> Why should I believe that Anthropic will care about this product in 2, 3 years?
There's no reason to believe Anthropic will stop caring about this product--they're not Google [1] after all.
> It really feels like Anthropic's product area is extremely overextended at this point.
I don't think so. They have one core product: the Claude model; they're enabling different ways of accessing it. Claude Code for developers, Cowork for general business tasks, and chat for consumers.
This is their first graphic design product, but it fits nicely because once you create a prototype, you can hand it over to Claude Code to make the website, mobile app, or whatever.
The advantage Anthropic has is their ecosystem. A Claude user will be way more productive using Design because all of their context is with Claude; other AI tools don't "know you" the way Claude does. Claude already knows your style and your preferences; it's much more likely to create designs you'd like.
When you go to an AI you don’t normally use, you essentially have to start from scratch.
