The Ultimate AI Assistant for Your iPhone. 100% Offline.

Tired of AI That Only Works Online?

Using AI on your iPhone is powerful, but traditional apps come with serious limitations. You need a stable internet connection, your private data is sent to third-party servers, and complex setups are often required. For iPhone users who value privacy and need reliability anywhere, the standard solutions just don't work.

No Internet, No AI: Stuck on a plane, traveling abroad, or hiking off-grid? Your AI assistant disappears when you need it most.
Data Privacy Risks: Every question you ask is processed on someone else's computer, creating a record of your sensitive information.
Complex & Technical: Trying to run an open-source model like Llama on your iPhone often requires technical knowledge, complex apps like Ollama, and manual configuration.

Frequently Asked Questions

Can I really run a powerful LLM like Llama on my iPhone?

Yes. Modern iPhones with Apple's A-series chips are incredibly powerful. OfflineGPT is optimized to use this hardware efficiently, allowing you to run sophisticated quantized models directly on your device with impressive speed.

Do I need an internet connection at all?

You only need an internet connection one time to download the app and your chosen AI model. After that, the entire app and all its AI capabilities work perfectly 100% offline.

Is this secure? How is my privacy protected?

It's the most secure way to use AI. Since the model runs locally on your iPhone, your data is never sent to an external server. All processing and conversation history stays on your device, guaranteed.

Which models can I use? Is it compatible with Ollama?

OfflineGPT supports a wide range of the most popular open-source models in GGUF format, the standard for local LLMs. This includes various versions of Llama, Mixtral, Gemma, and more. While you don't need Ollama, our app makes it easy to run the same types of models on iOS.
