Hi Product Hunt! 👋 I am so excited to share PlagiarismGuard with you all today. The Problem: > As AI-generated content becomes the norm, I noticed that traditional plagiarism checkers were either becoming insanely expensive or resorting to stealing user data just to offer a "free" tier. Plus, most legacy tools completely fail at detecting spun text or ChatGPT outputs because they only look for exact word matches. The Solution: I decided to build a better, fast, and completely free alternative. PlagiarismGuard uses a neural pipeline to run semantic analysis—meaning it checks for meaning, perplexity, and burstiness, not just copy-pasted text. ⚙️ The Tech Stack: I built the frontend using Angular with Server-Side Rendering (SSR) and deployed it on Vercel to ensure lightning-fast performance and perfect Core Web Vitals. ✨ What you get for free: Deep scanning (up to 1000 to 5,000 words). AI detection (ChatGPT, Claude) + traditional plagiarism scanning. Complete privacy (Enterprise-grade encryption, and we NEVER save your documents). I will be hanging out in the comments all day! I would absolutely love your feedback on the UI, the detection speed, or any features you'd like to see added next. Thank you! ❤️
