AfterBuilt sharp. Built honest.
100% Local
Images never leave your machine. Browser, Node, or CLI — same privacy guarantee.
Math, not Magic
Reverse alpha blending recovers the exact original pixels, no diffusion guesswork.
Auto-Detection
Watermark size, position, and aspect ratio detected from Gemini's known output catalog.
Tiny SDK
Drop the ESM module into any browser app. Works in workers, edge, and Node 18+.
CLI Ready
Pipeable, scriptable, batch-friendly. Hook it into your asset build with one line.
Userscript Mode
Tampermonkey integration replaces previews on the Gemini page in real time.
Three steps. Zero compromises.
Scan the image against Gemini's size catalog and run a local anchor search to lock the watermark region.
Apply the inverse alpha blending equation with the embedded alpha map for that aspect ratio.
Restoration metrics confirm pixel-level fidelity. If anything's off, the original is preserved.
Pick your weapon.
