Shortlist Amberscript when transcribing interviews, research, and media for accurate records matters most, and Trellus when increasing connect rates with a parallel dialer matters most. Try them side by side on real calls before deciding — needs vary by team.
Audio and video to text service offering automatic and human-verified transcripts and subtitles.
Real-time AI sales coaching and parallel dialer delivered as a lightweight Chrome extension that layers onto existing sales tools.
Amberscript is a speech-to-text service that converts audio and video into text and subtitles, offering both automatic AI transcription and human-verified options. Users upload recordings and choose between editable automatic transcripts produced by speech recognition or expert-reviewed transcripts refined by professional editors for higher accuracy. The platform similarly provides subtitles in either automated or professionally edited form, including translation services, and offers a transcript editor for reviewing and correcting output. Amberscript supports a large number of languages and additionally provides a speech-to-text API and data annotation services, as well as a meeting transcription offering for capturing and converting spoken meetings into text. The combination of self-serve automatic transcription and a human-review tier lets users trade off speed against accuracy depending on the use case. Amberscript is aimed at researchers, media organizations, businesses, and public-sector users who need reliable transcripts and subtitles, including those with accuracy or accessibility requirements that justify human-reviewed output rather than automation alone. Pricing varies by plan. Check the official website for current pricing.

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.
