01 — Why Customei
Not a feature list — the handful of things competitors cannot match in a sprint, and the numbers merchants see when they switch.
Star maps computed from a real date and place. String art solved from a customer's photo. Crosswords, word clouds, word searches and maps — all first-class layers, not bolt-on templates. This is the part competitors cannot copy in a sprint.
See the generatorsA bezier warp mesh bends artwork to the real surface and displacement maps push it into the weave, the glaze and the seam. Fewer “this isn't what I saw” refunds, on the one product category you cannot resell.
How warping works02 — The studio
Ten tools, each with its own page — the demo, the specifications and the honest limits. Every one is here because it fixed a real merchant's real problem.
Drag warp handles so the print follows a mug's curve or a sleeve's seam. Mask it with the pen tool. Every mockup angle refreshes as your customer types.

Every other personalization app gives you “add text to a tee”. These five exist because specific print-on-demand categories make real money from them — each one is a solver, not a canvas trick.
Render the exact night sky for any date and latitude / longitude. Merchants sell these as anniversary, wedding and birth-night prints.
“We tried six personalization apps in 2024. Customei is the only one that did not crumble on mobile Safari. The rest is a bonus.”
04 — Platforms & fulfilment
The studio, the generators and the print pipeline are platform-agnostic, and Customei takes no cut of production. Here is exactly what is live, and where a paid order's artwork lands.
Where it runs
How a paid order reaches your printer
Named one-click integrations with specific POD networks are in progress. Until then, every partner that can read a bucket, an API, a link or a webhook is already supported.
05 — Solutions
A phone-case store and a multi-brand retailer share almost nothing except the word personalization. Two pillars, ten standalone pages, each with its own demo and its own numbers.
