The service supports features like end-to-end encryption, group chats, typing indicators, and SMS fallback, and is designed to help teams book meetings and handle customer inquiries at scale. Chert aims to offer a higher-response-rate alternative to cold email by leveraging iMessage's native blue-bubble messaging infrastructure.", "body_md": "Backed by\n\n# infrastructure for reaching people *at* *scale.*\n\nBuild and deploy AI on iMessage to reach people at scale while maintaining quality, trust, and personalized interaction.\n\nChert\n\niMessage\n\nHey!
