Hey,

"Claude Code just killed ___" is the most overused tweet format of 2026. For once, someone might be right.

A few weeks ago, Anthropic launched Claude Design. Describe a deck, prototype, one-pager, or marketing asset, and Claude builds it for you. Runs on Claude Opus 4.7. Exports to PDF, PPTX, Canva, or standalone HTML.

We've been using it across the team for three weeks. The output goes into client work. No Figma, no Designer, no PowerPoint.

Used Claude Code to summarize my previous Claude trainings. Then rebuilt a 40-slide deck in about 15 minutes.

An Attendo retargeting ad from a set of eight we built in one Claude Design session. The whole point: I don't need to brief a designer for one ad campaign anymore.

Animated banner from a talk I gave at Aalto University. First prompt, one minute, ready to use.

After three weeks, the templates do more work than the slides.

Claude Design has three layers. The brand system holds fonts, logos, and slide patterns. Templates sit on top, saved structures for things we make often. The actual deck builds on a template.

We built a template for our weekly client meetings. When we open it for next week, it asks for the meeting time and who's joining. Then for what shipped, what's blocked, and what's next. It pulls context from last week's notes. Fifteen minutes later the deck is presentable.

The intake form Claude Design generates from our weekly template. Each question maps to a section in the deck.

The token quota is tight. One weekly deck can eat about 10% of weekly allowance. So finish the content in Claude Code first, then let Claude Design handle only the visuals.

The Edit tool lets you fix a typo on a slide without asking Claude. Draw lets you circle a chart element and tell Claude what to change there.

PDF and PPT exports still break layouts on us. Empty pages, boxes stacking weirdly, elements landing where they shouldn't. The fix is to tell Claude at the start which format you want, or skip both. The HTML export holds up: a single file the client opens locally, animations and motion intact.

The output still varies. Some decks land first try, others need a few rounds. But the quality ceiling is higher than I've seen from any other AI design tool.

The handoff dialog inside Claude Design. One click sends the design source, the conversation history, and a README to Claude Code.

Claude Design's output is a prototype. For real production code, the next step is Claude Code. The bundle includes the design source, the conversation history, and a README. The README explains what we wanted. Claude Code then reimplements the design in whatever framework the target codebase uses.

Try it at claude.ai/design. Pro plan or higher.

The same week, OpenAI launched ChatGPT Images 2.0. For six months, Gemini was the only image model worth using. This new OpenAI model is the first that catches up.

The race isn't over. If you're locked into one model, you'll miss the next one. Platforms like fal.ai and Weavy give you access to dozens behind one API. We use whichever one wins the specific job.

I'd love to hear what you build.
