Vectorize image just landed in pen.dev. You can pair it with logos/icons generated by GPT Image 2/2.5 or so, pretty cool results. This is in addition to AI Pen, which draws vectors from the scratch. Each method is slightly different, so go experiment.

10GB of photos on a single canvas. Is that enough now? :)

Canvas performance in @pendev has been a big priority for us to support your growing projects. This is 10000+ photos, 10GB of content in a single document. Additionally: - Opening a large document now takes about half the time, using roughly 40% less memory. - Layer list and slide panel stay responsive even with hundreds of layers - Selecting thousands of elements on the canvas is near instant Even more improvements coming soon...

My new fav is @pendev, best to bridge the gap from spec <> design <> code. Local Files, BYOK, its well polished unlike Claude Design & that magical feeling of using AI with its multi agents! AFAIK no one has this perfect mix. Love it!
