Plain-English guides to each painting tool, refinement step, and slicer-readiness check. Written so you can read on the train, watch on a phone, or skim before you click.

Drop an STL, OBJ, or 3MF — or load the built-in demo to start.
Upload a photo, approve the sketch, print the figure. The first one's free.
No model yet? Describe one, or build it from a photo — it arrives ready to paint.
Three mouse buttons, three jobs. Plus one key that re-centres the view.
Switch the backdrop so your colours don't vanish into it.
Give it a photo or describe the colours; it paints the whole model, editable, ready to print.
Drag a line, rectangle, or circle onto the model — moves and resizes as a preview, paints with a crisp edge.
Stamp a logo, an image, or typed words onto the surface — printed as real colour with crisp edges.
Tap a part; it floods to the model's natural seams. Scroll to set how far it spreads.
Drag to paint by hand. Switch on Fine detail to catch recess walls without bleed.
Click a painted face and spread its colour outward, ring by ring. Stops at a different colour or a crease.
Drag to select a patch, then scope Clean speckles, Simplify, or Paint to just it.
Draw where one colour should stop. Click a crease to wall off a whole loop.
Eyedropper any painted face to reuse its colour. Or press I.
Chop the model along a line and hide the side that's in your way — then draw straight onto what's left.
Base-coat everything above or below a height in one shot.
Colour every face that points a given way. Bronze the tops, shadow the undersides.
Set how finely the model splits into paintable regions before you start.
Pull in real spool colours by brand — Bambu, Polymaker, Prusament and more.
One click loads a colour scheme: 40K factions, superheroes, wizards, sci-fi.
Swap every face of one colour for another in a single move.
Switch the active colour, or remove a chip and free its faces.
Mirror every stroke across an axis. Paint one side, the other follows.
Stand a sideways STL upright — rotate 90° and keep your paint.
Find paint narrower than your nozzle that the slicer would silently drop.
Tell the slicer which way the plate faces — it drives layer and swap analysis.
See filament swaps per layer so a print that'll crawl is obvious before you slice.
Slice along the build axis and scrub layer by layer.
Merge coplanar triangles to shrink the file and lighten the slicer's load.
Don't Ctrl+Z forty times. Pick the moment in the history and jump there.
Drop a concept image behind the model and match its colours.
.layerpaint files round-trip everything. One Save As, then silent saves.
Ship a Standard 3MF that opens already-coloured in Bambu, Orca, and Prusa.
