liyedanpdx/reddit-ai-trends — reverse-engineered prompt

Build me a Python tool that automatically watches a set of AI related Reddit communities and turns the daily activity into clean trend reports I can read in both English and Chinese.

I want it to pull posts from multiple subreddits, figure out the biggest themes, rank hot topics, compare what is rising over time, and save a daily report every morning. If a post includes an image, a YouTube link, or an article link, it should optionally analyze that content too and fold the useful takeaways into the report. It should also be able to include top comments when that helps, while filtering obvious bot style comments.

Please make it practical to run with Docker, use MongoDB so past data and cached summaries are kept for historical analysis and lower API cost, and support either OpenRouter or Groq for the AI summaries. I also want the latest English and Chinese reports easy to find, and the project README updated with links to the newest reports.

Look up current docs online if you need to.
