PipZ

PipZ is a multi-window picture-in-picture tool for macOS.

That quickly floats content from any browser tab into an always-on window, keeping videos, documents, dashboards, slides, and temporary reference pages visible when switching apps. It supports direct invocation from mainstream browsers, can create windows with keyboard shortcuts, and also provides functions such as click penetration, transparency adjustment, window welt finishing, layout presets, and automatic refresh, making it convenient to keep the workflow continuous when writing code, doing design, viewing data, or monitoring data. PipZ can also be connected to the MCP client to control the opening, arrangement, dimming, and closing of windows through natural language, and supports the selection of individual elements directly from web pages as independent PiP content, suitable for Mac users who need to efficiently manage the browser context.
