Native dictation for macOS
Dictate anywhere on macOS. Transcribe locally with Whisper or in the cloud with Deepgram and ElevenLabs, clean up and translate with AI through your own provider, then let it paste itself into whatever you're writing.
Try it
See the whole flow, no install needed
A simulation of the real SapoWhisper flow: recording overlay, transcription, AI improvement, and auto-paste. Pick a mode and run it.
In the real app this starts with your hotkey, a combination or a double press of a modifier. Try it here: press Run, or double-tap ⌥ on your keyboard.

AI improvement
A fast model polishes every transcript with the provider you choose
Each transcript runs through a small, fast model from OpenRouter, OpenAI, Groq, or your own endpoint. Your API key stays in the macOS Keychain.

- Fidelity first
Fixes likely errors, drops filler words and improves readability while staying literal: your words, your order. A fidelity guard restores the original text if the AI drifts.
- Output language
Speak in any language and get the final text in the one you choose. Spanish in, English out, no extra step.
- Prompts & vocabulary
Editable per-project modes for Codex, Claude Code, Slack or issues, plus custom vocabulary and personal context applied to every mode.
Power features
Built around the real dictation workflow
Engines and AI handle the transcript. These are the everyday touches that make SapoWhisper feel like part of your Mac, not a separate tool.
Press, speak, paste
Trigger SapoWhisper from any app with a global hotkey, a key combination or a double-tap of a modifier, and the transcript lands at your cursor via auto-paste.
Tuned for daily mic use
Mic test, input gain controls, sound feedback and auto-ducking that lowers system volume while you talk.
Bilingual by design
Swap the interface and the transcription language between Spanish, English or Auto, and recognise both without restarting.
Yours to keep
Export and import your full configuration as a portable JSON file. Free and open source, no account required.
History
More than one-shot transcription
SapoWhisper keeps working after the paste. Search past transcripts, replay the original audio, pin important entries, and run the same clip through another engine when you want a better result.

That beat there crushes it for me like, I don't know, like a thousand hours in the editing. Really, because the editing, in one day I took like five hours, six hours. And you've done it right now literally in five minutes, ten minutes, and you've done it super well, almost like surpassing the level of what I was doing. So that's perfect.
