The Difference
What Sets Tabbit Apart from Dia?
Dia Browser, built by the Arc team, puts an AI assistant in your address bar. It is great for quick summaries and chatting with tabs. But it stops at assistance — it does not truly act on your behalf.
Tabbit is a fully agentic browser. It not only understands pages but also performs multi-step tasks autonomously: researching across sites, filling forms, drafting emails, and synthesizing every open tab. Plus, Tabbit is a multi-model aggregator — switch between GPT, Claude, Gemini, DeepSeek, Kimi, and more inside one browser.
