What you're building
You're building a summarizer that reads a chunk of text and picks out its most 'important' sentences -- using nothing but word-frequency math, the same trick search engines used before deep learning existed. It won't write new sentences like ChatGPT would; instead it plays highlighter, picking the best existing ones. Paste in a news article and watch it extract a surprisingly decent TL;DR in milliseconds.
