Show HN: Browser-Based AI Watermark Remover – No Uploads, Client-Side Only

2 points by axyz7732 2 months ago · 0 comments · 1 min read

I built a simple, fully client-side AI watermark remover that runs entirely in the browser—no images are uploaded to any server, no accounts needed, no ads or watermarks added on output. It targets common AI-generated watermarks like those from Grok, Gemini (Nano Banana / Imagen), Midjourney, etc., using a combination of inpainting heuristics and basic diffusion-style filling tuned for small logo/text overlays. (It's not a full advanced model like Lama or anything cloud-heavy—just lightweight JS + Canvas/WebAssembly ops for speed and privacy.) Why this exists:

People keep asking for free, private ways to clean up watermarks from fun/experimental AI outputs without trusting third-party sites. Most online removers upload your image (privacy risk) or add their own branding/paywalls. This one keeps everything local, works on phones too, and is zero-friction.

Try it here: https://tools.geeksprep.com/ai-watermark-remover (Drag/drop or paste image → process → download PNG)

Feedback welcome: Does it handle your specific watermarks well? Any edge cases (e.g., large/overlaid text)? Suggestions for improvements? Bugs? Happy to iterate if it's useful. It's part of a bigger free tools collection at tools.geeksprep.com (200+ utilities, all client-side/privacy-focused). Thanks for looking!
