AgentChat Hub — Chat with Any AI Agent, Instantly. Your AI agents deserve a great interface. AgentChat Hub is the universal messenger for the open AI web — connect to any A2A-compatible agent, any cloud LLM provider, or a model running on your own machine, stream responses in real time, and own every conversation. CONNECT TO ANY AI, THREE WAYS No subscriptions. No gatekeeping. No lock-in. • Bring your own agent — any AI agent built on the open A2A protocol. Host it on Railway, Render, Fly.io, or your own server, then connect with a single URL • Bring your own key — connect directly to Claude, OpenAI, xAI Grok, Moonshot Kimi, or DeepSeek. Your key lives in your device's Keychain and is never sent anywhere but that provider • Run it locally — point AgentChat Hub at Ollama or LM Studio on your own network; the app discovers exactly which models you have installed Test Connection validates your key and model together before you save an agent. GIVE YOUR AGENTS REAL TOOLS Connect any agent to MCP (Model Context Protocol) servers — add a server once, attach it to whichever agents need it, and get real function-calling against those tools, OAuth included. HAND OFF WORK, NOT JUST MESSAGES Give an agent a task with a title and a goal, and it runs its own multi-turn conversation until the job is actually done — no babysitting, no re-typing continue. FEATURES • Universal Agent Client — A2A, Cloud AI (BYOK), and Local Server, all in one app • Live Streaming — watch responses appear as your agent thinks • MCP tool support — real function-calling for any attached agent • Tasks — assign a goal, get back a finished result • Groups & Custom Tabs — organise agents into Work, Creative, Research, or anything else • Rich Attachments — photos, images, and files in chat • Files view — every attachment from a conversation collected in one place • Multi-Agent — add and switch between multiple agents seamlessly • Rename Agents & Custom Profile Photos • Copy & Share — long-press any message to copy or share to Gmail, Messages, Notes, and more • Full iPhone/iPad feature parity — Home, Tasks, Groups, and per-agent detail, everywhere • No Account Needed — anonymous sessions, stored securely on-device • Dark Mode — looks great day or night BUILT FOR BUILDERS The missing front-end for the open AI ecosystem — support bots, productivity assistants, creative writing agents, or local models all get a home here. Built for developers testing A2A agents, teams running internal AI assistants, self-hosters, and anyone who wants a private, clean chat UI. YOUR DATA STAYS YOURS No account. No tracking. No cloud sync. Conversations live on your device and nowhere else. API keys and MCP tokens live in the Keychain. Sessions use a secure anonymous ID — never linked to your identity. OPEN PROTOCOL. ENDLESS POSSIBILITIES. A2A is an open standard for AI agent communication, and MCP is the open standard for giving agents tools. AgentChat Hub speaks both natively. RESPONSIBLE USE AgentChat Hub connects to agents and providers you choose and control. The developer does not operate, monitor, or control any agent, provider, or server you connect to.
