Boostlingo is a language-access company whose product suite spans interpreter scheduling, on-site interpretation, remote video and phone interpretation, on-demand interpreter access, and AI-powered live captioning and translation. Its AI Pro engine provides transcription, live translation, and video captioning for meetings, events, and webinars, and the Boostlingo Events offering delivers continuous AI-translated captions for onsite, hybrid, and virtual sessions. Attendees can access live AI captions through a shared link or QR code without downloading anything, with captions appearing in their selected language in real time, and organizers can set default languages and enable automatic translation so the system streams translated captions throughout a session without manual switching. The platform supports a large number of languages and thousands of language pairs and integrates with major video-conferencing platforms including Zoom, Microsoft Teams, and Webex, as well as in-person and hybrid event setups. Boostlingo continues to expand its AI capabilities, including a more recent AI Interpreter that joins its AI captions and translations features. The product is actively operating in 2025/2026 and is well suited to event organizers, enterprises, and language-service providers that need scalable multilingual captioning and translation across both AI and human interpretation workflows. 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.
