Whisperstream is a privacy-focused Windows dictation app that turns speech into text entirely on-device, with no cloud upload.
123 Notetaker AI is an AI meeting notes and transcription app for Microsoft Teams, built by BlueSky Apps. It runs entirely inside the Teams interface and does not depend on Microsoft Copilot, giving teams an independent option for capturing meetings. During a call, participants can open the app from the meeting window to follow AI-powered transcription that appears in real time in the Teams app sidebar. After the meeting ends, 123 Notetaker AI generates a summary and emails the meeting notes, while transcripts and notes are stored in the user's BlueSky account for later reference. Because it is installed from the Microsoft commercial marketplace and operates within Teams rather than as a browser overlay or external bot, it fits organizations that want note-taking contained in their existing Teams workflow. BlueSky Apps offers a family of conferencing add-ons across Teams, Zoom, and Google Meet, and provides a free plan with paid upgrades for additional capacity and features. The app is currently listed and operating in 2025-2026, and is documented in the company's help center and several third-party Teams tool roundups. Pricing varies by plan. Check the official website for current pricing.

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.
