"Aurora AI Call": Anyone Can Easily Design Advanced AI Calls with New AI-Powered Automation Features

Media4u Co., Ltd. (Minato-ku, Tokyo; President and CEO: Toru Iehata; hereinafter "Media4u"), a wholly owned subsidiary of Fabrica Holdings Co., Ltd., has announced a major update to its voice AI agent service "Aurora AI Call," introducing new functionality that simplifies the creation of prompts (instructions for AI) required to operate voice AI agents.

Background of the Update:

Recently, there has been growing interest in adopting AI for telephone response operations to improve efficiency and address labor shortages. However, many users face significant challenges when it comes to "writing effective prompts." Common issues include uncertainty about how to phrase instructions so the voice AI responds as desired, or finding that despite detailed configurations, response accuracy remains low, resulting in frequent call transfers back to human staff.

Believing that "AI should not be a complex system, but rather something intuitive and accessible—like training a new human employee," Media4u developed this new feature to lower barriers to adoption.

Key Update Features:

With this update, there is no longer any need to write technical terminology or complex rule sets. Users can now create AI prompts simply by giving natural language instructions such as, "Create a prompt for appointment booking. If there's a question about allergies, transfer the call," or by uploading existing manuals—just as one might hand over documentation to a new employee. Even users unfamiliar with IT systems can set up AI quickly and begin using it as a reliable partner on the same day.

"Prompt Auto-Generation" via Natural Language Instructions

By entering just a few lines of text, the AI interprets the user's intent, infers conditional logic and required questioning points, and automatically generates an optimized prompt. No expertise in prompt engineering is required.

"Document Upload" Support: Turn Existing Files into Working Prompts

Users can upload existing documents such as response manuals or FAQ sheets, and the AI will analyze the content and generate accurate response prompts. Leveraging existing text assets significantly reduces time and effort during implementation.

Flexible Additions and Edits: Continuously Improve in Operation

Automatically generated prompts can be freely edited afterward. On-site staff can directly modify base prompts without relying on external vendors, enabling rapid, ongoing improvements.

Use Case Examples:

Appointment Booking and Changes for Restaurants and Clinics

Input example: "Create a prompt for appointment booking. Check availability and only transfer to staff (03-XXXX-XXXX) if questions about allergies or medical conditions arise."

Even without technical knowledge, users can instantly generate a prompt that automates gathering information such as date, time, and number of people, and suggests available slots. Only exceptional cases or those requiring expert responses are escalated to human staff, allowing on-site employees to focus on core tasks and customer service.

Handling FAQs for E-commerce and Online Shopping Sites

Input example: Upload your company's "Return and Exchange Manual.pdf" and "Frequently Asked Questions.csv," then instruct: "Create an AI that answers customer inquiries based on these documents."

Eliminates the need to manually write complex conditional prompts. Once documents are uploaded, the AI automatically provides accurate responses regarding shipping fees, delivery status, return deadlines, etc., helping reduce call volumes at contact centers.

After-Hours and Holiday Emergency Triage for Property Management and Infrastructure Companies

Input example: "Create a prompt for handling after-hours tenant emergencies. Transfer calls about water leaks or lost keys to emergency responders; for all other issues, inform callers that support will be provided on the next business day."

Enables rapid deployment of a system that uses AI to assess the urgency of incidents during unstaffed hours. Reduces both workload and costs for personnel on call while ensuring prompt initial responses to customers.
