What Is a Word Card Picture-in-Picture?
The Word Card Picture-in-Picture tool uses the browser's Document Picture-in-Picture API to turn traditional word cards into an always-on-top mini window. Whether you're writing code, reading docs, or working in a spreadsheet, the card floats above your windows and swaps to a new random word every few seconds — a frictionless way to build vocabulary.
Why Use a Floating Word Card?
- Always on top: The PiP window floats above everything else and stays visible even when the browser is minimized — study words while you work.
- Auto rotation: A new random word appears every 5 seconds by default, adjustable from 1 to 120 seconds.
- Full manual control: Switch cards with Previous / Next, or pause auto-rotation at any time.
- Reuses existing word lists: Pulls directly from the site's daily drills, unit lists, and cloud vocabulary tables.
How It Works
Traditional vocabulary review demands dedicated study time, which is easy to postpone. A floating card fits vocabulary learning into your daily workflow: during a build, a break, or a doc read, one glance at the corner of your screen is a mini review session. Randomized rotation with phonetics, meanings, and examples creates a high-frequency, low-effort, fragmented memorization rhythm.
Compatibility & Privacy
Document Picture-in-Picture requires Chrome / Edge 116 or later with a secure HTTPS context. If unsupported, the tool still works as a regular page and offers a popup-window fallback. All word data is loaded from this site; settings are stored locally in your browser and no personal data is uploaded.
