Developer conversation-intelligence API for transcribing and analyzing voice, video, and chat conversations.
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.

Symbl.ai is a conversation-intelligence platform delivered as APIs and SDKs that lets developers transcribe and analyze voice, video, and chat conversations, including meetings and customer calls. Beyond raw transcription, Symbl.ai focuses on extracting structure and meaning from conversations: it can generate speaker-attributed transcripts, summaries, topics, action items, questions, and entities, and it can score calls and monitor sentiment in real time. It supports both real-time streaming over WebSocket for live meetings and processing of recorded audio and video, which makes it suitable for building meeting assistants as well as sales and support analytics tools. The platform is now part of Invoca and continues to operate, targeting enterprises that want to embed real-time AI agents and analytics into their own products rather than buy a finished end-user application. Typical implementations include adding live transcription and summaries to a conferencing tool, scoring and coaching sales calls, and surfacing compliance or quality signals from conversations. Because it is developer-first, using Symbl.ai requires engineering work to integrate its APIs into an existing application or workflow. Pricing varies by plan. Check the official website for current pricing.
