Connect Ollama or LM Studio to a Phone

Local-server mode lets your phone send prompts to a model endpoint you run yourself, such as Ollama, LM Studio, or another OpenAI-compatible server.

This is different from on-device local mode. The request leaves the phone and travels to the server address you entered, usually on your own Wi-Fi network.

Why use a local server

A desktop or laptop can run larger models than a phone. Local-server mode gives you a calm mobile interface while the heavier model runs on your own machine.

This can be useful for longer planning sessions, code help, or larger reading tasks.

Basic setup

Make sure your phone and computer are on the same trusted network. Start your server software and confirm it accepts connections from other devices on the network.

In Phos, add the server URL, test the connection, and select the model exposed by that server.

Keep the boundary clear

Do not expose local model servers directly to the public internet unless you know how to secure them.

Local-server mode is private only to the extent that your network, server, and model software are private. Phos should show this as a user-run endpoint, not as company-hosted inference.
