The ChatGPT Prompt That Makes AI Sound Human
Most ChatGPT responses are easy to spot — bullet points, em-dashes, random emojis. This one Custom Instructions prompt tells ChatGPT exactly what to do, what to avoid, and forces it to check its own output. Paste it once and every response sounds human by default.
