Shortlist Clevercast when adding live multilingual closed captions and subtitles to conferences and webinars matters most, and Whisperstream when transcribing imported audio recordings privately on-device matters most. Try them side by side on real calls before deciding — needs vary by team.

Clevercast is a SaaS platform for multilingual live streaming and accessibility, aimed at organizations broadcasting events, conferences, webinars, and meetings to global audiences. Incoming audio and video are sent from an encoder to Clevercast, which generates AI closed captions described as having high accuracy, including for streams where multiple languages are spoken. From that speech-to-text source it can produce live subtitles in multiple languages, synthetic AI voice translations that viewers select per language, and on-site scrolling transcripts displayed on screens for event attendees. A web interface lets operators correct the AI transcription in real time, improving the resulting captions and translations, and remote human interpreters can also be added for events with strict quality requirements. Streams are delivered via HLS through a global CDN and can be embedded in Clevercast's player or distributed to platforms such as YouTube. It suits enterprises, international bodies, educational institutions, and media companies that need accessible, language-inclusive live broadcasts rather than a personal meeting note-taker.

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.
