I built GhostTab: AI agents drive my real browser as text, in a hidden tab

说明与用途

GhostTab 让 AI 代理通过隐藏标签页中的文本控制真实浏览器，节省令牌并避免屏幕占用。

问题

Screenshot-based browser agents were slow, expensive, and intrusive, taking over the screen.

结果

In one day, an agent used GhostTab to submit ~40 job applications on LinkedIn Easy Apply and Greenhouse, improving speed and reducing token cost by 5–10×.

工作流

证据

Screenshot-based browser agents were slow and expensive for me, and they kept taking over my screen.

A screenshot costs roughly 1,500 tokens. A compact text view of the same page, with numbered elements, is usually a few hundred.

This week my agent used it to fill and submit about 40 job applications (LinkedIn Easy Apply and Greenhouse) in one day.

macOS only for now (AppleScript plus an optional extension bridge for background real input). Free and open source (MIT).
