Off Grid
The Swiss Army Knife of On-Device AI
Chat. Generate images. See. Listen. All on your phone. All offline. Zero data leaves your device.
Not just another chat app
Most "local LLM" apps give you a text chatbot and call it a day. Off Grid is a complete offline AI suite — text generation, image generation, vision AI, voice transcription, and document analysis, all running natively on your phone's hardware.
What can it do?
Text Generation — Run Qwen 3, Llama 3.2, Gemma 3, Phi-4, and any GGUF model. Streaming responses, thinking mode, 15-30 tok/s on flagship devices. Bring your own .gguf files too.
Image Generation — On-device Stable Diffusion with real-time preview. NPU-accelerated on Snapdragon (5-10s per image), Core ML on iOS. 20+ models including Absolute Reality, DreamShaper, Anything V5.
Vision AI — Point your camera at anything and ask questions. SmolVLM, Qwen3-VL, Gemma 3n — analyze documents, describe scenes, read receipts. ~7s on flagship devices.
Voice Input — On-device Whisper speech-to-text. Hold to record, auto-transcribe. No audio ever leaves your phone.
Document Analysis — Attach PDFs, code files, CSVs, and more to your conversations. Native PDF text extraction on both platforms.
AI Prompt Enhancement — Simple prompt in, detailed Stable Diffusion prompt out. Your text model automatically enhances image generation prompts.
