Dictation in Superhuman

Voice dictation in Superhuman for email replies, longer emails, and exact wording

Superhuman's Write with Voice drafts an email from a spoken outline, but it paraphrases rather than typing your exact words, and it is mobile-only. SnailText dictates your actual words into Superhuman on Mac and Windows desktop, then cleans them up.

AI dictation in Superhuman, on your device

SnailText is AI dictation: a speech model turns your voice into text, then a second model cleans it up, dropping filler, fixing punctuation, and matching the style your work needs. Both models run on your own machine, so nothing you say in Superhuman is uploaded for transcription. Press the hotkey, speak, and the finished text lands at your cursor.

Does Superhuman have built-in dictation?

Superhuman has a voice feature, Write with Voice, but it is AI drafting, not dictation: you loosely say what the email is about and it generates a polished draft in your tone, so it paraphrases rather than capturing your exact words. It is also mobile-only (desktop is not shipped yet) and English-optimized. There is no verbatim voice-to-text in Superhuman's Mac or Windows compose window. SnailText dictates your actual words into Superhuman on both Mac and Windows desktop, runs the speech model locally, and adds an optional AI cleanup pass so you keep control of the content.

Speech to text in Superhuman: how it works

SnailText does not plug into Superhuman directly. It runs system-wide: a global hotkey (Option+Space (Mac) / Ctrl+Space (Windows), customizable) starts recording, the local speech-to-text engine (Whisper or Parakeet) transcribes what you said, and the text is pasted at your cursor through the system clipboard, the same way it lands when you type. That means it works in every Superhuman field, plus every other app on your Mac or Windows machine, with no extension or integration to set up.

That matters in Superhuman specifically: the Write with Voice feature paraphrases your outline into a draft, so you lose your exact words when the precise phrasing matters. Speech to text removes that bottleneck without changing how you work in Superhuman.

Voice to text in Superhuman: what to dictate

Voice typing in Superhuman is not limited to one box. Press the hotkey anywhere a cursor blinks and your speech becomes text, so the things you would normally type out by hand become things you just say.

· Email replies and longer-form messages
· Careful, exact-wording emails where phrasing matters
· Thinking-out-loud first drafts you then edit
· Replies dictated at your desk without the AI rewriting them

Where typing slows you down in Superhuman

· The Write with Voice feature paraphrases your outline into a draft, so you lose your exact words when the precise phrasing matters.
· That voice feature is mobile-only, so Superhuman on Mac and Windows desktop has no built-in voice at all yet.
· Even fast typists hit long-email fatigue, RSI, or think better out loud, where dictating your real words beats typing.

Example dictations for Superhuman

Exact-wording reply

"To confirm the terms we discussed: the pilot runs for eight weeks, we review at the midpoint, and either side can end it with two weeks notice. Everything else stays as in the current agreement."

Longer email

"Thanks for the thorough writeup. I agree with the first two recommendations and want to push back gently on the third, mostly because the timeline assumes the migration is done, and it is not yet. Can we talk Thursday?"

Quick reply

"Sounds good, Tuesday at ten works on my end. I will send a calendar invite with the dial-in and a short agenda so we keep it tight."

Superhuman voice dictation FAQ

Does Superhuman have voice dictation?

Superhuman has Write with Voice, but it is AI drafting, not dictation: you outline an email out loud and it writes a polished version in your tone, so it paraphrases rather than typing your exact words. It is also mobile-only and English-optimized, so there is no verbatim voice-to-text in the Mac or Windows compose window. SnailText dictates your actual words into Superhuman on both Mac and Windows desktop, running the speech model locally.

Why use SnailText if Superhuman already has Write with Voice?

Because Write with Voice paraphrases and only runs on mobile. SnailText captures your exact words, works on Mac and Windows desktop where Superhuman has no voice yet, runs locally, and adds an optional AI cleanup pass you control. When the precise phrasing of an email matters, verbatim dictation beats an AI-generated draft.

Can I use voice typing in Superhuman?

Yes. SnailText adds voice typing to Superhuman on Mac and Windows. Press the hotkey (Option+Space (Mac) / Ctrl+Space (Windows), customizable), speak, and the text lands at your cursor in any Superhuman field, the same way it works for voice to text in every other app on your machine.

Does the dictation work offline?

Yes. SnailText runs the speech model on your device, so dictation works with no internet connection after the model is downloaded. The optional AI cleanup model runs locally too.

Is my voice uploaded anywhere?

No. Audio is processed in RAM on your machine and discarded the moment the text is ready. Nothing is sent to a server for transcription.

How much does SnailText cost?

The free tier gives you unlimited local speech-to-text with no account. Pro adds larger models and the on-device AI cleanup, $7.49/mo or $89/yr for up to 3 devices.
