Private & Powerful AI: Your Choice
Transform speech to text and chat with advanced AI models without sending data away. Run leading open-source models 100% offline or connect to cloud providers when you need extra power.
- 100% On Device: Run top models like Llama, Gemma, Phi, Qwen, and DeepSeek locally, optimized for Apple Silicon with MLX and Llama.cpp Engine.
- Cloud Capable: Optionally connect to providers like OpenAI, Anthropic, Gemini, Groq, OpenRouter, LM Studio, and Ollama in one unified interface.
- Hybrid Workflow: Switch between local and cloud models inside the same conversation, maintaining clear data ownership.
Knowledge Libraries for Serious Projects
Version 1.33.0 introduces Knowledge Libraries, a dedicated AI memory for each project, client, or research topic. Group the right files and let your AI assistant focus only on the context that matters.
- Create a Library for each project to group PDFs, notes, web captures, and images.
- Use "library aware search" so answers are sourced directly from your active Library.
- Manage all Libraries from a single view with document previews and metadata.
Collaborative AI Teams
Create sophisticated AI teams where specialized agents work together on complex tasks. Move beyond single-turn chats with multi agent workflows.
- Deploy built in teams for business strategy, academic research, and creative projects.
- Example: Use a "Market Analyst" + "Strategic Planner" + "Risk Assessor" team for business planning.
- Configure custom multi agent flows with decision making processes, perfect for complex problems.
Complete Voice, Speech & Translation Suite
Capture ideas and create professional audio with a full voice workflow.
- Instantly record and transcribe meetings, lectures, or voice notes.
- Generate natural, professional quality speech from any text using Apple voices or the advanced Kokoro voice engine.
- Effortlessly translate languages and get AI generated summaries with natural voice narration.
- Reuse previous recordings with different models for new summaries or deeper analysis.
Smart Document, Vision & Web Understanding
Bring external knowledge into your AI workflow securely.
- Use local vision models to understand photos, diagrams, and screenshots on-device.
- Tap into cloud vision models for even richer analysis when you choose.
- Analyze PDFs, text files, and images with OCR to extract insights and summarize reports.
- Use built in web search and page by page reading mode to let AI read sources and return structured answers.
Deep Apple Ecosystem Integration
Enjoy a native experience across iPhone, iPad, and Mac, optimized for Apple Silicon.
