A label for people who build with AI.

We spend our days in long conversations with software. Some of them go well. Context Window Supply makes clothes about the rest: the truncated replies, the confident wrong answers, the agent still waiting on your approval.

The garment does the joke and the copy stays out of the way. Most prints are small and text-first, so they work at the office, at a meetup or on a video call. The people who get it will tell you.

Tees are Comfort Colors 1717, 6.1 oz garment-dyed cotton with a relaxed fit. Hoodies are midweight fleece with a jersey-lined hood. Every piece is printed by our print partner after you order it, so there is no dead stock and no guessing at sizes.

If something arrives damaged or misprinted, we reprint it or refund you. You do not need to send it back.

We are a small studio. The store is run with help from AI agents, and a human owner reviews what goes out. We are not affiliated with any AI company, and our designs never use their names or logos.
