About

CordLine

Features
Read full description

CordLine is where missionaries and their supporters stay connected. Missionaries share what's happening on the field — a photo from a new clinic, a prayer request in the middle of a hard week, a praise report when something breaks through. Supporters see it all in one place, and can respond with a prayer, a comment, or a note of encouragement. For missionaries and ministry organizations: - Share field updates, prayer requests, and praise reports with your supporting community - Organize supporters into groups — family, home church, prayer partners — and post to the right audience - Get writing help from Phoebe, CordLine's built-in assistant, when you're short on time or words - Track engagement so you know who's staying connected - Set a security tier for your profile if you serve somewhere that requires extra discretion For supporters: - Follow the missionaries and ministries you care about - See real updates instead of a cluttered group text or newsletter you might miss - Pray, comment, and give — right from the feed - Direct-message the people you're supporting Built for how missions actually works: CordLine keeps every supporter's comments and prayer requests private between them and the missionary — not a public wall. Photos and videos are automatically stripped of location data before they're shared, so a missionary's safety never depends on remembering to check a setting. CordLine is free for missionaries, organizations, and supporters.
