Ignoring this crazy discussion above
, I've been following the development of Zenpy since the beginning, and I can say with certainty that it is one of the best automatic translation tools for Renpy games that I've come across! Not only is it capable of translating all existing dialogue in games, including answers (which in many games end up remaining in English), it also has an extractor included that is capable of locating all those intro texts, messages and quests that they always end up being left out in translations using more manual methods (such as Dark Light or Extractor palOsliOs, CG7 with Translate Renpy).
Furthermore, the program is VERY simple to use, you just need to select the languages you want to translate, define whether you want the separate files as in the original languages or everything together, and that's it, just start the translation and wait no more than half minute in most games. Now, of course, it's not 100% perfect and there may be some game or other that will end up buggy, but in most cases, it's a game that Zapo doesn't know yet and it's always available on Discord to see reports of bugs and make improvements.
This program has a lot of potential, and is definitely worth the BRL 40 (which is around US$ 8.13 or EUR 7.44)
PS: I hope this comment is understandable, my English is still very weak
