Reddit AI Detector
Reddit AI Detector is a Chrome extension and backend system designed to analyze Reddit posts and estimate whether they are likely generated by AI or written by a human. The project was built to test end-to-end system design, combining a browser-based user experience with an API that performs text analysis using language model based scoring.
Problem
As AI-generated content becomes more common on Reddit, it is increasingly difficult to distinguish between authentic discussions and posts created for engagement or content farming. This reduces trust in conversations and makes it harder for users to identify genuine responses directly within the browsing experience.
Solution
Reddit AI Detector integrates a Chrome extension with an API that processes text from Reddit posts. The backend tokenizes the input and uses a GPT-2 language model to compute perplexity and burstiness scores, which are used to estimate the likelihood that the text is AI generated. The results are returned to the extension in real time, providing users with seamless, in-context analysis while browsing Reddit.
