Real-World Use Cases and Workflows

Microsoft AI chat is no longer just a chatbot—it’s a workflow enabler. Here are practical examples across domains:

🏢 Enterprise: Automating Contract Review with Copilot in Word

1. Upload a contract to OneDrive for Business.
2. Open the document in Microsoft Word.
3. Click the Copilot sidebar and prompt:

"Summarize the key obligations in this contract and flag any clauses with high liability risk."

4. Copilot:

• Extracts obligations (e.g., payment terms, delivery dates).
• Flags clauses with phrases like "indemnify," "consequential damages."
• Generates a structured risk assessment in a side panel.

Pro Tip: Use Microsoft Purview to apply sensitivity labels before processing sensitive documents.

🏠 Consumer: Home Automation with Windows Copilot

"Hey Windows Copilot, turn on my smart lights to 60% brightness and play my focus playlist."

• Windows Copilot integrates with IoT devices via Home Assistant or SmartThings.
• Supports natural language automation using Power Automate Desktop or AutoHotkey scripts.
• Can trigger macros in Excel, open apps, or launch PowerToys tools.

🛠️ Developer: Building a Customer Support AI Agent with Semantic Kernel

1. Create a Semantic Kernel project:

   dotnet new console -n SupportAgent
   cd SupportAgent
   dotnet add package Microsoft.SemanticKernel

2. Add the Email Plugin and Knowledge Base Plugin:

   kernel.ImportPluginFromPromptDirectory("plugins/Email");
   kernel.ImportPluginFromType<KnowledgeBasePlugin>();

3. Define a chat loop:

   var result = await kernel.InvokePromptAsync(
       "Answer this customer question using the knowledge base: {{ $input }}",
       new() { ["input"] = userQuestion }
   );
   Console.WriteLine(result);

4. Deploy to Azure Container Apps for scalability.

Best Practice: Use Azure Monitor to track latency, token usage, and user feedback.

AI Assistants: From Chatbots to Intelligent Agents

Microsoft’s vision for AI in 2026 is not just chat—it’s autonomous agents that plan, act, and collaborate.

Key Features of Modern AI Assistants:

• Memory: Long-term context across sessions (via Microsoft Graph and Azure Cosmos DB).
• Planning: Multi-step workflows using Semantic Kernel’s planner.
• Tool Use: Integration with APIs, databases, and external tools (e.g., Jira, Salesforce).
• Collaboration: Multi-user sessions in Teams or SharePoint.

Example: Meeting Assistant in Teams

• Joins a Teams meeting via Copilot for Meetings.
• Takes real-time notes.
• After the meeting:
• Generates a meeting summary.
• Creates follow-up tasks in Planner.
• Drafts an email to stakeholders: > "Hi team, here are the action items from today’s sync: [list]. Please update status by EOD Friday."

Security Note: Meeting data is processed within Microsoft 365 compliance boundaries—no data leaves the tenant.

Advanced Configuration: Fine-Tuning and Customization

To get more control over AI behavior, you’ll need to customize models and workflows.

Fine-Tuning Models with Azure AI Foundry

1. Upload your dataset to Azure Blob Storage.
2. Use Azure AI Foundry Studio to:

• Select a base model (e.g., mistral-large, phi-3.5).
• Upload training data in JSONL format: json {"prompt": "What is the return policy?", "response": "30 days, full refund."}
• Start fine-tuning with a few clicks.
• Deploy the model as an endpoint with a REST API.

Using Semantic Kernel for Agent Orchestration

Build agents that can:

• Search internal wikis.
• Generate code in multiple languages.
• Call external APIs (e.g., weather, stock prices).
• Use vector memory for semantic search.

Example: A Research Assistant Agent

from semantic_kernel.agents import ChatCompletionAgent
from semantic_kernel.connectors.ai.open_ai import AzureChatCompletion

agent = ChatCompletionAgent(
    service=AzureChatCompletion(
        deployment_name="gpt-4-2026",
        endpoint="https://your-ai-foundry.azurewebsites.net"
    ),
    name="ResearchBot",
    instructions="You are a research assistant. Use the knowledge base plugin to answer questions. Cite sources."
)

result = await agent.invoke("What are the latest trends in quantum computing?")
print(result)
