# SparkGPT > SparkGPT is an AI sales agent for your website. You paste your store URL and in > about 10 minutes it builds a Claude-powered agent that answers customer questions, > recommends products, and guides shoppers to checkout. It works with Shopify, > WordPress, and any website. Built on Anthropic's Claude. No coding required. ## Pricing - Free: build and test one agent, no credit card. Cannot go live (no deployable widget, no Analytics). - Growth: $49/month base + 5% of the sales the agent drives (attributed sales). If it drives no sales, you pay just $49. Example: $2,000 in attributed sales = $49 + $100 = $149. - Done-For-You: custom pricing, full setup and brand-matched design. Contact support@sparkgpt.ai. ## Key facts - Outcome-based billing: a low $49 base plus a small 5% cut of sales it actually drives — not a flat $100–$400+/month regardless of results. - Conversion attribution: when a visitor chats, the session is tagged; any purchase within 24 hours is attributed to the agent and shown in the ROI dashboard. - Billing is prepaid credits (1 credit = $1) with optional auto-recharge; if the balance runs out the agent pauses instead of charging unexpectedly. No contracts, cancel anytime. - It sells, not just answers: greets visitors, recommends products, handles objections, guides to checkout, and can redirect visitors to specific pages. - Setup: paste your store URL, the agent is built automatically, go live with one line of code or a one-click Shopify install. ## Links - Home: https://www.sparkgpt.ai - Pricing: https://www.sparkgpt.ai/pricing - FAQ: https://www.sparkgpt.ai/faq - Compare vs Chatbase: https://www.sparkgpt.ai/compare/chatbase - Blog index: https://www.sparkgpt.ai/blog - Blog — Add an AI agent to Shopify: https://www.sparkgpt.ai/blog/add-ai-agent-to-shopify - API documentation: https://www.sparkgpt.ai/docs/api ## Contact - Support: support@sparkgpt.ai
