est. 2005 Lab notebook for AI, attribution, and machine intelligence.
Writing, experiments, and field notes from Joel Citron — building enterprise AI systems by day, prototyping at the edge of the model after hours.
About
Started in 2005. Still building.
Began as a creative director in 2005, pivoted to development in 2008, and have spent the last decade-plus marrying the two — building enterprise attribution systems at AI Media Group, where I'm now CTIO.
The thesis hasn't changed: a design-trained engineer makes better technical decisions because they think about the human standing in front of the system, and a engineering-trained designer ships things the design-only crowd never finishes. acidlemon is where I write about both sides.
