OpenWhispr

Free open-source dictation that runs speech-to-text on your own machine

System-wide dictation

Press a configurable hotkey and your words are typed into whichever app has focus — chat clients, editors, browsers and terminals alike.

Local or cloud processing

Run on-device models such as Whisper or NVIDIA Parakeet for full privacy, or switch to cloud transcription with your own provider API keys.

AI cleanup and voice commands

Spoken instructions like "clean this up" or "draft an email" let the model restructure and polish the raw transcript before it lands.

Custom vocabulary learning

Names, jargon and technical terms are auto-learned from your corrections so recurring vocabulary stops being misheard.

Strengths & Pros

+Genuinely free and open source under the MIT license, with the code available for inspection.
+On-device models mean dictation can work fully offline with no audio leaving your computer.
+Works across all apps rather than being locked inside one editor or chat window.
+Publishes SOC 2 Type II, ISO 27001, HIPAA and GDPR-oriented credentials, which is rare for a free tool.
