REZ - agentic customer service for businesses

Description and use

REZ automatically answers common customer questions using a business’s own website content and escalates unresolved queries to the owner, improving support efficiency.

Problem

Online merchants receive repetitive customer questions that are already answered on their website, leading to time‑consuming inbox management.

Outcome

REZ reduces repetitive support emails, provides instant answers with source citations, and escalates unresolved issues to the business owner, improving response time and freeing staff for complex tasks.

Workflow

• Paste website URL into REZ
• REZ crawls the site (respecting robots.txt) and renders JS pages with headless Chrome
• REZ extracts single‑topic answers using Gemini and stores them as Sanity documents with source URLs
• REZ builds a Sanity Context Knowledge Base from those documents
• REZ serves the knowledge base to the agent via the Context MCP endpoint
• Customers chat with the embedded widget; REZ queries the knowledge base and replies with concise answers and source citations
• If REZ cannot answer, it creates a ticket in Sanity and emails the business with the transcript and a drafted reply

Evidence

REZ reads your pages and learns your products, prices and policies.

Source

When REZ doesn't know something, it doesn't make it up. Refunds, complaints, anything it isn't sure about, it takes the customer's details and emails your team the whole conversation.

Source

Every answer keeps its source URL. When two pages disagree, the answer is flagged for the business to review.
