How One Enterprise Turned Their QA test scripts into a 24/7 Product Training System

DemoPro transforms existing test scripts into interactive, multilingual walkthroughs with real-time AI guidance and support.

The Situation

The client is a US-based telecom enterprise running complex, multi-workflow software across multiple teams and regions.

The organization faced several challenges:

  • Every new customer cohort required live onboarding sessions with product specialists.

  • Product updates triggered repeated video re-recording, often taking 2–5 days per workflow.

  • Support teams handled recurring questions already covered in documentation.

  • Global users lacked on-demand, multilingual guidance across time zones.

The initiative: Replace manual demonstrations and reactive support with AI-driven walkthroughs and conversational assistance available around the clock.

What was breaking and What it was Costing

Complex enterprise applications require users to navigate multiple workflows, understand system behaviour, and troubleshoot unexpected situations. When guidance depends on specialists, onboarding slows down and support demand grows.

Key Challenges:
  • Trainer dependency: Onboarding relied on specialist availability, delaying access for distributed teams.
  • Outdated content: UI changes and new features made existing recordings obsolete, creating a continuous re-recording backlog.
  • Repetitive support: Users continued raising tickets for routine questions, even after completing training.
  • Limited in-context assistance: Users had no interactive way to resolve issues while working in the application.
  • Language barriers: Creating and maintaining separate training videos for global teams was costly.
  • Knowledge retention: Product expertise remained dependent on individuals rather than an accessible, maintainable system.

The client needed an AI product expert capable of guiding users, answering questions, and troubleshooting workflows without relying on constant human intervention.

The Insight That Changed Everything

The QA team already maintained detailed Robot Framework automation scripts documenting application screens, workflows, and user actions.

This content was regularly updated alongside the product but used primarily for testing.

TechTez recognised an opportunity: turn existing test scripts into reusable, continuously updated training content.

DemoPro was built around this principle, transforming QA automation into an interactive product learning and support experience.

The TechTez Approach

TechTez developed DemoPro, an AI-powered platform that converts existing automation scripts into narrated walkthroughs with visual guidance and an integrated, retrieval-augmented generation (RAG) assistant.

Four design principles shaped the solution:

  1. Reuse Existing Automation: DemoPro reads the QA team’s existing test suite, eliminating the need for a separate training content creation process. When workflows change, affected training components can be regenerated.
  2. Generate Contextual AI Narration: Claude analyses test steps and generates clear, conversational explanations of each action and its purpose.
  3. Synchronise Audio and Video: A custom Python library aligns narration with the corresponding on-screen actions, producing polished walkthroughs without manual post-production.
  4. Enable Interactive, On-Demand Support: Users can ask questions by voice or text while watching a demo. The RAG assistant retrieves relevant product documentation and delivers contextual answers with source citations and optional voice playback.

What Was Built

DemoPro integrates the following capabilities into an end-to-end generation pipeline:

  • AI Script Enhancement Engine: Generates narration, element highlights, and contextual guide callouts from test steps.
  • Automated Browser Execution: Playwright drives Chromium to execute workflows and record application interactions.
  • Speech Synthesis and Caching: Amazon Polly generates narration, while MD5-based caching reuses audio clips to reduce repeated synthesis costs.
  • Audio-Video Synchronisation: A custom Python library aligns narration with video timestamps.
  • Interactive Video Player: Chapter navigation lets users jump directly to relevant workflow steps.
  • RAG-Powered Q&A: AWS Bedrock and ChromaDB support semantic retrieval across product documentation, with cited answers and voice delivery.
  • Incremental Regeneration: Only components affected by product changes are regenerated, reducing unnecessary processing.
  • Multilingual Training: The same test suite can generate narrated demos in supported Amazon Polly languages.

How the platform works

  • Identify the automation scripts or workflows to demonstrate.
  • Analyse application flows using test scripts and documentation.
  • Select the workflows for training and Execute them automatically using browser automation.
  • Generate the video, narration, and on-screen highlights.
  • Publish the interactive demo with real-time AI assistance.

Platform Highlights:

  • Automated conversion of Robot Framework scripts into interactive training videos
  • AI-generated narration, visual highlights, and contextual guidance
  • In-video Q&A with voice interaction and source citations
  • Chapter-based navigation for faster access to specific workflows
  • Targeted regeneration to keep training content current
  • Multilingual output from a single test suite
  • Low marginal generation costs as the training library grows

Tech Stack

  • AI and Intelligence: Anthropic Claude, AWS Bedrock, Amazon Polly, ChromaDB, Amazon Bedrock Titan, GitHub Copilot
  • Automation and Video: Robot Framework, Playwright, Chromium, Custom Python Sync Library, FFmpeg
  • Platform and Storage: Angular, FastAPI, Python, AWS S3

Impact & Results​​

DemoPro enabled a shift from trainer-dependent onboarding to a self-service learning and support model.

The platform helped users understand workflows through guided demonstrations, resolve questions during product usage, and access consistent training across teams and regions.

By reducing dependence on repetitive knowledge-transfer sessions, it also allowed product and support specialists to focus on more complex issues.
