4.8 out of 5
Scored by a Toolio reviewer after real useOur verdict
Xinliu lives in the browser sidebar and answers questions with real-time web access, so you don't have to switch tabs to look something up. It also condenses long articles into quick summaries and helps outline a document when you're stuck on where to start writing. You wake it with a keyboard shortcut once it's pinned to the toolbar and logged in, and a 4.8-star average across 20 ratings suggests people who work this way find it genuinely useful.
