Copilot & AI in Power Platform

Copilot helps you build apps, automate processes, and create websites just by describing what you want.

What does Copilot do in Power Platform?

☕ Simple explanation

Copilot is like having a helpful colleague sitting next to you while you build.

You say, “I need an app that tracks customer complaints.” Copilot creates the table, builds the screens, and wires up the logic. You tweak what it made, and you are done.

You do not need to know how to design databases or drag controls onto a screen. You describe what you want in plain English, and Copilot does the heavy lifting. You stay in control — Copilot suggests, you decide.

Copilot is Microsoft’s generative AI assistant embedded across the entire Power Platform. It uses large language models (LLMs) to translate natural language descriptions into working apps, flows, tables, pages, and formulas.

Copilot appears in Power Apps (app generation, formula writing, UI editing), Power Automate (flow creation, action configuration), Power Pages (page layout generation, content drafting), and Dataverse (table creation, column suggestions). It also powers Copilot Studio, the dedicated platform for building custom copilots and chatbots.

For the PL-900 exam, you need to know where Copilot appears, what it can do, and how Copilot Studio differs from the built-in Copilot features.

Copilot across Power Platform

Copilot shows up everywhere. Here is where each character uses it:

ServiceWhat Copilot DoesExample
Power AppsGenerates entire apps from a description, suggests formulas, edits screens via chatPriya says “Create a campaign expense tracker” and gets a working app with a table and three screens
Power AutomateBuilds flows from natural language, suggests next actions, explains existing flowsCarlos says “When a leave request is approved, send a Teams message to HR” and the flow is built
Power PagesGenerates page layouts, writes content, creates formsTom describes “A property listing page with filters and a contact form” and gets a draft layout
DataverseCreates tables and columns from a descriptionAisha says “I need a table to track fleet vehicles with registration, make, model, and service date” and the table is ready
💡 Copilot writes Power FX too

Inside Power Apps, you can ask Copilot to write Power FX formulas. Instead of figuring out the syntax for a complex filter, you type “Show only records where status is Active and created this month” and Copilot writes the formula for you.

This is a big deal for the exam — Copilot lowers the barrier even further by removing the need to learn formula syntax upfront.

Copilot in Power Platform vs Copilot Studio

This is a critical distinction for the exam. They sound similar but serve different purposes:

Copilot in Power Platform vs Copilot Studio
AspectCopilot in Power PlatformCopilot Studio
What it isAI assistant built into the maker toolsA separate product for building custom copilots
Who uses itApp makers and flow buildersAnyone who wants to create a chatbot or copilot agent
What it doesHelps YOU build apps, flows, and pages fasterBuilds chatbots that YOUR USERS interact with
Where it livesInside Power Apps, Power Automate, Power PagesIts own studio at copilotstudio.microsoft.com
ExamplePriya asks Copilot to add a chart to her appPriya builds a chatbot that answers campaign FAQs for her team
OutputA better app, flow, or pageA deployed copilot or chatbot

The short version: Copilot in Power Platform helps makers build. Copilot Studio lets makers build copilots for end users.

What is Copilot Studio?

Copilot Studio is Microsoft’s low-code platform for building custom copilots and chatbots. You do not need to write code — you create topics, define conversation paths, and connect knowledge sources.

Key capabilities:

  • Topics — Define what your copilot can talk about. Each topic has trigger phrases and a conversation flow.
  • Generative answers — Connect your copilot to documents, websites, or Dataverse tables. It uses AI to generate answers from your content — no need to author every response manually.
  • Actions — Your copilot can call Power Automate flows to do things like create records, send emails, or look up data.
  • Channels — Publish your copilot to Teams, websites, Facebook, or any channel supported by the Bot Framework.

Carlos built a copilot in Copilot Studio for Greenleaf Health employees. Staff ask questions like “How many leave days do I have left?” and the copilot calls a Power Automate flow that checks Dataverse and returns the answer.

ℹ️ Generative answers: the game-changer

Before generative answers, building a chatbot meant manually creating a response for every possible question. Miss a topic? The bot says “I don’t understand.”

With generative answers, you point the copilot at a knowledge source — a SharePoint site, a website URL, or uploaded documents — and it generates natural-sounding answers from that content. This dramatically reduces the effort needed to build a useful copilot.

The exam will test that you know generative answers exist and that they pull from connected knowledge sources.

AI Builder: pre-built AI models

Beyond Copilot, Power Platform includes AI Builder — a set of pre-built and custom AI models you can use inside apps and flows without any machine learning expertise.

AI ModelWhat It DoesExample
Document processingExtracts data from invoices, receipts, formsCarlos extracts leave request data from scanned PDF forms
Text recognition (OCR)Reads text from imagesAisha scans shipping labels to auto-populate tracking records
Sentiment analysisDetects positive, negative, or neutral tonePriya analyses customer feedback emails for sentiment trends
Object detectionIdentifies objects in imagesTom detects property features (pool, garage) in listing photos
PredictionPredicts outcomes based on historical dataCarlos predicts which new hires are likely to need extended onboarding
ℹ️ Exam tip: AI Builder vs Copilot

Copilot helps makers build faster — it generates apps, flows, pages, and formulas from natural language.

AI Builder adds intelligence to finished apps and flows — it processes documents, detects sentiment, reads images, and makes predictions at runtime.

If the exam asks about generating apps, it is Copilot. If it asks about processing invoices or detecting sentiment, it is AI Builder.
