We build a lot of cool decks at Inviso. It’s one of our core services, and part of doing it well means testing new AI tools instead of just reading the takes. So when Cowork, Anthropic’s Claude-powered desktop tool, started getting serious buzz for its PowerPoint capabilities, we did what anyone does before committing to something new. We tested it ourselves (inside the same Microsoft-ecosystem environment our clients work in every day) AND… we read its chart.
Here’s our compatibility report:
↑ Rising sign: Impressively capable
First impressions count, and Cowork’s are strong. Give it a clear prompt and some context, and it builds a structured, coherent deck with layouts, content hierarchy, and visuals, faster than most of us expected. We tested it with brand briefs and the output was great. We’d put it at about 80% there. For AI presentation design, that’s a meaningful starting point.
☉ Sun sign: Strong instincts. Strong opinions.
Here’s where it gets interesting. Cowork is confident. It interprets your brief, makes its own aesthetic decisions, and produces something that looks presentable. On its terms. We tested brand kits, custom templates, and purpose-built skills to try to standardize the output. The decks still looked okay. But they didn’t look like… us. Cowork gets close on brand alignment, logo placement, and color fidelity, but the last 20% is always yours to own.
Our Sr. Creative Director’s take:
“As a Pisces, I trust my instincts. And my instincts say: Cowork is genuinely impressive at the brief-to-design translation. It reads a brief, works the copy into design, handles data and charts better than I expected. But I can spot a Cowork deck from across the room now. Type treatments, text box handling, branding elements. You can see it. A designer still needs to finish the work. Right now, it’s a strong rough draft, not a finished deck.”

♄ Saturn: The accessibility complication
This one surprised us, and it’s worth calling out specifically because accessibility is a service we take seriously. Cowork builds slides by breaking content into individual element boxes. That structure creates reading order complexity that’s significantly harder to fix than in a manually built deck. In some cases, you’re inheriting a more tangled problem than if you’d started from scratch. If your organization has accessibility requirements—and it should—this is a critical consideration, not a footnote.
☿ Mercury: The workflow catch
Cowork is an end-user tool, which means it lives at the individual level. There are no automated pipelines you can build around it, no enforcement mechanism, no way to connect it into a broader content workflow, or to programmatically enforce a consistent output. Even when we provided skills, prompts, and template packages to guide the output, calibration is still manual every time, for every user. Each person picks it up and uses it on their own terms. That’s part of its appeal, and also the source of its governance challenge.
Our Sr. Data Engineer’s take:
“Think of Cowork as the Moon: real gravitational pull for the work you need to do, but each instance bound to its own planet: the individual user. The moment you need shared ownership, governed deployment, or automation integration, you’re in different architecture territory. I wouldn’t build an enterprise workflow on a SKILL.md file. For that, a Copilot agent or Power Platform solution is the right call.”
– Samuel Lopez
So what’s the verdict?
Cowork for AI presentation design is fast, capable, and a real head start on a first draft. Whether it’s the right fit depends on what you need. If you’re looking for a quick foundation you can finish manually, it might be exactly right. If your team has strict brand standards, accessibility requirements, or needs consistent output across users, those last 20% gaps matter.
We’re still testing. If you’re evaluating Cowork for your own deck workflow, we hope this gives you better questions to ask before you fully commit.
P.S. This post was written with Cowork’s help. But the astrology spin? That came to me in an actual dream 😉
FAQs
What is Cowork and what does it do for presentation design?
Cowork is a desktop tool from Anthropic, powered by Claude. It can generate PowerPoint presentations from natural language prompts, including layouts, content, and visuals. It’s designed for individual end-users, not automated workflows.
Can Cowork follow brand guidelines when creating slides?
Partially. Cowork can incorporate brand context through prompts, skills, and templates, but it applies its own aesthetic judgment. Brand kits are not natively supported in a way that enforces strict fidelity. Expect to review and adjust color, fonts, logos, and layout before any output is client-ready.
What are the accessibility limitations of AI-generated slides?
Cowork structures slides by breaking elements into individual boxes, which creates a complex reading order that screen readers struggle with. This is harder to fix than in manually built decks. Teams with accessibility requirements should plan for a dedicated review and remediation step.
Can Cowork connect to automated content workflows?
Not currently. Cowork is an end-user tool with no native support for automated pipeline connections. Each user operates it independently, which means consistency across a team relies on shared guidance and prompts, not system-level enforcement.
Is Cowork better than building a presentation manually?
It depends on your standards and your team. Cowork offers a fast first draft, getting roughly 80% of the way there. The remaining 20% requires manual work for brand alignment, accessibility, and visual polish. For teams with strict brand or accessibility requirements, that gap may offset the time saved.
