About Tool

ChatTab is designed to deliver a fast, minimal and privacy-focused interface for interacting with AI models on macOS. Instead of using a browser, users install a lightweight client that supports multiple model APIs (e.g., GPT-4, Claude) and centralises conversations in one place. It solves the problem of juggling browser tabs, subscriptions and slow performance when working with AI chats by offering a native experience with shorter latency, better window management and optimized UI. The tool also emphasises local data safety, storing API keys securely and reducing reliance on external login flows. Whether you’re a developer, researcher, writer or power user, ChatTab aims to make AI chat quicker, easier and more controlled.

Key Features

• Native macOS app for chatting with multiple AI models (GPT-3.5, GPT-4, Claude, etc)
• Multi-tab interface to manage several conversations at once
• Keyboard shortcut access and minimal memory footprint
• Local storage of prompts, API keys in Keychain, and optional iCloud prompt sync
• Markdown support, multilingual UI and seamless UI design
• Lifetime license or pay-as-you-go token plans available

Pros:

• Streamlined, fast and distraction-free desktop experience compared to browser-based chat interfaces
• Supports a broad range of models, giving flexibility and experimentation possibilities
• Strong privacy focus: data stored locally, no login required, API keys handled securely

• The minimal UI and setup may still require some configuration from less tech-savvy users

Who is Using?

ChatTab is ideal for developers, AI researchers, prompt engineers, content creators and power users on macOS who regularly interact with AI models and want a dedicated desktop application. It’s especially useful for those who switch between models or manage many chat streams and prefer native app performance over browser tabs.

What Makes It Unique?

ChatTab stands out by combining a truly native macOS experience with support for multiple AI models in a unified interface and a strong privacy-first approach.
