Cresta is an enterprise customer-experience AI platform that unifies human and AI agents across voice and digital channels. It captures conversations through integrations with major contact-center systems such as Genesys, NICE, Salesforce, Twilio, and Amazon Connect, then analyzes those interactions at scale to surface behavioral insights and deliver real-time guidance. Its Agent Assist listens to live conversations and provides agents with in-the-moment suggestions, knowledge, and next-best actions, while a Knowledge Agent proactively surfaces context-aware answers without manual prompting. Cresta's conversation intelligence analyzes 100% of interactions to identify the behaviors that drive outcomes, and its automated quality management scores conversations across the board so supervisors gain visibility without manual sampling. The platform also offers autonomous AI agents that can resolve customer conversations end to end, plus an Agent Operations Center that gives supervisors real-time visibility and intervention tools across both human and AI-led conversations. Cresta is built for large enterprise contact centers in industries such as financial services, travel and hospitality, telecommunications, insurance, and healthcare that need real-time assistance, coaching, and analytics at scale. Pricing varies by plan. Check the official website for current pricing.

DubTab is a browser extension for Chrome and Edge that translates spoken audio in real time as it plays in a browser tab. Rather than requiring file uploads or exports, it listens to the audio of whatever tab is playing and produces live translated subtitles on screen, optional bilingual (original plus translation) captions, and low-latency AI voice dubbing that speaks the translation aloud. The vendor states audio stays in the tab and only text segments are processed, and that translations appear with roughly half-a-second latency suitable for live content. It supports 50+ languages and offers voice selection and volume-ducking controls. Because it works on any site with audio, supported contexts include YouTube, Twitch, Netflix, Udemy, Coursera and Bilibili, as well as meeting and conferencing tools such as Zoom, Google Meet and Microsoft Teams, where it can show what participants are saying in real time. It is aimed at online learners, livestream and international-content viewers, and remote meeting participants who need on-the-fly interpretation and captioning.
