Magic Patterns (W23) is one of the fastest-growing design tools in AI, helping product teams turn ideas into interactive, code-backed prototypes in minutes.
@alexdanilowicz and his co-founder, both front-end engineers, built @magicpatterns to solve a problem they had themselves: finding a better way to turn ideas into something visual. They were among the first teams building prompt-to-design tools back in 2023.
In this episode of Design Review, Alex joins YC’s @aaron_epstein to demo Magic Patterns and its new MagicOS canvas, where teams can bring together prompts, images, PRDs, and other context to explore ideas visually.
Then they review a handful of startup websites to break down what makes a site feel “vibe coded,” where founders go wrong, and how to make AI-generated design feel more intentional.

Today we're launching MagicOS. And we've come to the conclusion that designers are NOT getting replaced.
most of the industry moved to the same answer this year: give the agent its own canvas, let it run, hand you the output.
we made a different bet: the canvas should be yours and the agent is your collaborator. that’s MagicOS.
most AI design tools are a linear conversation: prompt, generate, iterate, repeat. a hundred prompts in, you might have a great final design, but the reasoning, rejected directions, and inspiration that got you there are buried in a chat log nobody will ever scroll back through.
MagicOS is a persistent, spatial canvas. Your PRD, inspiration images, design system, variations, rejected directions, final picks - all of it lives together, all in one place, instead of stacked on top of itself and lost.
it’s voice-first. talk to it in real time and watch work land directly on the canvas as you speak.
it’s also multiplayer. your whole team works on the same canvas together.
and it still runs on your design system and components because none of this matters if the output doesn’t look like your actual product.
three months ago, this was internal only at Magic Patterns, my co-founder's weekend project. it’s now live for everyone.
Design everything, everywhere, all at once.

We introduce Maple-Preview, an open-source 20B-A1B ternary-weight reasoning LLM, SOTA in its weight class.
It solves IMO-level problems and runs at 200+ tokens/s on a Mac Mini M4, 5–16× faster than efficient models like Gemma 4, Qwen3.5, and gpt-oss.

🧵1/4 AI Is Radically Democratizing Legal Services
Contrary to fears that AI will create chaos in courts, new research shows AI is becoming the great equalizer of justice. From victim impact statements to legal research, AI is making quality legal services accessible to everyone, not just the wealthy.
imagine if soham played on each company's club soccer team and then he had to show up to a tournament lol
