ProofTools is a free, cross-platform software application for automatically and graphically generating semantic tableaux, also known as proof trees, semantic trees, analytic tableaux and, less commonly, truth trees, generally used to test whether a formula is a logical truth, or whether a proof/argument is deductively valid. Given a propositional formula, it automatically generates the corresponding truth table. A proof is a sequence of proof lines. The symbols ¬, ∧, ∨, →, ←, ↔, ∀, ∃ can be inserted by typing !, &, |, ->, <-, <->, \A, \E respectively. There is a proof tree generator made by Wolfgang Schwarz which takes arbitrary statements in a few different logics (first order logic, modal logic, propositional logic) and provides a proof that they are tautologies, contingent, always false, valid statements, and so forth automatically. [+] Rules for Sentential Logic: NOTE: the order in which rule lines are cited is important for multi-line rules.

Enter a formula of standard propositional, predicate, or modal logic. In the proof editor, you can dynamically add steps and optionally pin their positions in the proof as hints for students. To insert ¬, ∧, ∨, →, ←, ↔, ∀, ∃ type !, &, |, ->, <-, <->, \A, \E respectively. Since all we need is one countermodel to claim that the deduction is not valid this may be an adequate tool to use for one's purpose.
