ChatTab is a native macOS desktop app that makes working with ChatGPT and other AI models fast and convenient right on your Mac. It uses the OpenAI ChatGPT API and supports multiple models, including GPT-3.5, GPT-3.5-16k, GPT-4, GPT-4-1106, GPT-4-Vision, GPT-4-32k, and Claude 2.
Native ChatGPT client for Mac
Built specifically for macOS, ChatTab focuses on a lightweight, responsive interface with minimal system load. Instead of keeping ChatGPT open in a browser tab, you can keep your chats and prompts in a compact desktop app.
Use your own or a built-in API key
ChatTab can connect with your OpenAI API key, or you can use a built-in key to get started quickly without signing in to ChatGPT. This setup is useful for people who rely on AI regularly in their workflow.
Who it’s for
ChatTab is a fit for users who value speed, stability, and a native macOS experience, including:
