About
On-Device AI: TTS, STT & Chat is a comprehensive local artificial intelligence suite designed for the Apple ecosystem, including iPhone, iPad, Mac, and Vision Pro. Unlike standard AI assistants that rely on cloud servers, this tool prioritizes privacy by executing large language models (LLMs) directly on the user's hardware. It supports a variety of leading open-source models such as Llama, Gemma, and DeepSeek, allowing users to engage in text-based chat, visual analysis, and voice-to-text transcription without ever sending sensitive data to external servers. This architecture makes it an ideal choice for users working with confidential information or those requiring AI assistance in environments without stable internet connectivity. The application offers a multi-layered feature set that extends beyond simple chat. It includes advanced Chat Flows for managing multiple contexts and AI Teams where specialized agents collaborate on complex tasks. For power users, the tool integrates Active Tools like web search and a calculator to provide real-time data and precision. On macOS, the app introduces IM connectivity, enabling users to bridge their local AI with platforms like Discord, Slack, and Telegram to automate replies and manage conversations. The suite is rounded out by a high-performance speech-to-text engine and natural-sounding voice generation using the Kokoro engine, all optimized for Apple Silicon through the MLX and Llama.cpp frameworks. This tool is specifically tailored for privacy-conscious professionals, researchers, and developers who require a secure, local-first AI workspace. Developers can leverage the app's deep integration with Apple Shortcuts and Siri to create custom automated workflows, while content creators can use the vision and transcription features to process media locally. It is also well-suited for users with high-performance Apple hardware, such as M-series Macs or the latest iPhones, who want to maximize their device's processing power. The inclusion of cloud provider support for OpenAI and Anthropic ensures that users can still access massive models when local resources are insufficient for a particular task.

FAQs
Which local AI models are supported by the app?
The app supports several leading open-source models including Llama, Gemma, Phi, Qwen, and DeepSeek. These models are optimized for Apple Silicon using MLX and Llama.cpp engines for maximum performance.
Does the app require an internet connection to work?
No, the core chat and processing features work 100% offline for local models. Internet access is only required for initial model downloads, cloud provider connections, or the integrated web search tool.
What are 'Active Tools' within the chat interface?
Active Tools allow your AI agents to perform specific tasks beyond conversation, such as conducting real-time Web Searches or using a Calculator for precise mathematical operations.
How does IM Connectivity work on the Mac version?
The Mac app can connect directly to Discord, Slack, and Telegram. This allows you to automate replies and manage your communications using your local AI context without leaving the application.
What hardware do I need to run this app effectively?
You need an iPhone or iPad with an A12 Bionic chip or later running iOS/iPadOS 17.0+. While it runs on older supported devices, larger 8B models perform best on hardware with more RAM, like M-series iPads or Macs.
