Anthropic Hackathon

Sitters won 1st Place at the Anthropic Hackathon in September 2026. I implemented a museum app that lets you point a camera at a painting and hold a voice conversation with its sitter, its painter, or both.

A museum app that lets you talk to a painting

Status 1st Place, Anthropic Hackathon. The demo’s answers are pre-written for now.

Context

At a museum you read a forty-word label, glance at the painting and move on. The people in the portrait can’t tell you anything.

At the Anthropic Hackathon in September 2026, I asked a simple question: what if you could talk to the person in the painting, to the painter, or to both?

What we built

My two teammates and I built Sitters, and I implemented the app myself. You point a camera at a painting and hold a voice conversation with its sitter, its painter, or both.

  • The idea. Talk to the person in a painting, to the painter, or to both.

  • The spec. Written before any code, with the rules below built in.

  • The build. A Next.js app with Claude and ElevenLabs, which I implemented.

  • The personas. Each one separates sourced answers from labeled speculation, with a curator layer for context.

The decision

Before any code existed, we wrote the rules into the build spec: no living people, no knowledge beyond the sitter’s lifetime, and anything not from the historical record would be marked as imagined.

I designed the conversational personas around those rules: each one separates sourced answers from labeled speculation, and a curator layer adds the context.

The demo

Our demo was Sargent’s Madame X, a portrait the painter and the sitter felt very differently about.

For now the demo answers from a pre-written script.
