# Sparkle

> Sparkle builds high-converting popups, forms, and an AI chatbot for any website — then a self-optimizing AI engine writes your CTA, tests five angles, and locks onto the winner with statistical significance. Install in one line of HTML, or let an AI coding agent install it for you over MCP. No code required.

Sparkle is a hosted conversion toolkit (popups, forms, AI chatbot, payments, A/B testing) served from Cloudflare's edge. Your leads and payments stay in your own accounts — captures sync to your ESP/CRM and payments land in your own Stripe balance. There is no vendor lock-in.

## What Sparkle does

- Popups & forms: exit-intent, scroll-depth, time-on-page and per-URL targeting; modals, slide-ins, bars and fullscreen — all responsive.
- Self-optimizing AI CTA: reads your page, drafts the five most compelling angles, cycles them past real visitors, and auto-promotes the winner once it reaches statistical significance.
- AI chatbot: a chat bubble grounded in your own instructions (Cloudflare Workers AI) that answers questions and captures the email.
- Payments: drop a Stripe payment field into any form — one-time or subscription — with funds landing in your own Stripe account.
- A/B testing: pit variants against each other with real statistical significance and promote the winner in a click.
- Integrations: Mailchimp, Klaviyo, HubSpot, Beehiiv, Salesforce, Attio, Twenty, Slack, Google Sheets and more, plus Zapier / Make / n8n / Windmill webhooks.

## Install

- One line: paste one `<script>` tag before `</body>`. Works on WordPress, Shopify, Webflow, Next.js, Wix, Squarespace, Framer, Astro and any site.
- Via AI agent: a public MCP server lets Claude Code, Cursor, Codex or Grok provision and embed Sparkle for you.
