Integration · Local models
Let a local model use your iPhone.
Run an open model on your own Mac with LM Studio and let it use your iPhone through ScreenTap. Everything stays on your machine: the model, the screen and your data.
Set up
LM Studio
Runs open models on your Mac and supports MCP servers (version 0.3.17 and later).

Pick a model that can use tools
Load a model with tool-calling support, enable ScreenTap for the chat, and ask:
PromptTake a screenshot of my iPhone and tell me what's on screen.
Things to try
Ask a local model to…
- ›
Take a screenshot of my iPhone and tell me what's on screen.
- ›
Open Settings and turn on Dark Mode.
- ›
Read my latest text messages and summarize them.
More in the prompt library.
Good to know
- The model needs tool-calling (function calling) support, and it must understand images to read screenshots.
- Small local models handle simple tasks well but can struggle with long, multi-step ones. Larger models do better.
- Ollama doesn't run MCP servers by itself; use an MCP-capable app on top of it, or LM Studio.
Questions
Can a local LLM control my iPhone?+
Yes. LM Studio supports MCP, so a local model with tool calling and vision can use ScreenTap to see and control your iPhone, fully offline.
Is it private?+
Fully: the model runs on your Mac, ScreenTap runs on your Mac, and the screen never leaves it.
