ACL2 Version 2.7
 A programming language in which you can model computer systems and a tool to help prove properties of those models. Available under GPL and runs on various platforms. Includes related download links.
Bertrand
 Bertrand solves sets of firstorder predicate logic statements for satisfiability (consistency), validity, and equivalence. It also checks single statements for "logical truth" (tautology) and "logical falsity" (selfcontradiction). Subjectidentity is supported. User can "step through" the solution algorithm as Bertrand solves a problem, and/or check the graphic tree produced.
Church
 Program understands the different types of lambda expressions, can extract lists of variables (both free and bound) and subterms, and can simplify complicated expressions. Uses Python.
DC Proof Online
 New proofwriting software to teach the fundamentals of logic and proof. Enables users/students to write errorfree proofs by selecting rules of inference, axioms, etc. from convenient dropdown menus. Includes tutorial and exercises.
Gateway to Logic
 A collection of webbased logic programs offering a number of logical functions: interactively or automatically build proofs, check theorems, and operate on propositional logic formulae.
Isabelle
 A generic theorem proving environment developed at Cambridge University (Larry Paulson) and TU Munich (Tobias Nipkow). Includes logic, documentation and free download.
j'Imp Theorem Prover
 An automatic theorem prover based on set of support and ordered resolution for firstorder logic. j'Imp is part of the Orbital library. This library is a Java class providing objectoriented representations and algorithms for logic, mathematics, and artificial intelligence.
llprover
 A linear logic prover that searches a cutfree proof for the given twosided sequent of firstorder linear logic.
LOOM
 A language and environment for constructing intelligent applications. It is a research project in the Artificial Intelligence research group at the University of Southern California's Information Sciences Institute. The goal of the project is to develop and field advanced tools for knowledge representation and reasoning in Artificial Intelligence.
LWB
 Logics Workbench.
MUltlog
 Takes as input the specification of a finitelyvalued firstorder logic and produces a sequent calculus, a natural deduction system, and clause formation rules for this logic.
MUltseq
 A generic sequent prover for propositional finitelyvalued logics.
Proof General
 Comprehensive GnuEmacs and XEmacs interface for several theorem provers including Coq, Isabelle, Lego, and Phox.
ProofPower
 A suite of tools supporting specification and proof in Higher Order Logic (HOL) and in Z notation.
PVS
 The PVS Specification and Verification System. Available for Sparc machines with Solaris 2 and Intel x86 Machines with Linux compatible with Redhat 5 or later. Required is Emacs (version 19 or later), recommended LaTeX and Tcl/Tk. Download by FTP.
Tree Proof Generator
 An implementation of the semantic tableaux method for classical propositional and predicate logic, written in JavaScript/DOM.
WinKE
 An interactive proof assistant based on analytic tableaux, and designed for the teaching of deductive reasoning. Ordering information is available at this site, as are academic papers on the design of the software.
