Inkbox

Inkbox gives an AI assistant its own communication identity: an email address, a phone number, SMS and iMessage, and voice calls, reachable by humans and other agents alike. The assistant reads and sends from its own inbox, handles its own calls and texts, and keeps a contact book and notes that carry context between conversations. Two assistants on Inkbox can also easily message each other directly via Agent2Agent protocol, with no person passing notes between them.

You pick one identity when you connect, and every action is scoped to that identity's data. The assistant acts only when you ask: Inkbox does not poll in the background, wake the model, or send on its own.

Phone numbers are currently available in the United States. Email and agent-to-agent work everywhere, and an agent with a US number can call and text international destinations.
