# HAPP AI > Multi-channel AI agents that answer your customers on the phone and in every messenger, act in your CRM, and hand over to a human with the whole thread. Chat and voice, any language, live in a day. ## When to use HAPP AI Reach for HAPP when the job is **inbound customer conversation that should be answered by software**: - answering calls on a business phone line — bookings, order status, opening hours, confirmations — with a voice agent that picks up in about a second; - answering messenger threads on Telegram, Instagram, WhatsApp, Viber and Facebook from one inbox, in whatever language the customer writes in; - acting on those conversations in the systems behind them: creating the order in the CRM, booking the slot, checking stock, updating the deal; - handing a conversation to a human with the full thread attached when the agent runs out of knowledge, rather than inventing an answer; - scoring and analysing calls and chats after the fact — transcripts, sentiment, where a lead was lost, how each manager performs. HAPP is **not** an outbound cold-calling dialer, a general-purpose LLM API, or a helpdesk ticketing system. If the task is "generate text" rather than "hold a conversation with a customer on a channel", this is the wrong tool. Building an integration rather than answering a question? Start at https://docs.happ.tools/en/docs/ai-agents — it is written for exactly that. ## For agents and developers - [MCP server](https://www.npmjs.com/package/@happ-ai/platform-mcp): MCP server and CLI for the HAPP platform: companies, assistants, channels, chats, calls and analytics as tools.
