Interactive Page System

A system for interactive web page assistance, comprising:

• a client device executing a browser;
• an embedded widget integrated into a web page displayed by the browser;
• a speech interface configured for automatic speech recognition and text-to-speech;
• a server comprising processors and memory storing models for natural-language understanding;
• and a page interaction index stored in memory accessible to the widget and comprising mappings between DOM nodes and associated metadata;
• wherein the widget is configured to:
• detect a web form in the DOM;
• derive per-field metadata including a label, input type, and validation rule from attributes or associated markup;
• present a voice-guided, step-by-step progression through the fields;
• confirm dictated entries by reading back slot values using text-to-speech;
• validate each entry against a corresponding validation rule;
• and, upon a validation failure, generate an in-context prompt that programmatically focuses the corresponding input element and instructs a correction, wherein the in-context prompt is recorded in the page interaction index as a mapping to a DOM node such that user selection of the prompt scrolls the associated field into view and applies a highlight.

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause a widget embedded in a product-listing web page to:

• scan the DOM for product containers;
• extract from each product container attributes comprising at least a title, price, and feature text;
• populate a dynamic comparison table rendered as an overlay within the current page;
• filter and rank rows of the comparison table in response to user criteria;
• and maintain for each cell a pointer to a source DOM node such that user interaction with the cell triggers highlighting of the node in the underlying page and updating of the cell when the node's content changes due to page scripts.
