## 料金とプラン

Free tier with a one-time $20 signup credit and no credit card. Pay-as-you-go usage pricing: audio from $0.001 per participant minute, 720p video from $0.004, 1080p from $0.009; recording $0.015/recorded min; real-time transcription $0.02/min; post-call transcription $0.004/min; summaries $0.005/request; storage $0.003 per minute per month. Enterprise plans with custom concurrency, SLAs, and private cloud deployment are quoted on request.

## 主な機能と特長

- **Cross-platform real-time audio & video:** Drop-in SDKs for Web, iOS, Android, Flutter, and React Native deliver sub-100ms audio/video with active speaker detection, screen share, chat, polls, Q&A, and a pre-call lobby.
- **AI voice agent framework:** Compose speech-to-text, LLM, and text-to-speech providers into an agent pipeline with VAD and turn detection, then run it server-side on VideoSDK's managed infrastructure.
- **Interactive live streaming:** Ship low-latency interactive streams with audience chat, polls, live captioning, RTMP out, HLS for large audiences, and WHEP/WHIP protocol support.
- **Recording and storage controls:** Record composite or per-participant audio and video tracks with custom layouts and encryption, and send files straight to your own S3, GCP, or Azure bucket.
- **Transcription, captions and AI summary:** Real-time live captioning plus post-call transcripts and prompt-based summaries across 100+ languages, with session metrics, logs, and region analytics for every call.
- **Telephony and observability:** Connect VideoSDK to your phone system via SIP and monitor thousands of parallel sessions with device, region, latency and bitrate dashboards.

## 主なユースケース

- **Telehealth and video consultations (Healthcare and service teams):** Add on-demand or scheduled consultations with recording, live captions, and SIP dial-in to existing patient or client portals.
- **Video KYC and remote onboarding (Fintech product engineers):** Meet identity checks with per-participant recording, session logs, and low-latency video calls that reduce drop-off during onboarding.
- **Voice AI agents and support bots (AI product teams):** Build an always-available voice agent that transcribes, reasons, and responds in real time over calls or browser sessions.
- **Ed-tech classrooms and live events (Education and media companies):** Run classes, webinars, and events with interactive streaming, chat and polls, live captioning, and RTMP restreams to social platforms.

## 強み

- Genuinely transparent per-minute pricing published in detail, including add-ons and concurrency caps
- One vendor covers calls, live streaming, recording, transcription, and AI voice agents
- Broad platform coverage: web, React Native, Flutter, iOS, Android plus server-side SDKs
- $20 free credit and no credit card required lowers the cost of prototyping
- Enterprise options include VPC deployment, custom SLAs, and 99.99% uptime commitments

## 制約・デメリット

- Pricing is usage-based per participant-minute, so costs can be hard to forecast for high-concurrency apps
- AI voice agent orchestration requires assembling your own STT/LLM/TTS pipeline and providers
- Some premium capabilities (private cloud, custom SLAs) are locked behind enterprise sales
