I use ChatGPT to romanize song texts from Farsi squiggly lines into something readable. There are some other sites that do that, but they are all terrible and use regex replacement (I assume) and that doesn’t really work for most things since vowels in Farsi (and Arabic too) are diacritics and are often left out entirely, so you get something unreadable. ChatGPT does a fine job, but you have to make multiple, smaller requests instead of a single big one or it starts hallucinating and/or repeat passages it already romanized.
