Like millions of others, I use ChatGPT daily. As a power user, I frequently use ChatGPT to summarize research, create images and I even use the bot to talk me down from a spiral of indecision.
But recently, I revisited an underused setting buried in the app that completely changes how the bot responds. It’s so useful that I really wish I had taken advantage of it sooner — though there’s one caveat: it also makes AI output much harder to detect.
No, it’s not a secret plugin or a pro-only feature. It’s something that’s been there the whole time: custom instructions.
