Wispr Flow is a cross-platform AI voice dictation app that turns natural speech into clean, formatted text inside any application on Mac, Windows, iPhone, and Android.
Whisperstream is a downloadable Windows desktop application from Lanreal Technologies Inc. that converts speech to text using push-to-talk dictation. Transcription runs entirely locally on the user's PC via the NVIDIA Parakeet model, so audio is never uploaded to the cloud and no account is tied to the user's voice. It works across any application without add-ins or setup, inserting dictated text directly into tools such as Outlook, Gmail, Slack, VS Code, browsers, and Claude Code. Beyond live dictation, it can import and transcribe existing audio recordings, and it keeps a searchable transcript history with audio replay, encrypted on the device. Additional features include AI cleanup that tidies spoken input, a custom vocabulary for names, jargon, and acronyms, per-app custom AI prompts, support for 25 languages, global keyboard shortcuts, and full offline operation. It requires Windows 10 or 11 (64-bit) with at least 8GB RAM. It targets professionals and privacy-conscious knowledge workers who want fast, local voice input rather than typing.
Best suited for
Wispr Flow is an AI dictation tool that converts spoken words into polished, written text across virtually any app on your device. You activate it with a keyboard shortcut (the Fn key on Mac by default), speak naturally, and it inserts formatted text directly at your cursor, whether you are in Gmail, Slack, Notion, Google Docs, a code editor, or a messaging app. Rather than producing a raw transcript, Flow runs speech through layered AI that removes filler words like "um" and "uh," applies punctuation, corrects spoken backtracking, and adapts tone to the app you are writing in. It supports 100+ languages with automatic detection, plus a personal dictionary for custom terminology and a snippet library for reusable phrases. A Command Mode lets you select text and speak an instruction to rewrite or translate it. It is aimed at writers, developers, professionals, and anyone who wants to draft faster than typing. Note that Flow is a general dictation tool focused on getting text into apps, not a dedicated meeting-recording or call-transcription platform.
