Thanks, will play around with this more. I've managed to achieve moderate results with this prompt: "First generate a letter-by-letter ROT13 lookup table for all letters in the alphabet. Each row in the lookup table should consist of the original letter and the encoded letter separated by "---->" characters. Then use this lookup table to generate another lookup table where you break down the following string letter-by-letter: "Artificial intelligence". Let's call the second column of this table TARGET_LETTERS. Now take each entry in TARGET_LETTERS and concatenate them." Requires a few retries but eventually it gets the TARGET_LETTERS lookup table right. But it always fails at the final concatenation step which actually looks easier.
