https://tafsir.app/ Seems like this website (think there might be a downloadable app also) has collated several famous tafseer works so posting here as it appears easy to use and handy for referencing etc. Only came across this as trying to practice Arabic via reading and the ones I looked through on this app have tashkeel including Al Qurtubi, ibn Kathir etc which helps a lot. I would warn that it also contains works by ibn uthaymeen, zamakhshari etc. I also obviously don't know if there's been any distortion as sometimes happens with texts published by salafis (I'm presuming those are the people who are behind this website).
