Client Overview

An education technology entrepreneur needed a scalable self-service reception platform for schools, with future applications across hospitals, hotels, malls, and other visitor-heavy environments.

The Challenge

The goal was to reduce repetitive front-desk work, overcome language barriers, and centralize visitor activity - without exposing users to unrestricted AI responses or unpredictable token-based costs.

Proposed Solution

Penaxis designed a controlled, school-safe reception ecosystem comprising:

  • Locked Android kiosk with voice, text, and touch interaction
  • Multilingual assistance across six manually selectable languages
  • School-approved knowledge base supporting up to 100 FAQs
  • Semantic question matching with confidence-based answer retrieval
  • Digital visitor sign-in, sign-out, and real-time on-site register
  • Two-way translation between reception staff and visitors
  • Customisable receptionist avatar, name, and school branding
  • Admin portal for FAQs, users, languages, visitors, and unanswered questions
  • Analytics for kiosk sessions, popular questions, language usage, and visitor activity

The configuration-driven architecture would let the same platform be adapted for additional schools and industries without rebuilding the core product. Phase 1 retrieves only school-approved answers - no GPT or other generative LLM sits in the live response path.
