So I made a thing Got tired of that Gemini watermark in the corner of Nano Banana images, so I built a little Chrome extension to remove it.It's called "Peel Banana" and I just put it up on the Chrome Web Store. Completely free.- The whole thing runs locally in your browser using a reverse-blending algorithm(based on allenk's GeminiWatermarkTool). - No uploads, no servers, no external API. - Just drag in your images and it spits out clean versions in about a second. Keeps the original quality too. - You can do a whole batch at once if you've got a bunch of images to process.Anyway, figured I'd share in case anyone else finds it useful. Let me know what you think!If this helped you out, would love it if you dropped a rating. Five stars would make my dayBig thanks to anyone who leaves a review
