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.

Free, on-device AI tab grouping for a calmer browser
On-device AI sorts dozens of open tabs into logical categories automatically, so related research and reading stay together.
Instantly close duplicate tabs opened more than once, so the same article does not appear six times in your tab bar.
Clear out tabs you opened weeks ago and forgot about, so long-neglected tabs do not pile up.
Everything runs 100% locally, with the developer disclosing that no data is collected or sold, so your browsing chaos stays private.
