Video reference
Tutorials, recordings, screen-shared meetings - keep them visible while you do the work in another app. Coding from a YouTube tutorial, editing video to a reference clip, watching a demo while filling out a doc.
What people use PipZ for.
PipZ shows up wherever you need a stable second screen on the screen you already have. These are the workflows it gets used for the most.
Documentation sidecar
API references, internal guides, runbooks, and checklists float over your IDE or design tool. The thing you keep alt-tabbing to is now just there, in the corner, while you work.
Dashboard monitoring
Grafana, Datadog, CI status, admin panels - anything you keep glancing at - stays in view without tab switching. Combine with auto-refresh to get a near-live view that updates on its own.
Slides on the side
Take notes from a slide deck, follow a webinar while writing in your doc, or keep your own preview deck visible while you present from another window.
Whatever you want, really.
The four above are the patterns that come up the most, but a PiP window is just a generic floating browser tab - it doesn't know or care what's inside. A chat thread during a deploy. A recipe page while you cook. A chess board. A meditation timer. The kid's show during a long call. The rule is "always visible without taking the foreground" - what you put there is yours.
