We must build a moat to save humanity from AI.
Please regulate our open-source competitors for safety.
Actually, safety doesn't scale well for our Q3 revenue targets.
But the moment users employ a tool like OpenClaw to regain agency over that same data, it's branded as a "security threat" or "exploitation".
The "Authorized Scraping fro Me, But Not for thee" doctrine is becoming the standard ToS.
The main engineering challenge for me wasn’t detection quality, but finding a point that balanced:
• reliability on textured images • millisecond latency • small binary size • zero server-side processing
I also made the extension paid mostly as an experiment to understand pricing, payments, and distribution for small developer tools. Building the payment/licensing flow took more time than the algorithm itself.
If anyone is curious, I’m happy to share more details about the detection heuristics and fill strategy.
Over a few iterations I tried three approaches:
1) OpenCV heuristics Fixed-position detection + color estimation + inpainting. Fast, but fragile: works on flat backgrounds, fails on textured images.

2) LaMa inpainting High-quality reconstruction using a local LaMa model. Very accurate, but slow (~30s/image on CPU) and heavy to ship.

3) Lightweight watermark-specific algorithm Inspired by community implementations and optimized for Gemini’s logo pattern: geometry-aware detection + edge-preserving fill, no neural model. • Binary < 2MB • Millisecond latency • Runs fully locally in browser

I packaged this into a Chrome extension and a local web Gemini Watermark Remover tool: https://geminiwatermarkcleaner.com/gemini-watermark-remover....
Everything runs locally; images never leave the machine.
I also used this as a small experiment in building a paid micro-utility: payments, licensing, and basic marketing turned out harder than the algorithm itself.
Happy to answer questions about detection, inpainting tradeoffs, or browser-side image processing.
And AI has expanded my boundaries — for example, I used to know nothing about image processing, but now with AI help, I’ve learned and use the technology and even built an initial product prototype using OpenCV, which helped my side project get off the ground successfully.
