Persona.js and page-agent are two open-source JavaScript libraries designed to bring AI agent capabilities directly into web browsers. Persona.js offers a themeable, framework-agnostic UI widget for AI assistants, supporting features like streaming responses, voice I/O, and tool visualization, and can integrate with various backends including OpenAI's SDK and LangGraph. Page-agent, developed by Alibaba, takes a different approach by serializing the Document Object Model (DOM) to text, allowing any text-based LLM to control web applications through tool calls without needing multimodal models or a backend infrastructure.
