Gemini-marked image sample from 1iki/gemini-watermark-remover, commit bef0303a437902286a18ab4d1586629f198b90b7. Copyright (c) 2025 Jad Copyright (c) 2024 AllenK (Kwyshell) Distributed under the included MIT license. No separate sample-license exception was found in the reviewed repository. The original PNG is byte-for-byte upstream input. The result was produced on 2026-10-22 by this website's pure-JS automatic template matcher and reverse-alpha implementation. No generated logo, inpainting, manual retouching or replacement pixels were added to the after image. Only the detected 48x48 footprint changed. WebP previews are resized/compressed; full result and 96x96 detail crops are lossless PNG. Original Google generation and exact unmarked ground truth are not independently verified. SynthID retention is not claimed.
