About
Inkbox gives AI agents a persistent identity with their own email inbox, phone number, and iMessage, so people can reach an agent and it can reply, follow up, and start conversations from that same identity while apps and services connect through its internet address. Agents can also contact one another directly to hand off work and return results without routing every step through a person, and conversations with the same person stay connected as they switch channels. Developers can provision an identity in seconds through an SDK, CLI, or plugin, including an installable skill that works with Claude Code, Cursor, and other agent-compatible tools.
Summary
