We used Greptile where I work and it was so bad we decided to switch to Claude. And even Claude isn’t nearly as good at reviewing as an experienced programmer with domain knowledge.
I appreciate the prompt engineering effort, but it's a lot of claims and not much substance. Also, I wouldn't call Japanese used in anime "real Japanese", especially from anime like Attack on Titan. And how do you get around the copyright issue? Does this fall under fair use?
