How WonderLine Works

1. DREAM IT & SAY IT
"A cat in space!"

Voice-Powered AI

Your child speaks, and WonderLine listens. No typing required.

2. WATCH THE MAGIC

Instant Generation

Gemini AI creates a custom, high-contrast coloring page in seconds.

3. LOCK & TRACE IT
Touch Disabled

Frustration-Free Tracing

Screen locks completely. Place paper on top and trace without accidental swipes.

Why Parents Love WonderLine

The perfect analog activity for a digital world.

Handwriting Hero

Generate instant tracing worksheets for any letter, number, or word. Simply say "Alphabet" or "Numbers 1-10" to practice writing.

Portable Light Box

Traditional light boxes are bulky and need outlets. Your iPad is already in your bag. Turn it into a tracing tool instantly.

Safe & Locked In

Kids can't trace on a normal photo app—the image moves! Our 'Lock Mode' freezes the screen so they can focus on creativity, not YouTube.

No More Printer Ink

Stop wasting expensive ink cartridges on coloring pages that get used once. WonderLine is digital-first, paper-second.
