Yemma 4 is a private AI chat app that runs entirely on your iPhone. It runs Google's Gemma 4 locally through a Swift-native MLX multimodal runtime, so your prompts, images, and responses stay on your device. There is no account to create, no cloud inference service in the middle of your conversations, and no telemetry pipeline watching what you do. Download the model once, then keep chatting on Wi-Fi, cellular, or in airplane mode. Ask questions, brainstorm ideas, rewrite text, summarize notes, describe photos, and have real back-and-forth conversations with image attachments, all processed on-device. Why Yemma 4 feels different: - 100% on-device AI chat - No sign-up, login, or subscription - Offline after the initial model download - Local conversation history you can delete any time - Adjustable response style and creativity controls - Image understanding through the same on-device model Hardware note: - Requires iPhone hardware with the A17 Pro chip or later - First model download is about 4.2 GB, so Wi-Fi and free storage are recommended
