Privacy AI is both a chatbot and an agent, and both run on your device. Ask it a question, or give it a goal and it will plan, use tools, and come back with a report. Local models work fully offline, and nothing leaves your phone unless you connect a cloud provider yourself. Run Models Locally or in the Cloud - On-device GGUF and MLX models, with vision and tool-calling - New on iOS 27: Neural Engine models keep generating after you leave the app - Local Decisions: classify and rate text on device, no text generated - Apple Private Cloud Compute and the on-device Foundation Model, no account or API key - Apple models read attached pictures; models without vision get an on-device description - Connect to OpenAI, Claude, Gemini, DeepSeek, or any OpenAI-compatible server Agent - Give it a goal and it keeps working across as many turns as that takes - It plans first, calls tools, keeps its own folder of files, and delivers a written report - Suited to work that must be broken down: deep research, a multi-leg trip, comparing options - Teach it with Skills: folders of instructions and scripts it can call by name Chat - Set model tiers once (fast, capable, reasoning, local), then just type - Smart Chat routes each message by complexity and privacy, and keeps sensitive text local - Switch local and remote models mid-conversation, keeping context System Keyboard - Bring Privacy AI into any app: dictate by voice, or rewrite, translate and reshape text in place - Build named pipelines (Polish then Translate) or use presets like Proofread - Types in 11 languages with Pinyin, Japanese and Korean input Mini Apps - Doc Scanner: turn a PDF, photo or camera scan into clean Markdown, tables and equations intact - Email Assistant: triage any IMAP inbox on device, with a dated report you can undo - Knowledge Wiki: a cross-linked knowledge base from your documents, with cited answers - LLM Council: query several models in parallel and synthesize one answer - Custom assistants with instructions, an avatar, and a knowledge base Tools - 60+ built-in tools: web search, news, calendar, code execution and more - Full MCP support with a marketplace, Siri and Shortcuts Writing and Voice - Long-form writing assistant that drafts outlines and chapters - Text to Audio: turn a document into a single audio file using on-device voices - Real-time voice chat and live transcription Files and Content - Convert PDFs, Office files, EPUB, video and audio to Markdown, with OCR - Media Studio: generate images with your provider Accessibility - VoiceOver support, sound and haptic feedback, Verbose Announcements - View Assistant: point the camera and hear what is in front of you Free to Use.
