Reddit AI Agent is a command-line tool written in Python that integrates with the Reddit API using PRAW and the OpenAI GPT-3.5/4 models to automate various content workflows on Reddit. It can retrieve posts, comments, or trending threads from specified subreddits and feed the text into GPT to generate high-level summaries, sentiment analyses, or proposed moderator replies. Users configure the agent by setting environment variables for Reddit credentials and the OpenAI API key, then customize prompt templates and select tasks via a simple JSON config. Executing the script produces structured output files or console logs, which can be reviewed, deployed as posts/comments through PRAW, or integrated into larger moderation and research pipelines.
