Depending on the material, the LLM can be faster. I have used an LLM to extract viable search terms to then go and read the material myself.

I never trust the summary, but it frequently gives me clues as to what keywords could take me to the right area of a source material. Internet articles that stretch brief content into tedious mess, documentation that is 99% something I already know, but I need something buried in the 1%.

Was searching for a certain type of utility and traditional Internet searches were flooded with shitware that wasn't meeting the criteria I wanted, LLM successfully zeroed in on just the perfect GitHub project.

Then as a reminder to never trust the results, I queried how to make it do a certain thing and it mentioned a command option that seemed like a dumb name that was opposite of what I asked for if it did work and not only would it have been opposite, no such option existed.
