Extensión ChatGPT
Rápida de instalar, pero el contexto es limitado y sigues gestionando pestañas a mano.

GPT integrado · Agent Mode · Gratis en Mac y Windows
Tabbit es un navegador con ChatGPT integrado — no un complemento lateral. Pregunta sobre cualquier página, cambia a Claude o Gemini y deja que Agent Mode termine tareas de varios pasos en su propio grupo de pestañas.
Elige tu camino
Rápida de instalar, pero el contexto es limitado y sigues gestionando pestañas a mano.
Barra lateral nativa y búsqueda inteligente — primero macOS, solo modelos OpenAI.
GPT integrado, ejecución Agent, cambio de modelos y espacios verticales en Mac y Windows.
Cómo funciona
Escribe una URL, pregunta o tarea. GPT lee la página actual — sin copiar y pegar entre pestañas.
Referencia pestañas, capturas, PDFs o colecciones. ChatGPT responde con tu flujo real a la vista.
Cuando el chat no basta, Agent ejecuta formularios e investigación en un grupo aislado — en paralelo a tu trabajo.
