The present invention relates to a system for transforming static websites into artificial intelligence (AI)-enabled interactive multi-modal conversational platforms. The system comprises a computing device having a processor for receiving user queries as text or speech input through an input module cooperating with a speech-to-text module. A natural language processing (NLP) module interprets intent, classifies user context, and retrieves grounded information from multiple webpages. A persona adaptation module dynamically modifies vocabulary, tone, and avatar representation across roles such as sales assistant, recruiter, educator, healthcare professional, etc. A response generator module produces structured natural language output, transmitted to a text-to-speech synthesis module and an avatar generation module to render synchronized lifelike video responses. An output rendering module displays multi-modal responses include text, audio, and video, thereby enabling direct navigation and escalation beyond limitations of conventional static websites.

Systems and methods are provided for intelligent website user journey recommendations. Contextual user information, of a user accessing a page of a website containing content items, may be identified. The contextual user information and content information for the content items may be input into a model that generates a sequence of content items to recommend to the user. An interface element of the website is populated with one or more content items from the sequence of content items. The interface element may be dynamically updated with content items as the user navigates the website. In this way, the user can directly navigate to the recommended content items through the interface element.

A user inputs indicates a first destination with a wide level of specificity. A mobile device navigates towards a first location 104 corresponding to the first destination. While navigating towards the first location 104 is ongoing and before reaching the first location 104, if a first criteria is satisfied, the mobile device prompts 108 for an input for determining a second location 110 corresponding to a second navigation destination with a second level of specificity. If the second input satisfies a second criteria, the mobile device directs navigation towards a second location corresponding to the second destination. Preferably, the first criteria includes an indication that the specificity level of the first location defines an area larger than a threshold area. Or a confidence parameter may be below a confidence threshold. Or the first location may cover a geographical area that is accessible by multiple routes (e.g., highways). Preferably, the second criteria comprises the second level of specificity being more specific than the first level of specificity.
