What wasn't working.
A consulting business wanted a 24/7 first-response assistant on their marketing site that could answer "what do you do?" and "what does it cost?" without burning budget on a full live-chat team or an enterprise chatbot platform. Most AI chat widgets are overpriced, locked to specific platforms, or grounded in generic data that hallucinates the business's actual offering.
How we built it.
A lightweight Cloudflare Workers backend that proxies to the Anthropic API with a system prompt grounded in the business's service descriptions, pricing, and tone. A vanilla JavaScript widget that drops into any page via a single script tag. Lead capture triggers automatically when a visitor asks about pricing or says they want to talk to someone real. Captured leads get forwarded to the business's CRM.
What shipped.
- Running cost under $5/month for typical traffic (Cloudflare Workers free tier handles most requests)
- 24/7 first-response for visitor questions — no more missed leads from after-hours traffic
- Context-aware responses grounded in the actual business knowledge base — no hallucinations about services or pricing
- One-line install: drop the script tag on any page and the widget appears
- Analytics dashboard on visitor questions to surface content gaps in the marketing copy
