What it does

GenU (Generative AI Use Cases) is a TypeScript/React application deployed via AWS CDK. It bundles twelve pre-built AI workflows—chat, summarization, translation, image and video generation, voice chat, meeting minutes from audio, diagram generation, and more—into a single web interface backed by Amazon Bedrock. The stack includes RAG options through Kendra or Knowledge Base, support for custom Bedrock Agents and Flows, and an enterprise-friendly layer of SAML authentication, metadata filtering, and security controls.

The interesting bit

The “Use Case Builder” lets non-developers create new AI workflows by writing prompt templates in natural language; GenU auto-generates the UI forms and sharing infrastructure. It is essentially a low-code prompt-to-product pipeline that tries to stop every department from building their own shadow-AI chatbot.

Key highlights

• Twelve built-in use cases ranging from contract Q&A to real-time voice chat with interruption support
• RAG via Amazon Kendra or Knowledge Base, with chunking strategies, query decomposition, reranking, and metadata filters
• Import and expose custom Bedrock Agents, AgentCore runtimes, and Bedrock Flows to the organization
• MCP server support for connecting to external data sources and services outside AWS
• SAML authentication and granular security options for enterprise deployment
• Multi-language support (English, Japanese, Korean) since v4

Caveats

• Deployment requires enabling specific Bedrock model access in the correct region before CDK will succeed
• The README warns about merge conflicts if you fork and customize core code
• Custom use cases exported as JSON could leak confidential prompts if shared carelessly

Verdict

Worth evaluating if you are an AWS shop that needs a governed, shareable AI playground for business users. Skip it if you are not committed to the Bedrock ecosystem or need fine-grained control over model hosting outside AWS.
