The Last Person Who Knew

Kept reads a company's incident reviews, specs, threads and whiteboard photos and answers why questions, with sources, and says "I don't know" when it doesn't. It sells to heads of engineering at companies that have been through two or three waves of hiring and attrition. The category talks about speed and generation, and buyers have learned to distrust both: an assistant that writes more, faster, and sometimes makes things up. We needed to show the cost of forgetting and the value of a cited answer without a single robot, orb, sparkle or "thinking" animation.

Companies forget the way houses do:

the people move out and the marks stay on the walls. Every office is full of traces of decisions: a wiped whiteboard, the dent of a pen in the page underneath, glue where the sticky notes were. Kept is the one that can still read them. The film follows a rule nobody can explain, "we don't ship on Thursdays", through three of those traces, and lets them redraw themselves in one marker blue. When the product answers, its citations come up in that same blue. Recovering a trace and citing a source become one gesture.

Thirty-six seconds, five daylight interiors in Hammershøi greys, cross-dissolves only. The plates were generated, then graded in code toward overcast light. Each trace is a hand-authored SVG path pinned to the residue in the photograph and revealed at writing speed, multiplied into the surface. The legal pad's indentations appear first as embossing, then as graphite. The product beat is typography only: a question in italic, an answer settling line by line, and two citations, each tied to its claim by a hairline. The felt-piano score is synthesised: a four-note phrase that breaks off when the question is asked and resolves once the answer has been given.
