On Device AI is your Secure Data Vault.|
Private workflows for iPhone, iPad, Mac, and Apple Vision Pro.
Stop sending your private files, transcripts, and daily work to remote servers. Ask questions, index PDFs, record speaker-labeled meetings, and trigger multi-agent actions on device. Fast, offline-ready, and 100% private.
190+ local models · No account · No analytics · Works offline after model download
Choose the Private AI Workflow You Need
Start from the job you want done. Each path links to a focused guide or use-case page with the details.
Run Local AI Privately
Download a model and chat offline with GGUF or MLX models on Apple hardware.
Analyze Private Documents
Use Knowledge Libraries to ask questions across PDFs, notes, images, and web captures.
Record And Summarize Meetings
Transcribe audio locally, label speakers, and turn recordings into notes and action items.
Build An AI Team
Use Chat Flows and specialized roles for research, analysis, writing, and review workflows.
Connect Optional Cloud Providers
Bring your own provider when a task needs remote frontier models. Cloud stays off until you configure it.
Use Local AI On Vision Pro
Bring private AI chat, web search, and spatial workflows to Apple's immersive platform.
Clear Claims, No Credibility Theater
The site only uses proof we can point to: product docs, legal pages, screenshots, and public app surfaces.
No account, analytics, or telemetry
Local AI processing is designed around device-local storage and processing. See the Privacy Policy.
Documented local workflows
Core workflows have public guides for Knowledge Libraries, Voice Notes, Chat Flows, and Text-to-Speech.
Free download, optional upgrades
Start with local workflows. Pro features and cloud providers are optional, and cloud providers require explicit configuration.
How It Compares
On Device AI is not trying to replace every cloud assistant. It is built for privacy, offline use, and Apple-native local workflows.
Vs. cloud AI assistants
Cloud assistants can offer stronger frontier reasoning. On Device AI gives you local processing, offline workflows, and control over when cloud providers are used.
Vs. basic local LLM apps
Many local apps stop at chat. On Device AI adds Knowledge Libraries, Voice Notes, TTS, vision, tool calling, and Chat Flows.
Vs. cloud transcription tools
Cloud transcription is convenient. On Device AI focuses on private local recording, transcription, speaker labels, and follow-up AI actions.
Vs. multi-model clients
Multi-model clients make switching providers easy. On Device AI adds local-first workflows, private files, and native Apple-platform coverage.
Complete Model Freedom & Control
Built for developers, researchers, and professionals who need native speed, model choice, and true data privacy.
190+ Local Models & 19 Cloud APIs
Never get locked into a single ecosystem. Run Llama, DeepSeek, and Gemma directly on your device with dual GGUF and MLX engines. Need massive reasoning capabilities? Instantly switch to OpenAI, Anthropic, or 19+ other cloud APIs when connected.
Multi-Agent Teams
Orchestrate specialized AI agents that collaborate autonomously. Assign distinct roles and models for complex tasks.
Knowledge Libraries
Your documents, your memory. Import PDFs and notes to create focused contexts. The AI retrieves answers securely locally.
Pure Native Ecosystem
A unified native app optimized for macOS, iOS, iPadOS, and visionOS. Turn your Mac into a private local inference server to run heavy models, then access it securely from your iPhone. No sluggish web wrappers or Electron bloat—just responsive, GPU-accelerated Swift code.
What Can On Device AI Do?
Powerful AI features right on your device, with no network dependency. Say goodbye to privacy concerns.
Subagents & Workflow Automation
Multiply your productivity. Deploy specialized agents (e.g., Researcher, Analyst, Writer) that consult each other to tackle complex projects simultaneously across your devices.

Voice Notes & Transcription
Record or import audio to transcribe and summarize meetings directly on your device. Local speaker identification (diarization) automatically labels who said what, giving you clean minutes without sending confidential audio to the cloud.

Frequently Asked Questions
What Power Users Are Saying
Real feedback from developers and privacy advocates who use On Device AI daily.
Best app for AI in 2025
"From on-device AI to advanced search and text-to-voice, this is one of the best AI applications I’ve found. Recent updates made the UI much easier to understand and use. 10/10 would recommend."
Great 5/5
"Great application. I recommend it. It allows me to run AI locally on my iPad Pro M2. The update added French, my language, and it works perfectly. Locally means it runs with the power of your device, not on a server, so it can work without Wi-Fi."
Insanely open and configurable
"The amount of freedom this app gives you for changing models and configuring them is much more than even some desktop LLM apps. It can run decent models on 6GB devices like the iPad A16 or iPhone 13 Pro Max."
I love you dev
"It’s amazing. It lets you choose from a huge selection of models, search the internet, communicate like a proper assistant, and do deep searches. It can also connect to a computer for more processing power."
Good app
"Feature-rich, with a large variety of models."
