DetectArena

DetectArena is a platform that lets you check if a piece of text was written by AI. Instead of running your content through one detector at a time, you send it to multiple popular AI detectors at once and get a side-by-side consensus. Think of it as a battle royale for AI detectors — you paste in your text, and the platform shows you how each tool scores it. The homepage lists recent matchups between detectors like GPTZero, Originality.ai, Winston AI, Pangram, Sapling, and ZeroGPT, complete with win/loss records and percentage scores.

Using DetectArena is straightforward. You type or paste your text into the main input box, optionally select the type of text (General, Academic, Creative & Social Media, Marketing, or Technical), and hit submit. The platform then sends your text to every detector it supports and displays the results in a unified view. The "Battle Royale" mode is the core feature — it shows you exactly which detectors flagged the text as AI and which didn't, along with confidence scores. The site also tracks a leaderboard of detector performance over time, so you can see which tools are winning more matchups.

DetectArena is most useful for educators, content moderators, publishers, and anyone who needs to verify the authenticity of written work. If you're a teacher checking student essays, a editor reviewing submissions, or a researcher studying AI-generated content, this tool saves you from having to test each detector individually. It also gives you a broader picture — because no single detector is perfect, seeing multiple opinions helps you make a more informed judgment. The platform is free to use (no pricing information is shown), and it's a handy resource for anyone navigating the AI detection landscape.
