AI dictation in Substack, 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 Substack is uploaded for transcription. Press the hotkey, speak, and the finished text lands at your cursor.

Does Substack have built-in dictation?

Substack has no built-in dictation in the post editor. It does have voice features, but they point the other way: a voiceover you record for readers, and an AI read-aloud that narrates your published post. Both produce audio for your audience, neither types your draft for you. To speak a post into the editor you need a system-wide tool. SnailText injects text at the OS level, so it works in the Substack editor, the title, and Notes on Mac and Windows, with a local AI cleanup pass.

Speech to text in Substack: how it works

SnailText does not plug into Substack 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 Substack field, plus every other app on your Mac or Windows machine, with no extension or integration to set up.

That matters in Substack specifically: a full newsletter post is sustained writing, exactly where speaking is several times faster than typing. Speech to text removes that bottleneck without changing how you work in Substack.

Voice to text in Substack: what to dictate

Voice typing in Substack 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.

Where typing slows you down in Substack

· A full newsletter post is sustained writing, exactly where speaking is several times faster than typing.
· Substack has no native dictation in the editor, so without a system-wide tool the whole draft is keyboard-only.
· The first draft is where momentum matters most, and stopping to type breaks the flow of a thought.

Example dictations for Substack

Post draft

"This week I want to talk about a small change that made a big difference: moving the transcription onto the device instead of the cloud. It sounds like a technical detail, but it changed how I actually use dictation day to day."

Headline

"Why I stopped sending my voice to the cloud, and what I use instead."

Note

"Quick note between issues: the next post is about the speed-versus-privacy trade-off in dictation apps, and why I think most people have it backwards."

Substack voice dictation FAQ

Does Substack have built-in voice-to-text?

No. Substack has no native dictation in the post editor. Its voice features are a voiceover you record for readers and an AI read-aloud that narrates your post, both of which produce audio rather than typing your draft. SnailText adds dictation to the Substack editor, title, and Notes by inserting text at the OS level on Mac and Windows.

Can I draft a whole newsletter by voice?

Yes. Open the Substack editor, press the hotkey, and talk through your draft. The text lands at your cursor with filler dropped and punctuation fixed, so you get a readable first draft to edit rather than a raw transcript. Long posts are exactly where dictation saves the most time.

Can I use voice typing in Substack?

Yes. SnailText adds voice typing to Substack on Mac and Windows. Press the hotkey (Option+Space (Mac) / Ctrl+Space (Windows), customizable), speak, and the text lands at your cursor in any Substack 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.
