The problem: it is now hard to tell whether a painting was made by a person or by AI. A finished image proves nothing, and a painter who films their process is still asking to be believed.

Piece of Mind gives a painting a memory of its own making that anyone can check. You film yourself painting with a phone on a stand. Meta's Muse Spark 1.3 decides what to track, SAM 3.1 tracks the painter, their hands and their tools through every frame, and the canvas is rebuilt only from pixels the camera saw, each stroke dated to the second it became visible. The models never generate or alter a pixel of the painting.

The result is a page per painting: watch it form without the painter in the way, sit beside it in a labelled composite, tap any stroke to play the camera's footage of the moment it was painted, or peel the painting back through its recorded layers. A receipt binds the page to the footage: a verification script re-derives every output frame from the footage and the cached model answers, bit for bit, with no model and no key, and fails if the footage is cut or swapped.

Artists have always taken new tools, materials and mediums into their work; some raise hard questions about authorship and authenticity. Piece of Mind brings AI into the artistic process without letting it touch the artwork: it documents and reveals how a piece came to be, so the work, its process and its authorship stay grounded in the real world. Built and tested on three paintings made during the hackathon (84, 52 and 61 minutes), on the Meta Model API and on open weights. Painting today; pottery and sculpture next.
