How Hosiqo compares and tests toolsFinal recommendation
Shortlist Felo Subtitles when following and translating multilingual video meetings on zoom, google meet, teams, or webex in real time matters most, and Whisperstream when transcribing imported audio recordings privately on-device matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Whisperstream is a privacy-focused Windows dictation app that turns speech into text entirely on-device, with no cloud upload.
Felo Subtitles, made by Felo Inc. (Sparticle), is a real-time transcription and translation tool delivered as a Chrome/Edge browser extension plus companion desktop apps for Windows and macOS. It listens to meeting and video audio, recognizes speech, and overlays live captions with instant translation into other languages, so participants can follow conversations across language barriers. The browser extension captions web-based audio such as Google Meet (web), YouTube Live, Twitch, and Facebook Live, while the separate Felo desktop app extends coverage to Zoom, Microsoft Teams, Webex, and Tencent Meeting without a bot joining the call. It recognizes speech in roughly 23 languages and translates into about 20 target languages. Captured sessions can be saved as transcripts and exported as text, and the tool offers AI summaries using templates for contexts like sales, learning, and one-on-ones. Custom speech and translation dictionaries let teams add industry terminology. It is aimed at IT, research, HR, legal, education, and video-creator users needing multilingual meeting communication.

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.
