I refused to pay subscriptions just to delete an ending, so I "Vibe Coded" a CapCut Watermark Remover (No Login)

The "Vibe Coding" Era 🌊

I confess. I haven't written a single line of boilerplate code in months. And I love it.
We are in the era of Vibe Coding.

Last week, I had a specific problem as a content creator: I love using CapCut for its templates, but I hate that floating ID watermark and the black ending screen that ruins the loop.

I googled "remove capcut watermark". The results?

"Sign up for a free trial" 🛑
"Upload limit: 10MB" 🛑
"Watch this 30s ad first" 🛑

The "old me" would have sighed and opened video editing software to crop it manually.
The "Vibe Coding me" opened my AI editor (Cursor) and said: "Let's build a web tool to kill these watermarks. Fast."

The Challenge: Why existing tools fail

Removing a watermark isn't just about cropping or blurring (which looks ugly). It requires AI In-painting—reconstructing the missing pixels behind the logo.

Most tools hide this feature behind a paywall or a login wall. I wanted a solution that was:

Browser-based (No download).
No Login (I value my privacy).
Specialized for CapCut (Detects the specific ending frames).

How I "Vibe Coded" it in a weekend ⚡

I focused on the Logic, and let AI handle the Syntax.

The Prompt: "Build a React drag-and-drop zone. Connect it to a Python backend using an in-painting model. Optimize it for TikTok and CapCut video formats."
The Vibe: I acted as the Product Manager and the CTO. The AI was my junior dev team.
The Tech Stack: Next.js for the frontend, Python/FastAPI for the inference engine.

Because I didn't spend weeks writing CSS from scratch, I could focus entirely on the User Experience and the AI Model performance.

The Result: VideoWatermarkRemove.com 🚀

I launched VideoWatermarkRemove.com.

It is the epitome of Vibe Coding: simple, fast, and solves exactly one problem.

Here is the specialized CapCut interface I built:

Key Features:

🚫 No Login Required: Just drop your file and get the clean video.
✂️ Specialized CapCut Mode: I fine-tuned the logic to handle CapCut Watermark Removal better than generic tools. It attempts to reconstruct the text area rather than just blurring it.
⚡ Fast Processing: Optimized for short-form content (TikTok/Reels/Shorts).
