How is this different from regular text search?

Standard search requires exact keyword matches (e.g., 'car'). Semantic extraction understands meaning, so searching for 'vehicle' will successfully extract paragraphs mentioning 'cars', 'trucks', and 'automobiles'.

Can I use it to find specific arguments or sentiments?

Absolutely. You can prompt the AI to 'extract all paragraphs expressing a negative opinion about the product' and it will identify them based on context and tone.

Does it highlight the text in the original PDF?

The tool extracts the relevant text blocks and presents them to you in a clean, compiled list rather than highlighting and modifying the original PDF file.
