Self-hosted AI workspace for local and cloud models
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.

Browser-native LLMs at your fingertips, private and offline
Large language models are packaged inside the extension and executed in an isolated browser sandbox, so no server, account or API key is required to get started.
Every request is served from your own machine, which keeps your prompts and data off third-party servers and lets the tool keep working when you are offline.
Websites and extensions can request access to your model through the window.ai interface, turning the browser into a shared AI runtime for web apps.
You decide which applications are allowed to talk to your model, and you can review the history of prompts and responses made across different apps.
