Zuni

Zuni is a Chrome sidebar extension that provides contextual AI assistance across a user's browser tabs, using what it can see on open pages as context to draft emails, messages and replies. It gives fast access to multiple frontier AI models within the browser sidebar, and stores chats locally rather than on its own servers for privacy. Built by co-founders Will and George, it was part of Y Combinator's Summer 2024 (S24) batch. It targets knowledge workers who want an always-available AI copilot integrated directly into their browsing workflow.
