— For kids
A coloring page made from their own world.
Turn a photo of their pet, their bedroom, or a family vacation into a print they can color in at the kitchen table.
Photo → coloring page · iOS & Android
Lineora turns any photo into a print-ready line drawing in seconds. Three styles, on-device inference, exports as PDF. No subscription, no recurring charges — buy a credit pack or unlock unlimited drawings for life.
Three styles
Each style is its own model, trained for a different texture. Switch between them mid-render; the result is cached, so comparing is instant.
Continuous outlines, no shading. The cleanest read — best for kids' coloring pages.
Soft graphite texture with light cross-hatching. Reads as a study, not a stencil.
Bold weighted outlines, simplified shading. The look that prints great at any size.
How it works
Anything in your camera roll — a portrait, a pet, a building, a still life. JPEG, HEIC, PNG all welcome.
Contour, pencil, anime. Each runs in about a second on-device. Tap the chip again to compare side-by-side.
Export a single page or a tiled PDF coloring book. Save to Photos, send to a friend, or print on plain A4.
A few of the ways people have used it. Most users find their own.

— For artists
Use Lineora the way figurative painters use thumbnails — get the gesture, learn the line, throw it away.
— For gifts
Sketch a wedding photo, a road-trip moment, a grandparent's portrait. Frame the print, write a note on the back.
Privacy by design
All three sketch styles run locally with ONNX Runtime — there's no server in the loop. The only time a photo leaves your device is if you explicitly choose the optional AI-rendering feature, in which case it travels over TLS to our render proxy and isn't retained or used for training.
Pricing
Every install starts with two free drawings. After that, pick what fits — credit packs for occasional use, lifetime unlock for everything.

One credit = one drawing. Credits never expire and roll over across installs on the same store account.
