What it does: Load PDFs, notes, or URLs, and it answers and summarizes questions based solely on the content of those materials. Its feature for auto-generating podcast-style audio overviews from your documents is also popular.
Who it's for: People who want to organize and grasp large volumes of material, and those studying or researching.
Strengths: Free to use, and since it sticks to your own documents, it rarely makes things up. The audio overviews are excellent.
Watch-outs: Not suited for general lookups (knowledge outside your materials). It only covers the documents you load.
