    Unpaywall primarily focuses on research articles, so other types of academic content like book chapters or conference proceedings may not be available.

    > can you detail what the possible issue is? Why? Are you in a position to help everyone? (As you probably guessed while reading the comment you replied to, I don't really need help; more on that below).

  • I am fuckin tired of every other short or video of being about another useless gpt promt or extension. Please give me better trusted resources
    There are many of course the problem is that the ai hallucination problem is still a huge issue. For instance, getting all of https://unpaywall.org/ or something similar into an LLM would be a boon for scientists, but... If you can't trust what it is saying you will end up going back to pull the source anyway. The analysis it provides would probably be helpful though. Source: about 3 years ago
