Here's my impressions of your algorithm:

1. read each site

2. rent a 4090 with https://vast.ai to run vllm

3. let llm model invent its own category and tag names freely

4. save 1KB of metadata each

  a. a small local language model that reads each one and writes a name, two or three sentences, a category, and a handful of tags.

5. `code is going up as open source` soon (TM)
