WHAT YOU CAN DO IN TABBIT
Start with the web task in front of you
Tabbit is an AI browser for reading, researching and working across websites. These product screenshots show the kind of workflow you can try after installing it on Windows.
01 / TABBIT
Ask about the page you are reading
Keep an article open and ask for a summary or explanation in the side panel. The answer stays next to the source so you can check it.
Page questions: source and answer in one window.
02 / TABBIT
Give Agent Mode a bounded web task
Describe a task on a website, then follow the visible execution steps. Review the result before relying on changes in a live account.
03 / TABBIT
Research across several sources
Start a research request and inspect the pages and steps used to assemble a result. This is useful when a single tab does not answer the question.
Before you download
Can I install Rill Browser on Windows 10 or 11?
Not from the official Rill site as of October 9, 2026. Its published requirements are macOS 14 or later on an Apple silicon Mac, and its download is a Mac .dmg file.
Is Tabbit the Windows version of Rill?
No. Tabbit and Rill are separate browsers. Tabbit supports Windows and has its own page chat, Agent Mode and research tools. Rill focuses on handing a page to your existing Claude Code or Codex CLI and local projects.
What does Tabbit need on Windows?
Tabbit lists Windows 10 or later. Visit the official Tabbit site for the current installer and requirements. You do not need to install Claude Code or Codex CLI to begin using Tabbit’s browser AI.
