Rainline vs. Browser-Based AI Chat Apps
Browser apps are convenient, but they come with trade-offs. Here's how Rainline compares on privacy, performance, and power-user features.
Browser-based AI chat tools like Claude Desktop and Chatbox.ai have made AI accessible to millions. But if you’re a macOS power user, a native app can offer advantages that browsers simply can’t match.
Privacy
Browser apps run inside a sandbox, but they still store session data, cookies, and sometimes full conversation history in the cloud. Rainline stores your API keys in the macOS Keychain and runs tools locally.
Performance
Rainline is a native macOS app. That means global hotkeys, menu bar access, and keyboard-first navigation without the overhead of a full browser runtime.
Extensibility
Thanks to MCP support, Rainline can mix and match 200+ tools from different providers. You’re not limited to a single vendor’s ecosystem.
