Questions & Answers

As answered by people managing RuleInside and Vapi.

What makes your product unique?

RuleInside's answer

RuleInside is a team of AI voice agents for WordPress and WooCommerce stores, built and run for the store owner. Each agent owns one job: answering questions, closing the sale, recovering carts, checking in after delivery or bringing back past buyers. They answer by phone, website chat and WhatsApp, in the shopper's language. Our own WordPress plugin connects them to the store's live prices, stock and orders, so an agent can look up an order in the middle of a call. Anything that moves money stays with a person: the agent files a refund request, and the owner decides in the RuleInside portal.

Why should a person choose your product over its competitors?

RuleInside's answer

Because the store owner does not have to become an engineer. Voice AI platforms sell building blocks to developers, and several AI phone agents built for online stores work with Shopify only. With RuleInside, we install the plugin, build the agents, test them and keep tuning them. The owner sees every call, recording and transcript in the portal. Before every outbound call, the agent checks opt-outs, do-not-call lists and calling hours, and every agent says it is an AI. Store data is kept in an EU database in Ireland, and each store's data stays separate.

How would you describe the primary audience of your product?

RuleInside's answer

Owners of established WordPress and WooCommerce stores who still answer customers themselves, or who are thinking about hiring someone to do it. They want every call, chat and WhatsApp message answered at any hour, and carts and past buyers followed up, without running the software themselves. RuleInside is not for brand-new stores yet.

What's the story behind your product?

RuleInside's answer

In 2018 Stefano Bertoli founded EarthMeals, a plant-based ready-meals ecommerce brand covered by Wired and Vanity Fair Italia. Going back through its numbers, he found months of unanswered questions and abandoned carts on ordinary nights. He then worked as a consultant for more than 30 businesses in Italy, Spain and the US, and saw the same leak in every one: calls nobody answered at 10pm, carts nobody followed up, past customers nobody contacted again. AI voice agents could now answer every call at any hour, but the tools that build them are made for developers. So he built RuleInside, which builds and runs the agents for the store owner.

Which are the primary technologies used for building your product?

RuleInside's answer

  • ElevenLabs Conversational AI: the agents' voices and conversations, phone calls, batch calling and WhatsApp
  • OpenAI: GPT-4.1 mini, the default model for new agents, and embeddings for product search
  • Supabase: the Postgres database (hosted in Ireland, with row-level security), Edge Functions, pgvector and scheduled jobs
  • Next.js on Vercel: the RuleInside portal, built on MakerKit
  • A WordPress plugin for WooCommerce, which connects each store
  • Stripe (usage billing), Twilio (phone numbers), Cal.com (bookings), Resend (email) and Better Stack (error alerts)
