What is AI Text Detector
Detect and highlight any text that looks AI-generated! AI Text Detector scans webpages highlighting words, phrases, formatting, and sentence patterns commonly generated by AI (ChatGPT, Claude, Gemini, etc).
What It Does
● Highlights formatting patterns statistically overused by AI ("not just x but y", "what sets x apart is y", etc). ● Highlights AI-likely characters like em & en dashes and others (—, –, …, etc) ● Highlights words & phrases that AI over uses ("Delve", "Bolster", "Differentiate", "Paradigm", etc) ● Highlights phrases AI over uses ("important to remember", "To put it simply", "One thing is clear", etc) ● Full list can be found on github: https://github.com/TheBox193/ai-text-detector
⚠️ Note: Just because a word, phrase, or sentence structure is detected, Doesn't per-se it was written by ai. But the more items are detected in an article, the higher our confidence can be that ai played some role in the writing.
How It Works
● Runs in your browser: no data leaves your computer ● Uses a blacklist of common words, phrases, and sentence regex patterns Test it on this article: https://podcastle.ai/blog/overused-ai-words/

Questions
● Does this use AI to detect AI? No. That's pretty meta, and doesn't come with guarantees, and also would come with usage costs. Sometimes the simplest approach is best. :) ● Did you use AI to build this? Maybe ;) Ai struggles to make production-ready code imo. ● How'd you come up with the list? Mostly observation, googling, and asking ai to research/expand the list haha. ● What AI is this targeting? Any AI, however I'm most familiar with ChatGPT's writing style. So I'm sure there are many gaps.
