AI Customer-Support Assistant that auto-maps any business site, answers WhatsApp in real time, and lets you earn or save thousands by replacing pricey SaaS chat tools.

What the workflow doesLive “AI employee” - the bot crawls pages on demand (products, policies, FAQs) so you never upload documents or fine-tune a model.

No-code setup - Drop in API keys, paste your domain, publish the webhook, ready in ~15 min.

Chat memory - each conversation turn is written to Supabase/Postgres and automatically replayed into the next prompt, letting the assistant remember context so follow-up questions feel natural and coherent even across long sessions.

WhatsApp ready - Free-form replies inside the 24-hour service window, automatically switches to a template when required (recommended by Meta).

Monetization ideas

- Replace costly SaaS seats. Deploy the bot on your own server and stop paying $300, $500 every month for third-party “AI support” platforms.

- Sell it as a service. Spin up a branded instance for local shops, clinics, or e-commerce stores and charge each client $300, $500 per month, setup time is under 15 minutes.

- Upsell premium coverage (24/7 human hand-off) once the bot handles routine questions.

- Embed product links in answers and earn affiliate or upsell revenue automatically.

Spin it up, connect a domain and a phone number, and you, or your customers, get enterprise-grade support without code, training, or ongoing licence fees.
