LM Studio explains that shorter documents can be added directly to the conversation. For longer material, the application may instead retrieve parts that seem relevant to the question. This makes large texts more manageable, but also means an answer does not guarantee that every page has been considered.
Ask focused questions and check the answer against the original. “Which times are mentioned?” is easier to verify than “Tell me everything important.”
This can be a good way to get to know both a document and the tool’s limitations. Start small, keep the original beside you and treat AI as help with searching rather than a new answer key.
