Best AI Assistant 2026
Best AI Assistant
Tabbit puts a context-aware AI assistant inside your browser. Ask about any page, automate repetitive tasks, and keep your tabs organized—without switching apps.

> "Find the best flights to Tokyo, compare prices, and open the top 3 results in new tabs."
Tabbit reads the page, runs the comparison, and opens results while you keep working.
One Assistant. Every Page.
Most AI assistants live in a chat window. Tabbit lives where you already work—the browser.
Want an assistant that just works?
Tabbit is a free, downloadable browser with built-in Agent Mode. No API keys, no extensions, no scripts.

Tabbit understands the active tab, selected text, and open tabs as context.
Ask or command
Type naturally or use @ to reference a page, screenshot, or file.
Agent completes it
Tabbit clicks, scrolls, fills forms, and opens results across multiple tabs.
