there is extension for browsers rikaikun/rikaichan and it offers translation of japanese sites. idk if it forks for pictures, but it might help, i believe you are thinking about something similar
also, it's better to learn kanji a different way xD a lot of people are recommending "Remember the kanji" by James Heisig

AWESOMEEEE! The pain of reading manga withour furigana is real! I have been writing it out with mouse to translate! If you can develop an app like this it will be awesome! I fully support this! Don't hesitate to ask me for help if u need any~~

You should go for it.

Thanks so much for the positive feedback. It's like a personal project so I'm still working on this idea. If you guys have any suggestion then don't hesitate to let me know. So far I'm considering these 2 options:
1. Incorporate a dictionary (something like the online jisho.org) into a manga reading app that has the image-to-text function. Drawback: Might not be accurate especially if the quality of the raw scans is only subpar.
2. Make it like the Youtube comment system. You know anyone can contribute subtitles on Youtube right? So I'm thinking, what if there's a platform that allows readers who know Japanese to contribute to a word list / kanji list specifically for each manga series (and I will somehow incorporate them into the raw scans themselves). One advantage is it can be more accurate, and we can easily include grammar explanations. Drawback: pretty much manual, might take a long time, and some people might not take this seriously.
One wild (and still pretty farfetched) vision I have is to be able to collab with the publishers in Japan and get the original manga texts from their database, but now I have no idea how to do that yet LOL
I'm just one person so of course my ideas are limited. Any feedback at all is appreciated!
Hey guys, I'm learning Japanese by myself especially by reading Japanese raws. I've noticed that (for me) it's time consuming to look up kanji in the dictionary in general, especially when there's no furigana to tell you the readings. I either have to use the image-to-text function in google translate, or writing out the kanji by hand using handwriting keyboards. I'm thinking of developing an app that builds kanji/word meanings into the raw manga themselves (so like, you can just tap on the words/kanji and see the popup definitions). Possibility to add grammar usage tips as well. What do you guys think? I need feedback from people who are trying to learn Japanese through manga as well. :) This is very important to me. Thanks a lot
If it's needed, I can create an online survey and you guys can comment on it.
