ChatGPT, an AI model, can be used to summarize articles by copying the URL of the source material and asking it to summarize the contents. However, its ability to do so is hit or miss, and users need to refine their prompts to get accurate summaries. The model has limitations, such as a token limit that restricts the length of the summary, and can produce less-than-accurate answers. To use ChatGPT effectively, users must specify what to include in the summary and consider the potential for oversimplification. Additionally, there are workarounds available to summarize videos and websites, although these may require paid upgrades or custom models. Users can also automate the process of generating AI article summaries using OpenAI and Zapier.
