The AI-powered vertical tab manager for a tidier browser
Move your open tabs out of the cramped top bar and into a full-height sidebar where titles and favicons are easy to read.
Let the extension cluster related tabs automatically with AI, so research or project sessions stay grouped without manual sorting.
Nest tabs under parent tabs and drag them between groups to mirror how you actually think about your work.
Built for Chromium-based browsers including Chrome, Brave and Edge, so your setup travels across the browsers you already use.

AI-native browser that understands your context and runs agent tasks
Reference tabs, tab groups, local files, highlighted text, whole pages, or screenshots as context with a single @ or one click, so you never copy-paste background material again.
Describe a routine in plain language and Tabbit's agent opens pages, fills forms, and carries out repetitive operations for you.
Choose among several leading models including DeepSeek, Kimi, GLM, MiniMax, Doubao, Qwen, and LongCat depending on the task.
Tabs are automatically grouped, categorized, and summarized in a vertical sidebar, making dozens of open research pages manageable.
