DescriptionThis JavaScript snippet manages the website's theme based on user preferences. It retrieves the user's theme preference from localStorage; if the preference is 'system' or not set, it checks the system's theme setting via the 'prefers-color-scheme' media query. Depending on the outcome, it applies either a dark or light theme to the document. For explicit 'light' or 'dark' preferences, it directly applies the corresponding theme. Error handling is also incorporated to ensure smooth operation.ChatGPT, crafted by OpenAI, marks a significant leap in AI language technology, excelling in human-like text processing through natural dialogue. The platform's rapid success is underscored by its adoption by over a million users shortly after launch.

Integration involves API access, adjusted for computational demands, and supports RAG systems using vector databases. The recent enterprise version and pro tier offer advanced privacy, customization, internet integration, and improved voice interaction.
