1 points by AleksDoesCode 17 hours ago

Hi HN, I’m Aleksandar (founder @ The CodeCave GmbH).

I built GPT Watermark-Remover because I needed a fast, private way to clean AI-generated artifacts out of my drafts.

What it does

Detects zero-width spaces, soft-hyphens and other invisible AI watermarks in text (up to 2 000 chars) entirely client-side Highlights all found markers and removes them with one click Lets you copy the cleaned text instantly

Free tier available; premium plan adds higher char limits via Stripe

Tech stack

React & Next.js (SSR, code-splitting, minimal bundle) Tailwind CSS (light/dark mode, flat minimal UI) Supabase for anonymous session management & analytics Stripe for seamless subscription & token top-ups

Why client-side? All watermark detection runs in your browser—no external APIs, no text storage, full privacy.

I’d love feedback on edge cases, feature requests or integration ideas—please share your thoughts!
