What it does

Off Grid AI is a React Native app for running AI models on the device itself. Its README says it works offline, needs no account or API key, and keeps data on the device. It targets iOS and Android phones, and the iOS App Store version also runs on Apple Silicon Macs. For text it runs GGUF models such as Qwen 3, Llama 3.2, Gemma 3 and Phi-4, using the CPU, GPU or NPU depending on the device. It also covers on-device Stable Diffusion image generation, vision models that answer questions about camera images, Whisper speech-to-text, tool calling with built-in tools, and a project knowledge base for PDFs and text documents. It can connect to OpenAI-compatible servers on your local network, such as Ollama or LM Studio. An optional Pro tier adds on-device text-to-speech, custom personas, drafted actions that wait for your approval across Calendar, email and MCP servers, and sync between phone and Mac.
