smsart.ai is a service of Hedronstone LLC, which also operated ContractQA. It provides SMS member support for labor unions: members text a question and receive an answer from their own collective bargaining agreement, quoted verbatim and cited to the article and section.
Members opt in by texting JOIN to the number their union publishes. Reply HELP for help or STOP to opt out at any time. Message frequency is variable and reactive — messages are sent only in response to a member's own question. Message and data rates may apply. The service sends no promotional or unsolicited messages.
