Vizora is something I’ve been quietly building for a while, and I’m finally excited to share it. It’s an AI-powered thumbnail generator designed to help creators make clean, platform-ready thumbnails without jumping between editing tools. You simply describe the thumbnail you want, and Vizora generates multiple options for YouTube, Shorts, Instagram Reels, and a few other formats. My goal was to make the whole process feel quick, simple, and conversational, especially for creators who don’t want to spend an hour designing every thumbnail.One thing I really wanted to get right was flexibility, so Vizora also has an edit mode where you can tweak the generated thumbnail directly, adjust text, layout, colors, and small visual details without needing to download or open another design app. It’s not meant to replace complex design tools, but it should help you polish your thumbnail just enough to feel proud of it.The tech stack behind it is pretty modern: Next.js, Vercel AI SDK, Nano Banana model for generation, shadcn/ui for components, Better Auth for authentication, and DodoPayments for the checkout flow. Everything is deployed on Vercel, which made the whole development process a lot smoother.I built Vizora because I’ve personally seen how much time creators lose on thumbnails, even when they know exactly what they want. This is my attempt to make that part of the workflow easier, both faster and more fun. It’s still early, and I’m sure there’s a lot to improve, so I’d really appreciate any feedback, ideas, or suggestions you might have. Every comment will genuinely help shape where this goes next.
