Frequently Asked Questions

On Device AI runs 170+ language models (Llama 3, Gemma 3, Qwen 3, DeepSeek, Phi-4, Mistral) directly on your iPhone, iPad, Mac, or Vision Pro using GGUF and MLX inference engines. All processing happens on your device with zero data collection. No internet required for core features.
Yes. Once you download a model, voice transcription, document analysis, AI chat, Knowledge Libraries, vision models, and text-to-speech all work without internet. Cloud AI providers are available as opt-in additions but disabled by default.
170+ models including Llama 3, Gemma 3, Qwen 3, DeepSeek, Phi-4, and Mistral. You can also import custom GGUF models from Hugging Face. The app uses both llama.cpp (GGUF) and MLX inference engines for broad compatibility on Apple Silicon.
You deploy specialized AI agents that collaborate on a single task. A Researcher gathers information, an Analyst evaluates it, a Writer produces the output. Each agent can use a different model and role. The whole workflow runs locally on your device.
iPhone 14 and newer, iPad mini 7th gen and newer, iPad Air 5th gen and newer, iPad Pro 3rd gen and newer, iPad 11th gen and newer, all Apple Silicon Macs, and Apple Vision Pro. Devices with 6GB+ RAM provide optimal performance.
Yes. On Device AI supports 19+ cloud providers including OpenAI, Anthropic Claude, Google Gemini, Groq, OpenRouter, Nvidia, LM Studio, and Ollama. Cloud is off by default and requires your explicit configuration. You can mix local and cloud models in the same conversation.
Project-specific document stores. Import PDFs, notes, web captures, and images into a Library. The AI retrieves and answers questions sourced from those documents using on-device embeddings. Your files never leave your device.
Yes. Local vision models using both MLX and GGUF engines, plus cloud vision APIs as opt-in. Analyze photos, screenshots, diagrams, and documents with OCR text extraction, all processed on your device.
Yes. ChatGPT sends your data to OpenAI's servers for processing. On Device AI runs models directly on your hardware. No data collection, no accounts, no analytics, no telemetry. Your conversations never leave your device during local processing. ChatGPT has stronger frontier reasoning capabilities, but if privacy matters to you, local processing is the only real guarantee.
On Device AI runs 170+ models on Apple Silicon Macs with both GGUF and MLX engines. Mac-specific features include menu bar access, global hotkeys, IM integration for Discord/Slack/Telegram, and the ability to serve as a remote inference server for your iPhone and iPad.
Yes. Voice transcription includes speaker diarization, which identifies who said what during meetings, interviews, and conversations. It runs on-device using a Whisper-based speech-to-text engine. No audio is sent externally.
Yes. The Kokoro TTS engine generates natural-sounding speech offline on your device. You can read aloud PDFs, articles, or AI responses without internet. Multiple voice options are available.
GGUF models use llama.cpp and work across a wide range of hardware with broad model compatibility. MLX models are optimized for Apple Silicon and can offer better memory efficiency. On Device AI supports both, so you can pick the right engine for your device and workload.
On Device AI includes IM chatbot integration for Discord, Slack, and Telegram on macOS. Your Mac acts as the inference server, so messages are processed locally on your hardware rather than a cloud server.
Unlike cloud-based AI that sends your prompts to remote servers, On Device AI runs entirely on your hardware. No data collection. No analytics. No backend. No internet required. The core features are free forever. If you need Pro functions, you can choose what works best for you: a monthly or annual subscription, or a one-time purchase to own it outright. Every option is priced lower than ChatGPT.
