How Thinking works

Documents and photos

Attach a PDF or text to a chat and ask about it, or add documents to your Knowledge library and turn on Use My Library. Vision models can look at photos; otherwise SoloLLM reads the text in a photo with on-device OCR.

Documents and photos

Tools, Agent mode and MCP

Models that support tools can run code in an on-device sandbox, read files and add calendar events. Agent mode can plan the steps, and it waits for your OK before a sensitive one.

Tools and MCP

Private by default

No account, no ads, no analytics. Offline only stops every network request with one switch, and the Network Log shows each request SoloLLM makes.

Short answers

Common questions about AI on your iPhone.

Can I run an LLM on my iPhone offline?

Yes. SoloLLM runs open-weight language models such as Qwen3.5, Gemma 4 and Llama 3.2 directly on your iPhone or iPad. You download a model once, and after that chat works with no internet connection. Bigger models need more memory, so SoloLLM shows which ones fit your device before you download.

Is SoloLLM private?

Yes, by default. Models run on your device, there is no account, and the app has no ads or analytics. What you type stays on your device unless you use a feature that goes online, such as web search, Cloud Mode or your own servers. The Offline only switch blocks every request.

How is SoloLLM different from the ChatGPT app?

The ChatGPT app sends your messages to OpenAI's servers, where the model runs, so it needs a connection. SoloLLM runs the model on your iPhone or iPad, so chats work offline and stay on the device. Models small enough for a phone are smaller than the ones behind cloud assistants, so their answers are usually simpler.
