My bad! Typed too fast late at night.
I think this is a really nice tool for information synthesis. Instead of manually finding info to think about, it appears naturally, and improves the quality of your writing and thought.
However, for this to work, it needs to find information relevant not just to the last sentence, but your entire of thought. This is better-represented by prior paragraphs than the current sentence.
Further, you probably already know what you’re going to write about, so you could “pre-seed” the results with special words. And if you’re looking for something that’s not appearing, you’d need to search for it.
Just very random product thoughts. Cool prototype!
