❓Wispr Flow Alternative FAQ
Is there a free Wispr Flow alternative?
Yes. OpenWhispr is free and open source. You can download it from GitHub and use it forever at no cost with fully local, on-device transcription. There's also an optional $8/mo Pro plan that adds unlimited cloud sync, a mobile app, and support, but the core local dictation is free for everyone.
What is the best open-source alternative to Wispr Flow?
OpenWhispr is a leading open-source alternative to Wispr Flow. Wispr Flow is proprietary software, whereas OpenWhispr's entire codebase is public on GitHub (OpenWhispr/openwhispr), so anyone can audit, modify, fork, or self-host it. It uses state-of-the-art Whisper and NVIDIA Parakeet speech models that run locally on your device.
Is Wispr Flow private?
Wispr Flow is a cloud-based service, which means your speech is processed on its servers, and it offers its own privacy controls and policies. OpenWhispr takes a different approach: transcription runs 100% locally on your device by default, so your audio never has to leave your machine. Because data stays on-device, OpenWhispr can help teams meet their own privacy and confidentiality obligations. If you choose to enable optional cloud AI cleanup in Agent mode, you can use your own API keys, but core transcription always stays local.
Does OpenWhispr work offline, unlike Wispr Flow?
Yes. OpenWhispr works fully offline because transcription happens on your device with local Whisper and Parakeet models — no internet connection required. Wispr Flow is cloud-based, so some of its features require an internet connection. If you frequently work on a plane, in a secure environment, or with spotty connectivity, OpenWhispr's offline-first design is a key advantage.
Does OpenWhispr work system-wide in any app like Wispr Flow?
Yes. Both tools work across your applications. OpenWhispr uses a push-to-talk global hotkey that types into any app and any text field system-wide — Slack, email, code editors, documents, and more — on macOS, Windows, and Linux. Wispr Flow also works in any text field but only supports macOS and Windows.
Can OpenWhispr reformat my dictation like Wispr Flow's AI auto-editing?
Yes, via Agent mode. Agent mode reformats raw dictation into structured output using custom system prompts — for example, turning a stream of speech into SOAP notes or a legal brief. The AI cleanup step can optionally use a cloud LLM API if you configure it, while the underlying speech-to-text always runs locally on your device.
