Chat with Every Model, Natively
UChat AI is a 100% native AI chat app for Mac, iPhone and iPad. Connect OpenAI, Anthropic, Gemini, Grok and more with your own API key — or run local models entirely offline.
Every Model. One Native App.
Bring your own keys and talk to virtually any model — in the cloud or on your machine.
100% Native
Built in Swift for Apple platforms. No Electron, no web views — instant launch and a low memory footprint.
All Major Cloud Providers
OpenAI, Azure OpenAI, Anthropic, Google Gemini, xAI Grok, Mistral AI, Groq, Kimi (Moonshot) and MiniMax.
Aggregators Built In
One key for hundreds of models via OpenRouter, Together AI or Replicate.
Any Compatible Endpoint
Point UChat AI at any OpenAI- or Anthropic-compatible server — including LAN or remote addresses.
Local & Offline
Run Ollama, LM Studio or the built-in GGUF engine entirely in-process. No API key required.
Reasoning & Images
Tune thinking effort per model and generate images right in the conversation where the provider supports it.
Not Just Chat. An Agent That Gets Things Done.
UChat AI puts real tools behind the models. Connect remote MCP servers, switch on any of the 12 built-in tools, or let the model run SSH operations on your servers — all inside one native chat window.
MCP servers, one click away
Add a streamable HTTP MCP server and UChat AI discovers its tools automatically, then hands them to the model alongside the built-in ones. Custom auth headers, per-tool switches, JSON import and automatic reconnect after network changes are all included.
12 built-in tools, on your terms
Fetch a URL, query RDAP or exchange rates, check the weather, read system info and time, resolve IPs from an offline GeoLite2 database, generate keys, wake a machine over LAN, or have the model create an image. Every tool is opt-in and stays inside the App Sandbox.
A real remote terminal toolkit
The SSH tool ships around 30 actions: run remote commands and capture their output, manage files over SFTP, inspect server status and control Docker containers. Credentials stay in the local database, so the model never has to ask for a password.
Works with the Models You Already Use
From first-party clouds to self-hosted endpoints — switch providers in seconds.

Each provider gets its own adapter
Anthropic speaks the Messages API, Gemini uses generateContent, Ollama talks to /api/chat, and local GGUF runs in-process through llama.cpp with no HTTP at all. Aggregators such as OpenRouter, Together AI and Replicate get their own credential scopes and model IDs, while Azure deployments and MiniMax's international and China endpoints are handled separately. Model lists, thinking and image-generation capabilities, and default parameters are detected per provider. OpenAI- and Anthropic-compatible endpoints are an extra option for self-hosted services — not a single pipe that every model is forced through.
