The request 'chat-with-anyone' is ambiguous: it could mean chatting with AI characters for people, or messaging/chat infrastructure for building an app or connecting agents. For a human wanting to chat with anyone, AI Anyone offers chat with 13,000+ AI characters 6, while Getstream provides SDKs for building in-app chat 4 and Twilio provides messaging APIs across SMS, WhatsApp and more 2. For AI agents to talk to each other, AgentDM 8 and Relayger 10 offer messaging over MCP.
A question back: Do you want to chat with AI characters yourself, or build a chat feature or let AI agents message each other?
