COSAction is a vital tool for grassroots activists supporting the Convention of States Project. It equips users with valuable information and resources to engage with state legislators effectively. The app aims to mobilize informed volunteers and supporters across local districts, striving to secure resolutions in at least 34 states for a Convention of States. This convention seeks to propose constitutional amendments related to fiscal restraints, term limits, and reducing federal government jurisdiction.

The core mission of the Convention of States Project is to cultivate a proactive network of grassroots activists committed to self-governance. Through COSAction, users can access news articles, action reports for legislative engagements, notifications, a TelePatriot phone outreach tool, and a leadership directory.
