Every Gemini image has a semi-transparent "AI" watermark. iLoveWatermark removes it in one click — directly on gemini.google.com, no uploads, zero quality loss. It works by reversing the alpha blend mathematically, recovering the exact original pixels. No AI inpainting, no guessing — just math. Includes a Chrome extension + web tool. Both share the same usage counter. 2 free removals to try. $4.99 one-time for unlimited — no subscription, ever.

Hey Product Hunt! 👋
Builder here. Happy to answer anything about how this works technically.
The interesting part: Gemini's watermark uses standard Porter-Duff alpha compositing,
which means it's fully reversible. The formula is:
original = (blended - watermark × alpha) / (1 - alpha)
No AI, no inpainting — just math. The result is pixel-perfect every time.
The hardest part of building this was actually CORS — Gemini images live on
googleusercontent.com and block cross-origin canvas reads. The fix was opening
the image in a background tab and injecting a script via chrome.scripting.executeScript
to extract pixels from the same origin.
