Chat, not action
Most built-in sidebars can summarize a page, but they stop when real work begins: filling forms, comparing sources, or running multi-step workflows.

O Melhor Navegador com Barra Lateral de IA

Done. I found 3 conflicting claims and drafted a structured report with citations.
The problem
A maioria das barras laterais de IA são apenas painéis de chat.
They answer questions, but they cannot execute. They ask you to copy context, and they sit next to a tab bar that falls apart under pressure.
Copy-paste context
You still switch tabs, copy snippets, and paste them into a chat box. The sidebar does not know what you are looking at unless you tell it.
Tabs take over
A horizontal tab bar collapses under research load. The AI sidebar becomes another window to manage instead of a command center.
What makes Tabbit different
Conheça a Agentic Sidebar
Tabbit rethinks the browser around the sidebar. It is where you chat, navigate, organize tabs, and delegate work—without leaving your flow.
Vertical tabs + AI sidebar in one
A single sidebar holds your tabs, workspaces, and AI. Full titles stay visible, tabs auto-group by topic, and the AI sees the whole workspace.
Omnibox for URLs and tasks
Type a URL, ask a question, or assign a task from the same box. No need to switch between address bar and chat panel.
Context with @ mentions
Reference any open tab, tab group, webpage screenshot, bookmark, or local file. Tabbit uses it as context instantly—no copy-paste.
Agent mode runs in parallel
Tell the sidebar to research, fill forms, or aggregate data. It executes in its own tab group while you keep browsing uninterrupted.
