This script facilitates the display and collection of user feedback through surveys directly on a website or web application. It handles the rendering of survey widgets, captures user responses, and transmits this data to Langfuse's backend for analysis and evaluation. The script may also manage survey presentation logic, such as determining when and to whom a survey should be shown, and might store temporary state regarding user interactions with surveys to prevent repetitive displays or to save partial responses. It's instrumental for product teams looking to gather direct user sentiment and evaluate the performance or perception of features, especially in the context of AI-powered applications. Langfuse typically provides observability for Large Language Model (LLM) applications. Therefore, this survey script is often used to gather specific feedback related to the quality, relevance, or user experience of AI responses or features.
