Rollstack vs Microsoft Copilot in PowerPoint:Drafting help vs a deck tied to your data

Where the numbers come from

Copilot drafts from a prompt or from files in OneDrive and SharePoint. Its interactive slides, rolling out since October 2026, can build a dashboard from a snapshot of an Excel workbook. They don't stay connected to the workbook, and opening the file resets them.

Rollstack connects directly to the source: Excel and Power BI, plus warehouses, other BI tools, Google Sheets, CRMs, PDFs and any source with an API. Every chart, table and number on a slide is the result of a query, so the deck shows exactly what the source says.

Checking the numbers

Copilot grounds its drafts in your files, and Microsoft asks you to review Copilot's output before you present or share it. Nothing on the slide shows a reviewer where each figure came from.

In Rollstack, every figure on a slide can be traced back to the raw data and each transformation applied to it. Reviewers can check numbers without rebuilding anything.

When Rollstack's AI makes changes, you can review them before the deck goes out: the original and the edited slide side by side, with all changes highlighted.

Your template

Here Copilot is strong. It uses your organization's template and Brand Kit, and with Strict brand adherence turned on, it sticks to your approved layouts.

Rollstack keeps your template as it is too, in PowerPoint and Google Slides. Upload your PowerPoint file, or import it from Google Slides or OneDrive, and it becomes a reusable template with your masters, placeholders, fonts and footer intact. Pick a dashboard, table or sheet as the source, and Rollstack builds the deck in that template, with native charts connected directly to your data.

Next month

Copilot Cowork can run a prompt on a schedule, such as a weekly status report every Friday, and edit a PowerPoint file in OneDrive or SharePoint. Each run regenerates the content with AI, and Cowork is billed by usage on top of a Premium license.

In Rollstack, next month is a refresh of the same deck. Only the numbers and charts change; your commentary, layout and slide order stay as you left them.

What about the Power BI add-in?

Microsoft's Power BI add-in for PowerPoint embeds live report pages and visuals in slides, and it respects row-level security. Every viewer needs an active Power BI account and access to the data, and Microsoft doesn't support sharing with other companies.

That rules it out for client-facing decks. Rollstack refreshes Power BI content into a normal PowerPoint or Google Slides file, so a client, partner or board member opens it without a Power BI license or login.

One template, every audience

Cowork can produce several files in one task, but Copilot has no way to turn one template into a version per audience.

Rollstack Bursts turn one template into a version per region, sales channel, team, product line or client, each filtered to its own data. A change to the template reaches every version on the next run.

Finance teams already run their reporting this way with Rollstack:

• SoFi updates 400+ slides across 30+ decks every month.
• Tripadvisor's finance analysts reclaimed 4,216 hours in Q1 2026.
• Octopus Energy automated its credit performance review cycle.

Permissions, security and your LLM

Copilot inherits Microsoft 365 compliance, including GDPR, ISO 27001, ISO 42001, HIPAA and the EU Data Boundary, and it only uses content the builder can view. When editing in PowerPoint, you can choose between OpenAI and Claude models; Claude is on by default for most commercial customers outside the EU, EFTA and UK. Bringing your own model is for custom agents only.

Rollstack matches these, and goes further in three places that matter to regulated and data-heavy teams:

1. Follows the roles and permissions in your BI tools and warehouse, including row-level security, so each version contains only its audience's data.
2. Logs every update and keeps every deck as it was sent, so you can show what a stakeholder saw and when.
3. Lets you choose the LLM, whether that's Claude Opus 5.5, GPT 6.1 Sol or your own Azure AI Foundry, OpenAI, Anthropic, Amazon Bedrock or Google Vertex AI account on the Enterprise plan. Rollstack's model providers don't train on your data.

Using both

Many teams draft and polish with Copilot, then publish and refresh in Rollstack. Copilot Studio agents can call tools through MCP, so an agent can ask Rollstack for a deck whose numbers come from your sources.

Here's a common scenario: your FP&A team sends a 25-slide pack to the leadership team after every close. The numbers come from an Excel model and a Power BI report.

With Copilot, you can draft the narrative slides, keep them on brand, and build an interactive slide from a snapshot of the Excel model. Each month the numbers still have to be brought in again, by hand or with a new Cowork run, and someone checks every one before the pack goes out.

With Rollstack, the pack is connected once to the Excel model and the Power BI report. After close, it refreshes. Your analysts review what changed, write the commentary and send. If each business unit, region or product line needs its own pack, a Burst creates one for each.
