Willow Voice is a system-wide AI dictation app for Mac, Windows, and iPhone that converts speech into cleaned-up, formatted text and inserts it at the cursor in any application.
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.

Willow Voice is an AI dictation tool that turns spoken words into polished written text inside any application. Instead of recording meetings, it works at the cursor: you place your cursor in a text field (such as Gmail, Slack, Notion, iMessage, or a code editor), hold a hotkey, speak naturally, and formatted text appears in place. As it transcribes, Willow automatically removes filler words, fixes punctuation, and applies formatting, and it can learn your writing style to adapt tone across different apps. The product is built for professionals who want to write messages, emails, and documents faster than typing. It runs on Mac, Windows, and iPhone, supports voice commands for inserting line breaks and bullet points, handles many languages, and offers an auto-learning dictionary for names and terminology. Willow advertises low-latency transcription and an AI mode that expands brief spoken notes into complete messages. For organizations, it markets SOC 2 and HIPAA compliance, zero data retention, and admin controls. It is a dictation tool rather than a meeting or call recorder.
