From Developer to Toolmaker: 3 Chrome Extensions I Built to Solve Real Problems
Hey PH! 👋
I'm an independent developer and software engineer from China. I spend most of my time working with Python, APIs, and trying to turn messy problems into clean solutions.
I built three Chrome extensions in my spare time — each one born from a real need I ran into during work or daily life. Thought I'd share them here. Hope they're useful to some of you too.
1. 🎥 Virtual Camera - Video Replacement
A tool for developers and presenters. It replaces your browser's camera feed with a looping video file.
Use cases: testing video conferencing features, developing WebRTC apps, or giving demos without worrying about lighting or hardware.
Why it's useful: makes video stream testing predictable and controllable. No more "my camera isn't working" moments during demos.
2. 🤖 AI Flavor Detector
We're all drowning in AIGC content. Sometimes you just want to know — is this written by a human or an LLM?
This tool does exactly that. One click, and it scans the main text of any webpage, highlights AI-generated passages, and gives each one a confidence score.
For: researchers, content creators, hiring managers, or anyone who cares about information authenticity.
Features: one-click detection, color-coded highlights with probability scores, full-page statistical reports, switchable LLM backends (OpenAI, Claude, etc.), and supports both English and Chinese.

3. 🪪 ID Photo Studio
Need a passport or ID photo but don't want to visit a studio? This one lets you capture, edit, and download ID photos right in your browser.
AI-powered background removal + optional AI beautification.
Privacy-first: all core processing happens locally on your device. Your photos never leave your browser unless you explicitly choose a cloud-based AI engine.

These are small tools, but I put a lot of care into making them practical and reliable. If you find any of them useful — or have feedback, bug reports, or feature requests — I'd genuinely love to hear from you. Drop a comment or DM me anytime.
Thanks for reading! 🙏
