FOMOChat is an AI chat widget that adds social proof and an AI company representative to a website. Visitors join a live group chat where an AI rep trained on the site content answers questions instantly, while AI-generated participants ask the questions visitors are thinking, so answers arrive while social proof builds. The chat can sync to a video or webinar timeline, so reactions and answers appear at the right moments in a pitch, and site owners set facts and guardrails so the rep adds qualifiers when unsure instead of inventing information. Setup needs no code: configure personas, product context, and conversation style, generate the conversation, and paste one embed snippet to go live in under five minutes. The free Preview plan covers 100 lifetime visitors and 400 AI chat messages with a branded badge, a $1 one-time Production plan removes branding, and monthly plans start at $29 for 500 visitors. It suits SaaS pages, courses, and product launches chasing more trial sign-ups.
