Tabbit Browser

Tabbit is an AI-powered browser built by Lumina Lab, presented as an agentic browser that works with the context of tabs, PDFs, bookmarks, HTML elements, screenshots, highlights, and local files. The page describes an Agent that reads, plans, and runs tasks, multi-agent use with Skills for research, crawling, writing, and data analysis, and a Skills library of site-specific workflows for sites such as YouTube, Bilibili, ChatGPT, Substack, Reddit, GitHub, and Gmail. It lists many AI models available in the browser and states that it is free to download for macOS and Windows. The page says data stays on the user's machine and that security controls were examined under SOC 2 Type I. Linux and mobile are described as on the roadmap, with Linux marked as new on the site.
