I've gotten some questions about panelcleaner and how it works, so I've just made some screenshots here over how to use it.
First you'll just load the files or folders. Default is cleaning (Panel Cleaner is a program that uses OCR to clean panels after all), so you'll have to switch to OCR. For OCR, using default settings is fine. You might need to tweak it a little to get cleaning to work if you want to use it for that.
After OCR has been finished, you'll be able to manually go through and correct mistakes in ordering and writing. Here it's really helpful to have some hiragana, katakana, and general kanji knowledge. Panel Cleaner which uses Manga OCR is a bit worse on handwritten text than google lens, so you might want to double check any text that's handwritten.
Easiest and best way to translate the finished text file is usually uploading it to an LLM like chatgpt or gemini, I prefer gpt. If you log into chatgpt you get a somewhat better model which is worth it in my opinion, you only get like 10 free uses a day but it's enough for a few chapters. You might also want to ask chatgpt to break down sentences if you can't figure out the sentence (not seldom it has used the wrong meaning of a kanji, or like for handwritten text it has gotten a kanji wrong).
