ChatGPT is used for explaining lesson concepts, solving exercises, writing and editing text, generating ideas, summarizing documents, analyzing Excel files and interpreting charts. The Deep Research feature is designed to perform multi-stage research and report preparation based on online sources. File and data analysis capabilities also allow users to examine data, find possible patterns, and receive results in the form of explanations or graphs.
