Analysis of text for signs of AI-generated content

Implement a JS function for analyzing text content for compliance with the characteristics of AI-generated. Something similar to https://quillbot.com/ai-content-detector but exclusively on the front end / javascript. 

- typical structures, word frequency, and other criteria 

- English dictionary, may apply for other languages in the next version

- parts of the text (sentences or paragraphs) that meet the threshold value should be returned with minimal explanation (probability, reference to the model)

- definitions for both AI and human-generated can be added, which will balance the probability values 

Requirements: 

• For the dictionary and structures of AI and Human-written, using AI = OK
• Using third-party JS libraries is possible, provided they can be used in a Chrome extension or another project 

Acceptance: 

• Run through quillbot or another AI detector, compare results (Take texts from sources that are 100% not AI (year of writing or the same Wikipedia and other articles, as well as texts from ChatGPT/Grok/Gemini)
• Absence of "false starts" (defining human-written content as AI)
