Tabbit Browser

What Tabbit Browser is

Tabbit Browser is an AI-native browser from the company Lightyear Beyond, presented as a workspace browser that brings an AI assistant into every page rather than bolting it on. It is advertised as free for macOS and Windows.

What you can do with it

Wherever you are in the browser you can summon an AI that understands the page you are looking at, and the product pairs that with an Agent mode for longer tasks, an all-purpose input box for asking across context, saved tips called MiaoZhao, and vertical tabs for managing many pages, so the loop is browse, ask, act. It ships with built-in AI models so you do not have to wire up an API key to start, and the assistant is meant to help with the task in front of you, from summarising a page to acting on it. The download page emphasises a free, no-invite start on desktop operating systems.

Who it is for

It suits everyday desktop users and knowledge workers who want an always-available assistant while browsing.

A few things worth knowing

It is free to start, but with built-in models and an Agent mode that can act on pages, the privacy question is whether your page content and prompts leave the device, so read the privacy policy before leaning on it for confidential work. The Agent mode that performs tasks implies permissions over tabs and content that you should scope, and the reviewed material provides no clear security certification or data-retention statement, so confirm how context is handled and where it is stored. Because it is a full browser, switching means trusting it with your browsing history and sign-ins. Read the policy and scope the Agent before confidential use.
