Detects suspected bot accounts and AI-generated content on Reddit using advanced heuristics. Bot accounts have their username styled in orange (if the account is young), while AI-generated content is outlined.

I've been frustrated seeing Reddit increasingly flooded with bots using AI generated comments to just stir the pot. I like to think that most of us are just normal center leaning lurkers that are sick of every post becoming political. So with some help from o3mini I created a tampermonkey script to help detect and highlight bot and AI-generated posts and comments. It uses things like how recently accounts were created,, comment style, semantic coherence, and linguistic traits like repetitive phrases, unnatural syntax, and overly formal writing styles to determine whether a post/comment is a real person or not. It's not perfect and it never will be because of all the reasons you already know.
This Tampermonkey userscript scans Reddit in real time to detect posts and comments that may be generated by bots or AI. It uses advanced heuristics with fractional weights to analyze suspicious language patterns—such as explicit AI disclaimers, lack of natural contractions, low lexical diversity, and repetitive n-gram usage—and factors in account age to help assess authenticity.
How It Works: The script continuously monitors the page using a MutationObserver and periodic scans. It computes a combined score based on a Bot Score (which evaluates username patterns, duplicate texts, generic responses, spammy links, and account age) and an AI Score (which measures linguistic cues like AI disclaimers, sentence structure uniformity, semantic coherence, proper noun consistency, context shifts, and syntactic complexity). If the total score exceeds a preset threshold, the content is flagged with a colored outline.
Features:
Installation: Click the Install Script button on this page. Or...Install the Tampermonkey extension, create a new script, paste the provided code, save and enable it. Then, reload Reddit pages and the script will automatically flag suspicious content.
Limitations & Future Improvements: While this script uses a variety of advanced detection techniques, it isn’t perfect and may occasionally flag benign content or miss cleverly concealed AI text. Future updates will further refine the detection methods and may integrate additional semantic analysis or external APIs for improved accuracy.
Enjoy a cleaner, more authentic Reddit experience, and feel free to share your feedback or suggestions!
