How guseul pen works

One pen, one box of beads — thread them however you like. And a shelf for the lines you find on the web.

  1. 1Thread beads

    Tap a bead in the box and it slides onto the pen, each new one stacking toward the cap. A pen holds up to 6.

  2. 2Pick up the pen and use it

    Tap the pen (or “Pick up the pen”). Your pen becomes the cursor: draw on empty space, select any line on this page and tap Keep — it lands in Kept lines. Press Esc or tap the pen to put it down. The extension does the same on every website.

  3. 3Rearrange

    Drag a bead along the pen to move it, and drag it off the pen to take it off. Tapping a bead still works too — Left / Right / Take off, or “Undo last” for the one you just added.

  4. 4Pen type, colour & charm

    Seven kinds of pen — pencil, ballpoint, gel, fountain, brush, highlighter, mechanical — and an ink colour for the ones that write in ink. Five barrel colours too, and a bunny, bear, sleepy cloud, berry or ribbon to hang on the end.

  5. 5Keep it

    “Wallpaper” saves the pen as a phone wallpaper with no watermark. “Put in case” keeps it and hands you a fresh pen. Tap any pen in the case to take it out and keep working.

  6. 6Keep lines from the web

    Install the browser extension, then select a line on any page and click Keep. Everything you keep turns up here, under Kept lines.

How do I set it as my wallpaper?

Tap Wallpaper → pick a background → Save image. iPhone: open the saved image → Share → “Save Image” to Photos, then in Photos tap Share → “Use as Wallpaper”. Android: open it in Gallery → “Set as wallpaper”.

Can I take a bead off?

Yes. Tap that bead on the pen, then Take off. To start over, use Take all off.
