tldr: GPT-powered hints on CF problems at https://hint.purduecpu.com. if you're scared of accidentally spoiling a problems when looking for hints, you can try this simple tool i made when i wanted a hint, which just pipes the editorial & some other data into gpt-4o-mini to get a hint of your choice (e.g. you can restrict the response to yes/no and ask if a data structure/algo is mentioned in the solution.)

sorry about the discord oauth -- i have like $6 in openai credits right now and don't want spam. thanks
