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.
