@AnthonyLimo yeah, it goes surprisingly deep. This is the first time we saw such a level of depth, one shot. `Design control panel for a humanoid robotics factory floor`
Exploring styles for this new idea with @pendev Just described the vibe I want. I would never come with this style even I had vibe in mind. It would take ages to implement and add two additional drafts just to take a look. Come on!
Ask @pendev agent "create a sitemap of pen.dev on the canvas, import each page." 🤯
@ridd_design @pendev Hey @ridd_design, thanks! Still surprises me how much this unlocks. I just asked the agent `create a sitemap of pen.dev on the canvas, import each page.` It pulled all the pages, all editable. Gotta finally redesign our web...
@tanlethanh_ We did a bunch of optimizations recently. more to come, but actually there is a way to minimize the GPU usage already if needed. Go to Settings > Turn off animations and set the cursor size to hidden. Let us know if that helped.
@mechXsteam nice! Cool to see @pendev & @cursor_ai models designing together.

So which model is the best at frontend design? You can now eval pretty much all of them in pen(dot)dev in realtime in parallel. It's the most versatile design agent, where you can Sign in with ChatGPT, use your Claude subscription, OpenCode Go, Github CoPilot, connect Cursor
I've been using @pendev for a bunch of stuff, but it's really great for creating localised App Store screenshots!
Design with any model, in realtime, in parallel, on canvas.
