What It Is

PyGPT is a free, open-source desktop AI assistant for Windows, macOS, and Linux that brings the power of multiple AI models—including OpenAI GPT-5, GPT-4, o1, o3, Google Gemini, Anthropic Claude, xAI Grok, DeepSeek, Perplexity, and any models from Ollama or LlamaIndex—directly to your desktop. Written in Python, it operates locally on your computer while connecting to cloud AI services, giving you a ChatGPT-like experience with extensive customization and control.

Who It's For

PyGPT is designed for developers, researchers, power users, and anyone seeking a flexible, privacy-conscious AI workspace. It's ideal for those who want to experiment with multiple AI models, integrate AI into local workflows, automate tasks, or build custom AI-driven solutions without vendor lock-in. The platform also includes accessibility features—customizable keyboard shortcuts, voice control, and text-to-speech—making it suitable for individuals with disabilities.

Key Features and Capabilities

• 12 Modes of Operation: Chat, Chat with Files, Realtime + Audio, Research (Perplexity), Completion, Image and Video Generation, Vision, Assistants, Experts, Computer Use, Agents, and Autonomous Mode

• Accessibility and Localization: Supports 18+ languages, customizable themes (light/dark), keyboard shortcuts, voice control, and on-screen action translation to audio

Typical Workflows and Use Cases

PyGPT excels at automating repetitive tasks, conducting in-depth research with Perplexity and advanced models, generating code and executing it locally, analyzing images and documents, managing files and attachments, and orchestrating multi-step autonomous workflows. Users can build custom agents, integrate AI into existing tools via plugins, schedule tasks via cron, and leverage internet access for real-time information retrieval.

What Differentiates It

Unlike web-based AI assistants, PyGPT runs on your desktop with your own API keys, giving you full control over data, costs, and configuration. Its open-source nature (MIT License, available on GitHub) means you can inspect, modify, and extend the codebase. The platform's plugin architecture, MCP support, extensive integration options (API, CLI, desktop app, Snap, PyPi), and ability to work with virtually any AI model provider make it a highly adaptable foundation for custom AI workflows.
