How BrowserOS neo compares to everything else.
People lump these together as "browser things for AI", but they are three different kinds of tool solving three different problems. Grouping them honestly is most of the answer.
Every page below compares row by row, says plainly who should pick the other tool, and lists the sources we checked. If we got something wrong, tell us.
