Sound familiar?

"I want a Rubik's cube mosaic but mapping colors by hand takes days"

"Free tools won't let me use MY colors or MY size"

"I have the pattern… now how do I build it without getting lost?"

Every weekend without that mosaic on the wall is another "someday". And the hours you spend mapping colors by hand are hours you don't build.

“We believe the creative part is building with your hands — not fighting color spreadsheets. From pixel to piece: the machine does the math, you make the art.”

🤲 For humans, not for robots

Kai BuildArt turns images into instructions for a person to build by hand. We don't generate files so a machine makes the piece on its own: the finished work always carries your touch.

Kai BuildArt solves the whole journey

Who is this for

✓ Mosaic builders (Rubik, LEGO, beads) who want the exact pattern and shopping list.

✓ Stitchers and knitters who need real codes (DMC) and professional PDFs.

✓ Makers with lasers, 3D printers or Cricut who want ready files (SVG, DXF, STL).

✗ Looking for a pixel-by-pixel drawing editor like Photoshop? That's not us — we start from an image and make it buildable.

Frequently asked questions

How much does it cost?

Converting is free forever (up to 50×50 cells). Paid plans start at $9 USD/month and unlock big grids, pro exports (paginated PDF, SVG, CSV, STL, DXF) and the BuildArt Kit. Annual gives you 2 months free.

How is this different from the free tools out there?

Three things you won't find together: inventory mode (use ONLY the colors and quantities you own), an interactive piece-by-piece Build Mode, and 46 media in one tool with fabrication exports. Plus everything runs in your browser: real privacy.

Does my image get uploaded anywhere?

No. The engine runs in your browser. Only if you save a project do we store a reduced copy (max 512 px) so you can reopen it on other devices.

Do I need design or tech skills?

No. Upload an image, pick your material and move simple sliders. The app calculates colors, quantities, costs and guides you piece by piece as you build.

What are KaiCoins?

The currency for AI features (generate designs, advisor, guides). Normal conversions never spend coins: they're free and unlimited.

Can I sell the patterns I generate?

With the Workshop plan yes, with an explicit commercial license. Other plans are for personal use.

How do I pay?

Card or local payment methods via dLocal Go (coverage across LATAM and beyond). Monthly subscription or one-time annual payment.

What happens if my plan expires?

You get 5 days of grace. Then you drop to Free: nothing is deleted, extra projects become read-only until you reactivate.

How does inventory mode work?

You tell it how many units you own per color and the engine distributes the pattern without exceeding your stock.
