Question 1

How does AI Scrubber detect AI-generated content?

Accepted Answer

AI Scrubber uses pattern matching to identify 11 categories of AI writing signals: AI buzzwords like 'delve', 'leverage', and 'robust'; professional AI phrases common in LinkedIn posts and resumes; hedging language like 'it's worth noting' and 'certainly'; filler openers like 'Certainly!' and 'Great question'; em dash overuse; transition word overuse (Moreover, Furthermore, Additionally); doubled hedges like 'could potentially'; formulaic AI sentence starters like 'In today's world'; closing phrases; passive voice constructions; and statistically uniform sentence length. Each matched pattern is weighted by how strongly it signals AI authorship, and the weights are combined into a final 0–100% AI likelihood score.

Question 2

Is AI Scrubber free to use?

Accepted Answer

Yes, AI Scrubber is completely free with no hidden costs, no subscription plans, and no signup required. There are no usage limits; you can analyze as many texts as you like. Analysis runs entirely in your browser using JavaScript, so nothing is transmitted to a server and no account is needed. There is no freemium tier or word limit. The tool is 100% free for personal, academic, and commercial use.

Question 3

What does the Humanize feature do?

Accepted Answer

The Humanize button automatically rewrites detected AI patterns into natural human alternatives. Buzzwords are swapped for plain language: 'delve' becomes 'explore' or 'look into', 'leverage' becomes 'use', 'robust' becomes 'strong'. Overused transitions like 'Moreover' become 'Also' or 'And'. Hedging filler like 'it's worth noting' is removed. Filler openers such as 'Certainly! Here is...' are stripped from the start of the text. Case is preserved automatically so the rewritten text reads naturally. The humanized text appears in a panel below the results, where you can copy it with a single click. The original text stays untouched for side-by-side comparison.

Question 4

Does AI Scrubber store or share my text?

Accepted Answer

Yes, your privacy is completely protected. All analysis and humanization runs locally in your browser using JavaScript. Your text is never transmitted to any server, stored in any database, or shared with any third party. AI Scrubber has no backend server, no analytics system that captures text content, and no user account system. You can verify this yourself by opening your browser's network tab while analyzing text — you will see zero outbound data requests related to your text.

Question 5

How accurate is AI Scrubber at detecting AI-generated content?

Accepted Answer

AI Scrubber is highly effective at flagging texts with clear concentrations of known AI writing markers. Because it uses pattern matching rather than a language model, it works differently from statistical detectors like GPTZero or Originality.ai. It performs particularly well on LinkedIn posts, ChatGPT-written essays, AI-drafted cover letters, and blog posts with heavy use of AI buzzwords and corporate phrases. Texts where AI writing is lightly edited, or that were generated by heavily fine-tuned models with minimal AI vocabulary, may score lower. The tool is best used as a fast first-pass checker, not as a definitive forensic test.

Question 6

Which AI models does AI Scrubber detect?

Accepted Answer

AI Scrubber detects writing patterns common to all major large language models, including ChatGPT (GPT-3.5, GPT-4, GPT-4o), Claude by Anthropic, Google Gemini, Microsoft Copilot, Meta Llama, Mistral, and others. Because all LLMs share similar training on internet-scale text, they produce similar stylistic patterns: overuse of certain buzzwords, formulaic sentence structure, hedging language, and formal transitions. AI Scrubber targets these shared patterns, so it is not tied to any single model and works across AI-generated content regardless of which tool produced it.
