Dictation in Slack
Voice dictation in Slack for thread replies, standup updates, and DMs
The Slack desktop app has no built-in voice typing, and most dictation extensions cannot reach it because it is an Electron app. SnailText injects text at the OS level, so it works in any Slack message box, thread, or DM.

AI dictation in Slack, 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 Slack is uploaded for transcription. Press the hotkey, speak, and the finished text lands at your cursor.
Does Slack have built-in dictation?
The Slack desktop app has no built-in voice-to-text in the message box. The mic button records an audio clip (a voice memo); Slack may attach a transcript to that clip afterwards, but there is no dictation that types your words straight into the message field. And because the desktop app is Electron rather than a browser tab, most dictation extensions cannot reach it either. SnailText injects text at the OS level, so it works in any Slack message box, thread, or DM.
Speech to text in Slack: how it works
SnailText does not plug into Slack 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 Slack field, plus every other app on your Mac or Windows machine, with no extension or integration to set up.
That matters in Slack specifically: composing a thoughtful, multi-sentence reply is slow when you would rather just say it. Speech to text removes that bottleneck without changing how you work in Slack.
Voice to text in Slack: what to dictate
Voice typing in Slack 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.
- · Thread replies and longer responses to teammates
- · Status updates, standup notes, and async check-ins
- · Direct messages and quick follow-ups
- · Channel posts and announcements
Where typing slows you down in Slack
- · Composing a thoughtful, multi-sentence reply is slow when you would rather just say it.
- · Async updates like standups and project status are full paragraphs you retype daily.
- · Context-switching all day means lots of short bursts of typing that add up across channels and DMs.
