What it does
Launching Stumbnail, an AI powered tool built to simplify YouTube thumbnail creation. Thumbnails matter, but designing them consistently is time consuming and frustrating. Stumbnail helps YouTubers generate clean, click worthy thumbnails in minutes, without needing design skills. This is an early launch and I’m actively shaping the product with feedback from YouTubers to make it genuinely useful for creators.
Generate click-worthy YouTube thumbnails in seconds with AI. Canvas-based editor, no design skills needed. Choose a plan and start creating.
Turn ideas into thumbnails people actually click in seconds. No design skills needed. Everything you need to know about how Stumbnail fits into a thumbnail workflow. We're an AI YouTube thumbnail generator that turns your ideas into click-worthy visuals in seconds. Just describe what you want or paste your video title, and our AI generates a clean, creator-ready thumbnail. You can adjust colors, personas, text, and layout without starting over. It's built to give you fast results while keeping full creative control in your hands. Not at all. The whole point is that you don't need to know Photoshop or spend hours learning design software. If you can type a sentence, you can make a thumbnail.…from stumbnail.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
