Shortlist Felo Subtitles when following and translating multilingual video meetings on zoom, google meet, teams, or webex in real time matters most, and Trellus when increasing connect rates with a parallel dialer matters most.

Real-time AI sales coaching and parallel dialer delivered as a lightweight Chrome extension that layers onto existing sales tools.
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.

Trellus is a real-time AI sales coaching and dialing tool delivered primarily as a lightweight Chrome extension that layers on top of existing sales engagement platforms such as Salesloft, Outreach, and HubSpot. Its real-time coaching analyzes call audio during live conversations to detect intent and signals and provides adaptive guidance, nudging reps to adjust pacing, listen more, or change approach as the conversation unfolds. Alongside live coaching, Trellus offers a parallel dialer that lets reps dial multiple lines at once to increase connect rates, with automated voicemail drops and number-health monitoring. The platform also includes AI voice agents that can handle inbound qualification or act as practice prospects for rep training, plus call analytics and performance scoring so managers can review conversations after the fact. A sales floor feature supports team collaboration. Because it runs as a browser extension on top of tools reps already use, Trellus is designed to add live guidance and faster dialing without requiring teams to migrate to a separate platform. It is aimed at sales development reps, account executives, and sales leaders focused on outbound calling performance. Pricing varies by plan. Check the official website for current pricing.
