Vapi and Deepgram handle phone calls. 11Labs ships TTS. Hertz is the first to put an AI participant inside a real-time audio or video room — 1:1, multi-party, or broadcast. Embed in your web app. Done.
Pre-qualify in a scheduled Zoom-like room. AI asks, listens, summarizes, books a follow-up with a human rep.
Video avatar with native accent runs 15-min conversation drills. Tracks words, corrects live, reports to student portal.
Customer screen-shares a bug. AI sees the UI, reads the console, walks them through the fix — or escalates to human with full context.
Patient joins a video room before the clinician. AI collects history, reason for visit, meds, allergies. Hands off to doctor pre-populated.
AI anchor delivers segments, fields audience call-ins, reads superchats, translates live into 5 languages. Recording auto-chaptered.
AI joins Google Meet / Zoom as a participant, not a bot-viewer. Speaks only when addressed. Posts summary, actions, decisions to Slack.
Drop the Hertz SDK into a React, iOS, Android, or Flutter app. Ship an audio or video room with an AI participant in the time it takes to boot a container.
// Drop a voice+video AI into any web app — 6 lines. import { Room, useHertz } from "@hertz/web-parties"; export default function Demo() { const room = useHertz({ agent: "agent_sales_maya", mode: "video", // audio | video | broadcast avatar: "nova_v2", // or null for voice-only tools: ["calendar", "crm", "notes"], }); return <Room room={room} theme="warm" />; }
