Overview
Zuni is an AI assistant that runs in the Chrome sidebar and helps users work across Gmail, browser tabs, and web applications without constantly switching context. Its official site and Y Combinator profile describe it as a browser-based assistant that can use the contents of open tabs and Gmail context to answer questions, draft messages, and support writing workflows directly where the user is already working. Zuni gives access to multiple frontier AI models from providers such as OpenAI, Anthropic, Google, DeepSeek, Mistral, and Meta, while positioning itself as a productivity layer for communication and browsing tasks. It is aimed at professionals who want faster email drafting, contextual assistance, and a more integrated AI workspace inside Chrome.
