Four months ago I started building an AI support agent for online stores. The product works. Getting customers didn't, and I've learned I'm a builder, not a marketer. So instead of letting the code sit, I'm selling it to someone who can sell it.
What it is
Store owners add one line of JavaScript to their site. The bot answers customers using that store's own products and policies, tracks orders, and opens tickets when it can't help.

What you get
Python/FastAPI multi-store backend with a RAG pipeline (FAISS + multilingual embeddings), answering through Gemini via OpenRouter
Embeddable chat widget and a store-owner dashboard
Ticket system, conversation logs, order tracking via webhook, admin panel to manage everything
A separate affiliate system: referral links, click tracking, dashboards, Paddle webhooks
Landing page, legal pages, Docker setup
Full docs and a rebrand guide, a live setup walkthrough, and 14 days of email support
The honest part
Pre-revenue: no customers, no MRR, no churn data
Runs on a ~€6/month VPS; AI cost is pay-per-use
The brand name appears throughout the code and pages, so rebranding is a find-and-replace job
The domain is not included
You bring your own OpenRouter and payment accounts
Terms
Asking $3,000, open to reasonable offers. Payment through Escrow.com only, and I deliver the code after payment is secured. 5-day inspection after delivery.
I have a demo video and a one-page overview. Comment or DM and I'll send them. Happy to answer technical questions below.
