Cons	Recently acquired by Icertis - ask about roadmap and integration before a long commitment Requires a body of executed contracts and playbooks to work well Redlines inform a lawyer's judgement, they do not replace it	No pricing published, only 'flat, scalable' The 90 percent cost claim is the firm's own Operating under a state regulatory pilot makes it jurisdiction-specific
