Power BI Copilot: AI Summaries, Narratives and Responsible Review

Start with the reporting problem

A generated summary can save writing time, but its usefulness depends on the quality of the selected evidence and the accuracy of its comparisons. Review the numbers, periods, filters and explanatory claims separately. This guide uses a small admissions example to show how a fluent paragraph can still describe the wrong business result.

Core concepts to learn

Build a practice scenario

1. Create the fictional admissions table below and calculate the expected growth and target achievement.
2. Name the visuals clearly and choose the report content the narrative should summarize.
3. Generate or manually draft a short summary, then verify every numerical statement and comparison.
4. Change the course filter, refresh the narrative where applicable and document whether its scope matches the new view.

Use sample, authorised or fictional data. Do not publish credentials, business data, account numbers or customer information in a portfolio. If a task has financial, security or production impact, include a review or approval step before any change.

What good work looks like

Check which Copilot experience you are using

Power BI has several Copilot experiences, and their scope matters. Microsoft’s documentation checked on 4 October 2026 describes the report Copilot pane as generally available, while the standalone and app-scoped agent experiences remain in preview. A report narrative visual has a narrower task than a cross-item assistant: it summarizes the selected report content. Identify the surface before copying instructions from another workflow.

The current general requirements include paid Fabric capacity at F2 or above, or Power BI Premium capacity at P1 or above, plus supported region and administrative settings. A Pro or Premium Per User license by itself is insufficient, and trial capacity does not satisfy the paid-capacity requirement. A visible Copilot button therefore does not prove that a learner’s workspace can use it.

If access fails, record the workspace, capacity assignment, account permissions and exact disabled message. Ask the administrator to check the applicable settings and region. Rewriting the prompt cannot resolve a capacity or authorization problem. Avoid assuming that a paid individual license includes every organizational AI experience.

Prepare a model that explains the business language

Before requesting a summary, agree the definitions of revenue, enrolment, active student and completed course. An admissions count can mean applications submitted, fees paid or students who attended their first class. Create explicit measures and meaningful field descriptions so a reader can determine which event the report actually counts. A polished paragraph cannot reconcile inconsistent definitions hidden in different visuals.

Review table names, relationships and exposed fields as part of model preparation. Microsoft recommends preparing semantic models for AI so Copilot has clearer business context. Keep a short glossary beside the exercise, then ask the same question using everyday wording and the formal measure name. Record any material difference for model review rather than assuming the longer answer is more accurate.

An original summary review exercise

Use fictional monthly admissions data: 80 paid enrolments in August and 100 in September. The increase is 20 enrolments, or 25% relative to August. Suppose the September target was 120. September achieved approximately 83.33% of that target and remained 20 enrolments below it. These statements can all be true at the same time.

Ask for a short summary that states the period, paid-enrolment measure, previous-month comparison and target comparison. Specify that explanations for the movement should be labelled as hypotheses unless evidence is present. Then check every generated number against a table showing August, September and target. Preserve the original prompt and filters alongside your review.

A sentence saying admissions improved by 20% is wrong for this dataset: it confuses the absolute increase with the percentage change. A sentence saying the team exceeded expectations is also unsupported when the stated target was missed. Correct the wording by citing the relevant measure and denominator. Do not merely ask the assistant to sound more confident.

Now add a course filter that changes September paid enrolments to 24 and August to 20. The filtered growth is 20%, even though the all-course growth was 25%. This deliberately creates a useful test: can the reviewer identify which scope the narrative describes? Record the chosen course and comparison dates in the final text.

Refresh the narrative after changing the report

Microsoft’s narrative documentation says the visual summarizes information from the selected report visuals, not an unrestricted scan of every underlying model record. Clear titles and axes matter. A hidden detail that was never part of the selected content should not be treated as independently reviewed evidence.

The narrative does not automatically update with every filter change; use its refresh control to obtain a summary for the changed slicers and filters. After refreshing, inspect the cited visual references and compare the output again. Copying last month’s narrative into a new presentation without this check can preserve perfectly fluent but stale statements.

In the exercise, save two versions of the review log: the all-course view and the filtered course view. Each should show the prompt, filter scope, refresh time, reported result and reviewer decision. This is a much stronger portfolio example than a screenshot of an unverified paragraph.

Separate observations from explanations

A report can show that admissions rose while enquiries also increased. That alone does not establish why the rise occurred. A campaign, revised pricing, changed recording process or seasonal timing might be relevant, but each needs evidence. Label an explanation as a question for follow-up when the model does not contain the needed facts.

Review permissions before sharing the result. A copied paragraph or exported slide becomes a separate artefact; the recipient may not have the same report access as its author. Use fictional data for public practice, and keep internal review material in its intended audience. Include the reporting cutoff so readers know which events could be missing.

Common review questions

Can I trust a statement because it has a visual reference? Treat the reference as a route to verification. Check the visual, denominator, date window and filter context yourself. A supported number can still be described with the wrong comparison or an unjustified causal claim.

What if Copilot is unavailable in my practice account? You can still build the validation table, calculate the expected statements and review a manually written summary. The reasoning exercise remains useful; do not claim hands-on Copilot execution without access.

When is a summary ready? It is ready when its key claims match the selected evidence, assumptions are explicit and the intended reader can distinguish a measured result from a proposed explanation.
