The gap nobody fills
Pitch decks matter, dashboards matter more
Most consultancies have a tool for the first and nothing coherent for the second. That gap is exactly where this comparison lives.
We tested Claude Design and Gamma head-to-head on a real consultancy workflow: a six-slide client pitch and a live KPI dashboard, both built from the same brief, the same brand system, and the same prompt.
The real villain here is not either tool. It is the consultancy that accepts a pitch deck that looks fine in isolation but drifts off-brand the moment a second person builds one — or the firm that delivers a dashboard as a static slide rather than a working interactive artefact. Generic tools, applied without discipline, produce generic output. Clients notice.
Knowing the players
What each tool actually is
Claude Design launched on 17 April 2026 as a research preview bundled with every paid Claude subscription at no additional cost. It is powered by Claude Opus 4.7, Anthropic’s newest vision model. It produces decks, prototypes, one-pagers, landing pages, and interactive dashboards. The feature that changes the economics for a consultancy is its design system integration: during setup it reads your brand assets — colour system, fonts, backgrounds, logo variants, component patterns — builds a design system once, and applies it automatically to every subsequent project. Multiple brand profiles are supported, and finished work can be handed straight to Claude Code for full implementation.
Gamma is not a lightweight challenger. Seventy million users, $100 million in annual recurring revenue, a $2.7 billion valuation, and nearly two years as the default for AI-generated decks. The free tier is genuinely strong; paid plans sit between $8 and $20 per seat. Gamma wins clearly on three dimensions: speed to first draft, template breadth, and adoption by non-technical team members. If a marketing lead needs a deck by end of day, Gamma delivers it. That is a real capability, not a consolation prize.
The test
Same brief, same brand, two tools
To keep the comparison fair: a fictional UK consultancy called Northlight Partners pitching an eight-week AI diagnostic to a 38-store homeware retailer called Harper and Finch. Both tools received the same prompt. Both had the same brand system loaded.
Gamma generated the six pitch slides quickly. It picked up the correct client and engagement details, structured the content logically, and exported cleanly to PowerPoint. For a first draft, it is genuinely fast and functional.
Claude Design took longer. It read the full prompt, accessed the brand files, produced a build plan, then wrote and rendered the slides. The output is not perfect at first pass — some elements need manual adjustment. But the result is substantially closer to the actual website aesthetic: correct fonts, correct colour palette, correct backgrounds. When a team member wants a further change, they annotate directly in the interface and send the note to Claude, and the context stays intact.
On brand consistency, Claude Design wins clearly. Its slides looked like they came from the same firm as the website. The Gamma output looked like a well-formatted presentation.
Demo versus deliverable
The dashboard, and the handover to code
On the dashboard, the comparison separates more sharply. Gamma followed the brand colours, laid out the KPI values, and delivered something faster than most PowerPoint output and more visual than a spreadsheet. For a weekly internal update, it does the job. Claude Design built something different in kind, not just degree — the level of detail, the visual structure, and the interactive design were of a different order. And the output does not stop there.
From inside Claude Design you select “Hand off to Claude Code”, copy the output, paste it into Claude Code with the instruction to implement in Streamlit, and within a few prompts you have a fully interactive Python application. The same dashboard that was built visually is now a live application: hosted, shareable, connectable to real data.
A Gamma dashboard is a presentation artefact. A Claude Design dashboard, handed off to Claude Code, becomes a working product.
For consultancies in the Workflow and Agents layers of their AI maturity — firms that have standardised their processes and are ready to deploy AI in production — this handover is what separates a demo from a deliverable.
Where the quality comes from
The design system is the point
The underlying reason Claude Design produces on-brand output is not the model. It is the design system it builds from your assets.
Full control over backgrounds, gradients, font weights, stat tile styles, logo variants, and navigation elements means the tool is not guessing at your brand — it is working from your specification. Messy brand inputs produce messy outputs. If your brand guidelines are a 2019 PDF that nobody refers to, clean them up before asking Claude Design to work from them. The tool amplifies what you give it.
This is also where Claude Design sits in the KWA framework — Knowledge, Workflow, Agents. The design system is the Knowledge input. The prompt-to-output pipeline is the Workflow. The handover to Claude Code is the bridge to the Agents layer, where AI does real work in production. For a firm that has done the preparation — clean brand assets, a clear brief format, a working Claude subscription — the tool collapses the distance between “we have a design standard” and “every deliverable reflects it”.
The trade-offs
The numbers and the honest limitations
Gamma Pro costs $20 per seat. For a 25-person consultancy, that is £500 per month or £6,000 per year. Claude Design is bundled with an existing Claude subscription — if your team already pays for Claude, the tool costs nothing additional. The relevant cost is not the subscription fee, though. It is the switching cost: the time to clean up brand assets, the configuration investment, and the collaboration friction in a tool still in research preview. Those costs are real and worth planning for.
Claude Design is not finished software. Three things to know before you commit:
- Collaboration is basic. If three partners need to edit a deck simultaneously, the tool will not handle that cleanly. Multi-player editing is not there yet.
- Brand assets must be clean. The quality of the design system directly determines the quality of the output. There is no way around the preparation work.
- Speed is not the proposition. Claude Design takes longer than Gamma to produce a first draft. If your workflow depends on fast turnaround above everything else, factor that in.
Making the call
When to use each tool
Use Claude Design when:
- Brand consistency across multiple producers matters more than raw draft speed.
- You need working dashboards or interactive prototypes that clients can actually use, not just view.
- Your team is already on a Claude subscription.
- You want a single tool that handles decks, reports, dashboards, and micro-sites, with a clean handover to code.
Use Gamma when:
- Team members are non-technical and need something that works without configuration.
- You need full multi-editor collaboration today.
- Your workflow is draft-first, refine-later, and volume matters more than finish.
- Data visualisations and interactive outputs are not part of your typical deliverable set.
The practical answer for most consultancies is to use both. Gamma stays in the stack for weekly marketing output, internal updates, and quick-turn decks. Claude Design earns its place for high-stakes client work, reports, anything that feeds into code, and any deliverable where your brand is on the line. What Claude Design ends is the case for settling for a presentation tool when you need a delivery tool. The two have different jobs.
