Dark / light aware icons: No visual clutter, no CSS conflicts. Dynamic Content Ready: Works seamlessly inside single-page apps, iframes, and with dynamically added form fields. HOW IT WORKS Scan & Identify: The script scans visible form elements and extracts the best “key” (label, placeholder, ARIA attributes, etc.) to understand the field's context. Secure API Query: These keys are sent securely to our API. Intelligent Response: For individual field tooltips: Depending on your plan, we return a stored, curated tooltip or generate a fresh one with OpenAI. For the Question Assistant: Your typed questions are sent to the API, which leverages our knowledge base and AI to provide answers. Clear Display: The tooltip, including the optional audio button, appears in an isolated shadow-DOM container to prevent style conflicts. The Question Assistant opens in a clean, modal window.
