AI contract review tools read an agreement, pull out the clauses that matter — term, termination, liability caps, indemnities, payment, governing law — and flag what deviates from a standard you set. The best ones redline inside Word or your contract system rather than in a separate window, and explain each flag in plain language so a non-lawyer can act on it. What separates them is the playbook: whether you can define your own positions and fallbacks, or only use the vendor's.

Good enough to catch missing or unusual clauses and to summarize a long agreement reliably; not good enough to sign on its own. The tools are strongest at extraction and comparison against a standard, and weakest at judging whether an unusual clause is acceptable for your deal — that stays a human decision.
Yes — several tools are built for sales, procurement and small-business owners and explain each clause in plain language. For anything with real money or liability at stake, use the tool to prepare questions for a lawyer rather than to replace one.
