MLX-Serve is a private AI studio that runs entirely on your iPhone. Every conversation, voice recording, and generated image is processed on-device by open-weight models — nothing you type, say, or create ever leaves your phone. There is no account to create, no subscription, and no tracking of any kind. MUSIC Generate songs locally using your device ! You can also play it back in the background and use MLX-Serve as a player for your generated music on the go. CHAT Talk with capable open language models (Google Gemma 4) right on your device. Ask questions, brainstorm, draft messages, get things explained. Some models can even understand photos you attach. CALL Tap Call inside any conversation to talk to the AI hands-free, like a phone call. Your speech is transcribed on-device and the reply is read back aloud. Speaker and handset modes are both supported, and the transcript is saved to your chat. VOICE CLONE Record about eight seconds of your voice and have the AI speak text in your own voice, using an on-device text-to-speech model. Great for narration and fun. IMAGES Generate images from a text prompt with an on-device diffusion model (FLUX.2). Tap a result to zoom in, save it to your photo library, or share it. FULLY PRIVATE, FULLY OFFLINE - Runs 100% on-device using Apple MLX and the Metal GPU. - No account, no analytics, no ads, no tracking. - The network is used only to download the AI models you choose from Hugging Face. After a model is downloaded, that feature works offline. REQUIREMENTS Models are multi-gigabyte downloads and on-device AI is demanding, so MLX Chat requires a recent, high-performance iPhone. Download over Wi-Fi is recommended. You pick which models to download and can delete them anytime to reclaim space. Open models are provided under their respective licenses (Gemma, Apache 2.0). MLX Chat is an independent app and is not affiliated with Google or Apple.

Local LLM runs language models on your iPhone. No account is required. Chat, ask about photos, work with documents and use live voice. With Canvas, build websites, interactive pages and games from a conversation, then preview and edit them in the app. Features depend on the selected model. Download models from the catalog, or use Apple’s on-device model on supported devices when available. Core AI models require iOS 27 or later. Other supported models remain available on older systems. Inference and conversation history stay on your device. Model downloads, the catalog and model artwork use the network. Optional Web Search sends a query derived from your message to Tavily and may read result websites. Weather requests use Apple geocoding and WeatherKit for the requested city, without requesting device location. Voice input prefers on-device recognition. If it is unavailable or fails, Apple’s online speech service may process audio when network speech recognition is enabled. You can disable this in Privacy settings. Requires iOS 17 or later. Model availability depends on your device, OS, memory and storage. Downloads require internet; supported offline chat works after setup. Models can make mistakes. Do not rely on replies for medical, legal or financial decisions.
