The all-in-one platform to preview YouTube thumbnails, test them with your audience, collaborate with your team, and generate new designs with AI — before you hit publish. Love the contrast! The red really pops against the white text. Ship it. Could we try a brighter background? Feels a bit dark on mobile. From first draft to final publish — preview, test, collaborate, and generate thumbnails in one place. Preview your thumbnails in realistic YouTube-style layouts. Compare multiple versions side by side so you always publish your strongest option. Real-time comments, likes, and approvals on every thumbnail. No more feedback scattered across Slack threads and email chains. Create shareable…from thumbnailcollab.com

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
