CometChat
CometChat provides SDKs, APIs, UI kits, and embeds for adding in-app chat, voice/video calling, and AI agents to websites and applications. It includes a free development plan plus paid tiers for production use.
Overview
CometChat is an in-app chat, calling, and AI agent platform for applications and websites. It combines SDKs, APIs, UI kits, and no-code embeds so teams can add real-time user-to-user messaging, voice and video calling, and conversational AI features into existing products.
The site positions CometChat as a modular communication stack that can start with messaging and scale into calling, moderation, notifications, analytics, and multi-tenant workflows. It also highlights support for React and other popular frameworks, along with a free development plan and paid tiers for production use.
Core capabilities
Real-time messaging and calling
Support 1:1 chat, group chat, broadcast chat, and voice/video calls, with rich media, reactions, threads, typing indicators, read receipts, screen sharing, recording, and transcription called out on the site.
Moderation and guardrails
Moderate conversations with rule-based, contextual, and AI-powered options, including keyword and pattern filters, media moderation, multilingual support, and human review workflows.
Notification engine
Send push, email, and SMS alerts with retries, quiet hours, frequency controls, and customizable templates, based on the platform feature pages and pricing tiers.
Analytics and insights
Track conversation health and agent performance with built-in analytics and insights, available as part of the platform’s shared systems.
Multi-tenant infrastructure
Run multiple brands, communities, or customers on one backend with tenant-specific logic, moderation, and branding.
Common use cases
In-app messaging
Add a branded messaging layer to a web or mobile product using SDKs, APIs, or UI kits when you need chat inside an existing workflow rather than a separate chat app.
Voice and video sessions
Support consultations, coaching, or sales conversations with 1:1 or group voice and video, including screen sharing, recording, and transcription where needed.
Conversation safety and moderation
Moderate user-generated content with contextual rules, media checks, and escalation tools for communities that need safer conversations and review workflows.
Multi-tenant customer messaging
Operate more than one brand or customer environment from a shared backend while keeping branding and logic isolated per tenant.
User-facing AI agents
Deploy AI assistants with guardrails, re-engagement, and built-in analytics when the product needs a user-facing agent instead of a standalone bot.
