About off-grid-mobile

Off Grid AI is an open-source React Native app that runs large language models (LLMs), vision models, and Stable Diffusion entirely on-device on iOS, Android, and Mac, with no internet required. It supports text generation (Qwen 3, Llama 3.2, Gemma 3, Phi-4, and custom GGUF files), image generation, vision AI (image analysis), voice transcription, tool calling, and document analysis. All processing happens locally; no data ever leaves the device. An optional Pro tier ($69 lifetime or $49/year) adds on-device text-to-speech (Kokoro), custom personas with persistent memory, and integration with Calendar, email, and MCP servers (Linear, Notion, GitHub) for draft-and-approve actions. Pro also enables secure local network sync between phone and Mac.
