CometChat

Real-Time Chat, Voice & Video SDK for Product Teams CometChat is a communication platform that lets developers add real-time chat, voice, and video to any app or website. UI kits, SDKs, and APIs for every major framework, plus no-code embeds for teams that need to move without engineering cycles. Moderation, notifications, analytics, and multi-tenant infrastructure are all built in. AI agents deploy on the same platform, inside the same conversations. CometChat powers 113,000+ apps, handles 7M+ messages per day across 163 countries, with a 7ms API response time and 99.999% uptime SLA. SOC 2, HIPAA, and GDPR compliant. 35+ edge locations. > Who CometChat is for Developers and product teams adding communication to an existing product, not building a standalone messaging app. The typical buyer is a product or engineering lead at a startup, scaleup, or enterprise who needs chat and calls inside their platform and doesn't want to build or maintain the infrastructure themselves. Common team profiles: marketplace product teams connecting buyers and sellers, healthcare platforms enabling patient-provider communication, SaaS companies adding in-app messaging, edtech platforms building live classrooms, community-driven apps that need moderation at scale. > Core Product: Real-Time Conversations 1:1 messaging, group chat (up to 50,000 members per group), and broadcast channels. Voice and video calling (1:1 and group) with screen sharing, recording, and transcription. Rich media support, reactions, threads, typing indicators, read receipts, and 100MB file transfers. Ships with prebuilt UI kits for React, React Native, Flutter, Android, iOS, Angular, and Vue. SDKs and REST APIs for custom implementations. A visual widget builder for no-code embed on any website. All UI components are customizable: branding, layout, and behavior. Integration is fast. Most teams go live with prebuilt UI kits and minimal backend work. The UI kits handle the frontend, the SDKs handle the logic, and the hosted infrastructure handles scale, uptime, and compliance. > AI Agents AI agents run on the same platform as user-to-user conversations: same UI, same moderation, same analytics. Teams can bring their own agent (any LLM, any framework) or build directly in CometChat. RAG and tool-calling support included. The agent UI handles citations, memory, retries, and action buttons out of the box. Use cases: onboarding assistants, support agents, moderation bots, AI-powered triage, conversational commerce agents, tutoring bots. Agents interact inside the same chat threads users are already in, not a separate interface. > Moderation & Safety Content moderation that works across text, images, and multiple languages. Profanity filtering, custom keyword rules, image moderation, user-level controls (block, mute, report), and escalation paths. Rules apply to both user-generated content and AI agent responses. Moderation is on by default: teams configure the rules, not whether moderation exists. Domain-level moderation for regulated industries: healthcare, finance, education, and marketplaces where compliance and user safety are table stakes. > Notifications Push, email, and SMS delivery with per-user preference controls. Quiet hours, frequency capping, retry logic, and custom templates. Notifications respect user timezone and engagement patterns, not just event triggers. Works across all conversation types. > Analytics & Insights Message volume, active users, conversation health, response times, engagement trends, and agent performance in one dashboard. No extra analytics tooling required. Data is available via dashboard and API for teams that pipe metrics into their own systems. > Multi-Tenant Infrastructure Run multiple brands, communities, or customer instances on a single CometChat backend. Isolated moderation rules, branding, and configuration per tenant. Built for SaaS platforms and marketplace operators managing multiple distinct user bases without code duplication. > Developer Experience UI Kits: React, React Native, Flutter, iOS (Swift), Android (Kotlin/Java), Angular, Vue. All customizable. SDKs: JavaScript, Android, iOS, Flutter, React Native. Full chat and calling functionality. APIs: RESTful APIs for server-side operations: user management, message history, moderation actions, conversation creation, and webhook configuration. No-Code: Visual widget builder that generates an embed snippet. Drop it on any website. No framework dependency. Documentation, sample apps, and quickstart guides for every supported platform. Dedicated support for implementation, not just a docs link. > Infrastructure & Compliance Hosted, fully managed infrastructure. 35+ global edge locations. 99.999% uptime SLA. 7ms average API response time. SOC 2 Type II, HIPAA, and GDPR compliant. Data processing addendum available. Scales from early-stage startups to enterprise workloads without infrastructure changes. No self-hosting required. > Industry Use Cases Online Marketplaces - Buyer-seller messaging, transaction-context conversations, fraud detection, and dispute resolution communication. Healthcare & Telehealth - HIPAA-compliant patient-provider messaging, appointment coordination, AI-assisted triage, and secure file exchange. Education & eLearning - Live classrooms, peer-to-peer study chat, instructor Q&A, and AI tutoring, all with age-appropriate moderation. Social & Community - Group chat, public channels, direct messaging, and moderation tooling for communities from thousands to millions of users. Dating - Real-time messaging with scam prevention, conversation prompts, and content moderation tuned for safety. SaaS - Embedded chat and calls inside the product.

Plivo

Plivo is a voice-first AI agent platform designed to streamline multi-channel customer engagement through various communication methods, including phone calls, chat, WhatsApp, SMS, email, and Slack. This innovative solution caters to consumer-facing businesses that aim to enhance their customer interactions by utilizing conversational AI agents. These agents are capable of initiating, answering, assisting, and completing customer conversations, delivering interactions that mimic human-like, natural-sounding dialogue across both voice and messaging channels. The platform is particularly beneficial for businesses looking for efficient customer communications without the need for extensive technical expertise. With Vibe, Plivo’s no-code AI agent builder, users can create and deploy custom voice agents simply by providing straightforward instructions in English. This user-friendly approach eliminates the need for programming skills, making it accessible to a wider range of users, from small businesses to large enterprises. The combination of built-in enterprise-grade telephony, deep partnerships with leading Text-to-Speech (TTS), Speech-to-Text (STT), and Large Language Model (LLM) providers allow companies to design production-ready low-latency (<500ms) voice AI agents at scale, with minimal operational overhead. The seamless integration with popular CRM and support tools further enhances its utility, allowing organisations to leverage existing systems and workflows. This capability is particularly valuable for companies seeking to maintain consistent customer experiences across multiple channels while ensuring that their AI agents can handle a variety of customer inquiries effectively. Plivo’s platform stands out for its vertically integrated Voice AI stack that unifies built-in telephony, speech recognition, synthesis, and reasoning layers in one low-latency system. This integration eliminates the complexity of stitching together multiple vendors, giving enterprises real-time responsiveness, carrier-grade reliability, and full control over voice quality. Combined with Plivo’s no-code Vibe builder and proven CPaaS infrastructure, businesses can move from prototype to production voice agent in minutes, not months. In addition to its AI agent capabilities, Plivo offers an enterprise-grade Communications Platform as a Service (CPaaS) suite. This suite includes essential tools such as SMS API, Voice API, WhatsApp API, Verify API, Number Masking, and SIP Trunking. These features provide enterprises with programmatic control over their voice and messaging infrastructure, enabling them to tailor communication strategies to their specific needs. By combining advanced AI technology with robust communication tools, Plivo equips businesses with the resources necessary to enhance customer engagement and drive operational efficiency.
