As answered by people managing JSFiddle and Sideconvo.
Sideconvo's answer:
Sideconvo is a zero-config AI agent that allows visitors to have a real-time voice conversation with your website. Unlike standard text chatbots, Sideconvo listens and speaks back fluently in any language. It also features a "Missed Answers" dashboard that helps site owners identify content gaps based on what the AI couldn't answer.
Sideconvo's answer:
Choose Sideconvo if you want voice interaction without the code. While competitors like Intercom are text-only, and tools like Vapi require developer setup, Sideconvo offers a drop-in solution: - Voice-First: It adds accessibility and a "human touch" that text widgets lack. - Zero-Setup: It auto-crawls your URLs and reads your PDFs to train itself instantly—no manual decision trees required.
