How this channel uses the term 'n=1' software names the practice of building software for an audience of exactly one — yourself. Instead of commissioning a tool or waiting for a product to exist, you make the small piece of software you personally need, using AI to make that economical. In the channel's material, this idea shows up in the conversation with writer and photographer Craig Mod, who describes rebuilding expensive tools himself rather than buying them, with AI doing the heavy lifting of the coding. The point is not to ship a product; it is to solve your own problem, at your own scale, and to understand the tool in the process. That is why the term sits inside the Writing with AI chapter: for writers, 'n=1' software is a practical answer to the question of what AI is actually good at right now — not drafting prose, but building bespoke utilities around the writing life.
