Window
Browser extension that puts you in control of which AI model powers your apps

Window bridges web applications and AI services, putting users in the driver's seat of model selection. Instead of developers embedding specific API credentials into their code, you decide which AI provider powers each app you use.
Highlights
- Switch between AI providers—OpenAI, Google, Anthropic, Together, Cohere—without restarting apps
- Run models locally on your machine for complete data privacy and offline capability
- Automatic conversation history maintained across browser sessions
- Developers build AI features once; users pick their preferred model
- Zero backend management of API keys or credentials
Built for web developers who want to offer AI functionality without vendor lock-in or infrastructure burden. Ideal for users who care about which AI system processes their data and want the freedom to switch models. The extension is free to install; ongoing costs depend on which AI services you subscribe to.
