time, and the whole Superhuman workflow finally runs at a consistent speed from open to send.
You're already at the ceiling of keyboard-driven email. The remaining time isn't in navigation or shortcuts — it's in the physical act of typing sentences. That ceiling is the same one every Superhuman user hits, and software alone can't move it.
The bottleneck is your fingers, not your inbox.
Talking is roughly four times faster than typing for most people, and it doesn't tire out the same way. Replies that felt not-worth-it at 40 wpm feel trivial at 200 wpm — so you write them, and the people on the other end notice.
Inbox zero stops being a grind.
Where it fits
Six reply types where
voice pays for itself.
Long thoughtful replies
The emails worth writing are the ones that take ten minutes to type. Voice turns them into two-minute replies without losing the nuance — and without the temptation to write a three-line brush-off instead.
Investor and founder updates
Monthly updates have a specific rhythm: wins, losses, asks, numbers. Speaking it end-to-end is faster than typing and tends to produce a warmer, more honest tone than the template version.
Intro emails
Good intros take real writing — context on each side, why the connection makes sense, a clear handoff. Voice makes you willing to write the good version instead of defaulting to the bare-minimum one.
Replying on mobile at a desk
You know the pattern: laptop open, Superhuman focused, hands on keyboard — but the reply is long enough that you wish you could just talk it out. Now you can, without picking up your phone.
Late-night inbox zero
When you're pushing to the bottom of the queue and the last twelve emails each need a real reply, typing fatigue is the thing that breaks you. Speaking replies is dramatically less tiring.
Follow-ups that actually move deals
The follow-up that includes the three things you remember from the call is the one that closes. Voice makes it easy to include all three, instead of the one you can still type quickly.
Architecture
Local transcription.
Nothing leaves your Mac.
Work email is the most sensitive thing on most people's computers. Deal terms, hiring decisions, customer complaints, investor asks, anything confidential your team is working on — all of it flows through the compose window. Routing that through a third-party audio service is the kind of decision that gets written up later.
Resonant refuses to route it anywhere. Speech-to-text models run natively on your Apple Silicon chip. The moment you stop speaking, text appears in the draft — processed entirely on your hardware, never touched by any server. Superhuman sees the text, and that's it.
This is the architectural gap between Resonant and tools like Wispr Flow or Otter, which stream your audio to their servers for cloud processing. If your email is sensitive enough to belong in Superhuman, your voice is sensitive enough to stay on the device that heard it.
Free. Local. Works in any text field.
