Copilot Studio vs Power Virtual Agents is a common question for teams who use Microsoft’s tools to build chatbots and internal support agents. Copilot Studio, which Microsoft replaced Power Virtual Agents with, is more than just a name change. It signals a change from basic chatbots to AI agents that can reason, gather information from multiple systems, and assist with daily tasks.
Power Virtual Agents helped others in creating bots without knowing how to write code. For routine tasks and structured questions, it performed well. Building on that framework, Copilot Studio includes modern AI capabilities like generative responses and improved Microsoft 365 integration. The end product is a tool that supports Microsoft’s transition to a single Copilot ecosystem and can handle a greater variety of use cases.
This article explains Power Virtual Agents, Copilot Studio, the differences between the two tools, and the real-world effects of the change.
What are Power Virtual Agents?
Power Virtual Agents was Microsoft’s tool for chatbots builders. A chatbot is a program that can talk to people and answer questions. Power Virtual Agents let you build these bots without writing code. Microsoft describes it as a “no-code graphical interface” for creating chatbots.
It worked with topics.
A topic was a question-and-answer path. For example, the topic is “Reset my password.” And the bot knew how to guide you through that one task.
It handled simple, predictable questions. It worked best when the question was clear and expected, like: “How do I request time off?”, “Where is my order?”, “What are your working hours?”. If the user asked something outside the expected topics, the bot often got stuck.
It could do small tasks
Power Virtual Agents connected to Power Automate when the bot needed to fetch data or complete an action, like creating a ticket or pulling a record.
It could be used in Teams or on a website
You could publish your bot to Microsoft Teams, a website, or other channels.
What it was good at
- Simple questions
- Repetitive support tasks
- Predictable conversations
What it wasn’t good at
- Open-ended questions
- Conversations with many twists
- Complex reasoning
- Handling unexpected user input
Because the bot followed strict paths, conversations often felt stiff or limited. Power Virtual Agents was a tool that let people build simple chatbots for routine questions. It worked well for clear tasks but struggled with flexible, natural conversations.

What Is Copilot Studio?
Copilot Studio is Microsoft’s next-generation chatbot builder, designed for more intelligent and flexible AI agents. If Power Virtual Agents helped you build simple chatbots, Copilot Studio helps you build smarter AI agents that can understand more, connect to more systems, and handle more complex tasks.
Think of it this way, Power Virtual Agents is for simple chatbots while Copilot Studio still lets you build bots without writing code, but it adds modern AI features that make the bots much more capable. You can learn more about writing Copilot prompts here.
Here’s what Copilot Studio does in a simple way:
It can understand open-ended questions
Power Virtual Agents needed you to define every question. Copilot Studio can understand questions even if you didn’t write them ahead of time. For example, a user types “How do I claim travel expenses for an overseas trip?” Copilot Studio can read your documents, find the answer, and explain it.
It uses generative AI (like GPT)
This is the biggest upgrade. Copilot Studio can read information, summarize them then generate the responses, explain the rules and work with business data. This makes conversations feel more natural.
It can connect to many systems directly
Copilot Studio can link to:
- Microsoft 365
- SharePoint
- Dataverse
- Dynamics 365
- APIs
- Power Automate
- External databases
This means the bot can do real tasks, like:
- check an order
- update a CRM record
- create a support ticket
- pull HR data
- schedule a meeting
It can extend Microsoft Copilot
This is new. You can use Copilot Studio to build custom features that appear inside Microsoft 365 Copilot. So your own bot becomes part of the Microsoft Copilot experience your company uses. For example, You can build a “Finance Copilot” that reads company politics, explains them and answers finance questions inside Teams or Outlook. Power Virtual Agents could not do this.
It handles complex conversations better
Copilot Studio can keep track of context. For example, the user would say “I need help with my insurance.” And the bot would reply saying, “Home, car, or health insurance?” and the user would reply with, “Car.” Bot knows the user means car insurance without resetting the conversation.
It still supports the basics
Everything that Power Virtual Agents did, Teams bots, web bots, simple flows, is still included. Copilot Studio just adds much more on top of it. Now that we’ve looked at what each tool can do, let’s look more closely at Copilot Studio vs Power Virtual Agents and how their capabilities compare in practice.
Copilot Studio vs Power Virtual Agents
Answers questions you didn’t script
Copilot Studio uses generative AI to answer questions by pulling information from your documents, websites, or databases, even if you didn’t predefine the question or response. PVA relied on manual scripting.
Plans and executes actions on its own
Copilot Studio can figure out what tools or workflows it needs and chain them together using AI. For example, if a user says, “Update my address and send me a confirmation,” the AI can find the right API and email flow and do both automatically.
Works with data and models, not just scripts
You can connect Copilot Studio to internal databases, SharePoint, and even your own GPT models. The AI can choose the right model or data source for each question without manual switching.
Integrated with Microsoft 365 Copilot
Bots built in Copilot Studio can show up directly in Microsoft Teams, Outlook, or the Copilot Chat panel, not just on websites or in chat widgets. This puts your custom assistant where users already work.
Actions, not just answers
While PVA could only give responses or trigger flows manually, Copilot Studio agents can complete full workflows, like scheduling meetings, retrieving files, or updating CRM, through a single user request.
Smarter governance and security
Copilot Studio adds role-based access, audit logging, and safer plugin management. This helps organizations scale AI assistants without losing control.
How Microsoft Shifted From Chatbots to AI Agents
The old bots followed rules — the new ones make decisions
Power Virtual Agents used structured dialogs. Copilot Studio bots use AI models that can understand intent, ask clarifying questions, and decide how to help based on real-world input.
From answering to executing
PVA could answer questions. Copilot Studio can do things like update a record, send an email, generate a document, or kick off a workflow all from one user input.
Not just reactive — proactive
The new AI agents can respond to events (like a system alert) and take action without waiting for the user to say something. This opens up use cases like automated onboarding or issue resolution.

One assistant, many places
You don’t just build a chatbot for a web page. You build an AI assistant that can live in Teams, Office apps, SharePoint, or your internal portals and act consistently across all of them.
Real business value, not just support automation
The goal isn’t just to reduce tickets anymore. Copilot Studio agents can help sales teams close deals, help HR with employee requests, or assist finance with reporting, they’re treated like digital coworkers.
AI agents are the new interface for getting work done
This shift moves away from search boxes and buttons. Users just ask for what they need and the agent figures out how to do it. Microsoft now sees Copilot Studio as a central way to build these workplace copilots.
Final Thoughts
When comparing Copilot Studio vs Power Virtual Agents, the difference comes down to flexibility, intelligence, and usefulness. Copilot Studio is a smarter tool and it’s a shift in how businesses build AI-powered assistants.
The shift reflects a broader trend, chatbots are no longer enough. People want assistants that can answer questions, take action, and work across tools they already use. Copilot Studio meets that need by combining generative AI with task automation and enterprise-level integration. Specially, with being able to integrate Copilot with ChatGPT, there isn’t anything that you can’t do.
For organizations, this means you’re not building scripts anymore but you’re building AI agents that can help people do real work. Whether that’s in Teams, Outlook, or on your website, the assistant is now smarter, faster, and more useful than anything Power Virtual Agents could offer.
