AAA’s ADR ClauseBuilder

The American Arbitration Association’s® ClauseBuilder tool is designed to assist individuals and organizations develop clear and effective arbitration and mediation agreements.

via Clausebuilder.org.

This is a free tool that may be worth looking at. At present it is only useful for commercial arbitration and mediation clauses. I have not tried out the tool but anything that saves drafting time — with good results — is a benefit.
