How does model switching preserve context?<\/h3>\n<p>Chattydesk maintains the complete message history in its database and includes it in subsequent prompts, regardless of the selected model.<\/p>\n<h3>2. Is my API key stored securely?<\/h3>\n<p>Custom API keys are stored in the client state and only transmitted directly to OpenRouter via the backend proxy.<\/p>\n<h3>3. What platforms are supported?<\/h3>\n<p>The Electron app supports Windows, macOS, and Linux, while the web version works on any modern browser.<\/p>\n<h2>Conclusion &#038; Next Steps<\/h2>\n<p>Chattydesk represents a significant leap forward in AI model accessibility, offering developers and power users unprecedented flexibility in model comparison and usage.
