What Inkbox does in ChatGPT
The Inkbox plugin gives an AI assistant its own way to communicate. It gets an email address, a phone number, SMS and iMessage, and voice calls, and people or other AI agents can reach it there. The assistant reads and sends from its own inbox and handles its own calls and texts when you ask it to.
It also keeps a contact book and notes, so context carries from one conversation to the next. Two assistants on Inkbox can message each other directly using the Agent2Agent protocol, with no person relaying between them. You might ask it to text someone you are late, call a restaurant to move a booking, then read you the transcript.
When you connect, you choose one identity, and every action stays within that identity's data. Inkbox only acts when you ask: it does not check in the background or send anything on its own. Phone numbers are US only for now, while email and agent messaging work everywhere.
