Ai Gate

AI Gate is a free desktop app that brings web based AI assistants such as ChatGPT, Claude, Gemini and Perplexity into one window. Instead of juggling browser tabs, users arrange up to three tools side by side, switch between them with keyboard shortcuts, and keep each service signed in across restarts. It is designed for people who use several AI assistants every day and want to compare answers or move between them quickly. Layouts switch instantly between one, two and three panels, and each tool runs in an isolated webview with its own persistent session. Users can open several instances of the same tool, pin important ones, undo a closed panel and have the whole state restored automatically. Shortcuts cover layout changes, closing tools and undo, with custom hotkeys configurable in settings. External links open in the default browser while sign in flows stay inside the app. There are light, dark and system themes, a collapsible sidebar, a default layout setting, autostart, and in app update prompts. Because it wraps the existing websites, it needs no API keys; users simply sign in to the accounts they already have. The app is free to download for Windows 10 and 11, macOS on Apple Silicon and Intel, and Linux as an AppImage, with full access to all features. No paid plan is published, and the linked pricing page returns a not found error. The site notes that some features are still under development.
