What is Claude?
Claude combines natural language dialogue with file processing. You can provide a task objective, background information, and the desired format, first obtaining a modifiable result, then refining it through follow-up questions to supplement details, adjust the structure, and refine the expression. Compared to simply receiving a single answer, this approach is better suited for real-world tasks that require multiple rounds of refinement.
When working with data, you can upload supported documents or images in the chat, and you can also organize related files around the same project. When reading PDFs, compiling interviews, or analyzing spreadsheets, it’s advisable to clearly define the content you need to extract, the format of your conclusions, and their corresponding sources; the integrity of the original materials will directly affect the output.
After enabling file-creation capabilities, Claude can generate or edit files such as Word, Excel, PowerPoint, and PDF. The generated results still require manual review, especially regarding numbers, citations, formulas, and key conclusions. Account plans, organizational settings, and the tools that are enabled also affect the actual available capabilities.
