Why there are different meaning for a sentence? I'm beginner

"Isst du das noch auf" means "are you going to finish that" in memrise,"Are you still going to eat that?" in Google translate. But my gut say it's about the last part of food who is gonna eat? I don't know which sentence is correct.

I seen some AI like gemini, GPT are shit at teaching things about a concept to people. there just give a chunk of information about the thing we are searching for... "I think that's dangerous that learn the concept - Alexander pope"

for example: Let's say we run error into a code or a problem instead of giving me the answer or summary of why its doesn't work.

I want the AI to explain the same concept or the API definition and the pitfalls things i need to careful like that. I think that the real "augmentation".

Is there any AI tools which can help a concept to learn from deep dive without buch of AI prompt
