Shortlist Amberscript when transcribing interviews, research, and media for accurate records matters most, and Luster when identifying which reps are at risk of underperforming on upcoming deals matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

AI Predictive Enablement platform that pairs realistic sales roleplay with live-call analysis to find and close rep skill gaps.
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.

Luster is a sales enablement platform that describes its approach as Predictive Enablement, combining AI-powered roleplay practice with analysis of real sales conversations. Reps rehearse high-stakes scenarios such as discovery calls and objection handling against AI buyer personas tuned to different sales stages, personas, and deal sizes, and receive feedback designed to surface where they are likely to struggle before those weaknesses show up in live deals. The platform pairs this practice environment with a live-call analysis capability the company calls EchoIQ, which reviews actual customer calls to detect how well reps apply the skills they have been practicing and where execution gaps remain. For managers and enablement leaders, Luster provides predictive insights into skill readiness, prescriptive guidance for onboarding and hiring, certification workflows, and AI-assisted coaching so that practice can be scaled across a go-to-market team. Luster is aimed at sales reps, frontline managers, and enablement teams who want to connect roleplay performance to real revenue outcomes rather than treating training as a one-off event. Pricing varies by plan. Check the official website for current pricing.
