Some (importable) sample proofs in the "plain" notation are here. Note that proofs can also be exported in "pretty print" notation (with unicode logic symbols) or LaTeX. See this pdf for an example of how Fitch proofs typeset in LaTeX look. To typeset these proofs you will need Johann Klüwer's fitch.sty.

Is there a proof calculator for basic symbolic logic? This just came to mind while I was messing around on Wolfram Alpha. The thing solves algebra, and basic symbolic logic uses, well, I don't want to say the same sort of symbol manipulation because the overlap is imperfect, but both proofs and algebra work by manipulating symbols via a set of well-defined rules.
