How It Works

Tested result

In our own test, the same Copilot prompt on our original template and on the rebuilt one: 37 loose text boxes down to 0, every slide on a named layout.

Copilot copies what it is shown

Copilot learns from the sample slides, placeholders and theme definitions in your template, and it copies its examples closely, down to their density. If your example slides are drawn freehand from loose text boxes, the decks it builds will be too. If your layouts have numbers for names, Copilot has little to go on when it picks one. And with strict brand adherence on, Copilot will not add or remove placeholders or invent new layouts, so if there is no chart slot, there is nowhere for a chart to go.

What we have tested, and what we found

We tested the whole setup end to end in Microsoft 365: a Brand Kit built for a client’s brand, with strict brand adherence on, and separate tests on our own template. These are results from our tests, not guarantees.

  • PowerPoint: Copilot built a six-slide deck using only the template’s own layouts, with no fonts or colors typed in and the logo on every slide.
  • Charts: On our own template, Copilot built a real, editable column chart in the brand’s approved chart colors, on a template layout. One test.
  • Structure: On our own template, the same prompt produced 0 loose text boxes, 0 off-theme colors and 0 fonts set by hand, with every slide on a named layout.
Three example data slides: an accounts dashboard, a campaign results bar chart, and pipeline by industry.
Example slides from a brand template we designed.

Where the limits are

  • Icons: The Brand Kit stores icons, but in our testing Copilot placed none on slides.
  • Photos: With no approved photos in the kit, Copilot used its own stock images. Supply your approved photos.
  • Word: Copilot in Word has no brand selection. We provide a Word template in your brand, which works when opened directly.
  • Excel: The Excel template holds your logo, header, printing setup and chart colors, but Copilot restyles tables it creates.
  • Fonts: Brand fonts are replaced unless your IT team deploys them organization-wide.
  • Results vary: the same prompt can come out differently from run to run.
  • Facts: Copilot can invent plausible numbers, dates, job titles and contact details. A person checks every fact before a deck goes out.

What a template audit looks like

We audited our own brand template first. Here is what we found, why each finding matters to Copilot, and what the fix achieved.

The template: 187 slides, 75 layouts, 94 MB, a well-designed brand system in three backgrounds.

75 layouts

50 after the rebuild, each named for its purpose

1,174

loose text boxes on the example slides, against 697 placeholders

87.5%

37

slides whose speaker notes said only “done”

What was already right

  • The theme was sound: the brand colors sat in real theme slots, and the brand fonts were set as the theme fonts.
  • The system was consistent: every content layout existed in all three backgrounds, each with title, body, footer and slide-number placeholders.
  • There was plenty to teach from: about 165 designed slides.

What to fix, in priority order

PriorityFindingWhy it matters for Copilot
Fix first75 layouts, 45 of them near-identical covers and dividers named like “21_title-card-2”; 22 used by no slideCopilot picks layouts partly by name. A number tells it nothing, and 45 cover variants dilute every choice.
Fix firstNo layout built for a purpose: no picture, chart or table slot, no columns, no team or process structureWith strict brand adherence on, Copilot “won’t add or remove placeholders or invent new layouts” (Microsoft). It can only fill the slots the layouts give it.

What the fix achieved

We gave Copilot the same prompt against the original template and against the rebuilt one, each loaded in a Brand Kit with strict brand adherence on:

Original templateRebuilt template
Loose text boxes on the 7 slides370
Layouts Copilot could choose from75, mostly unnamed50, each named for its purpose
A stock person placed beside a presenter’s nameyesno
A chart requested (a separate test on the rebuilt template)—a real, editable chart in the brand’s chart colors

One test, on our own template. We can’t promise what a generative tool will produce; we can show what our work changed, and we test again every quarter. (How quarterly oversight works.)

Questions you may have

Will every deck Copilot builds be on brand?

No one can promise that about a generative tool, and we do not. We commit to conformance with Microsoft’s published guidance, testing with real prompts against your own template, and correcting what drifts.

Why do example slides matter so much?

Copilot learns from the sample slides in your template and copies them closely. Filler text, drawn charts or slides built from loose text boxes get copied too. Realistic, varied examples on the right layouts are what teach it your visual language.

Do we need new layouts, or just a cleanup?

The audit tells you. Copilot can only fill the slots your layouts give it, so if your template has no chart, table, picture or column layouts, those need to be built. If they exist, they may only need naming and tidying.

How do you test the result?

With a fixed set of prompts, run against your original template and the rebuilt one. Each output is scored for how much human work it still needs, and every failure is traced to a cause: the template, the examples, the prompt, the brand rules, or Copilot itself. The same prompts are re-run every quarter.

Can Copilot build charts in our colors?

In our test, it built a real, editable column chart in the brand’s approved chart colors, on a template layout. That was one test, and we do not guarantee it.

What do we need to provide?

A named brand manager, your approved photos, your icon set if you want it in the kit, brand-font deployment by your IT team, and someone to approve the example slides. See who supplies what.
