Open Instinct
Open Instinct is an open-source personal agent that performs tasks via text message, operates within a microVM, and communicates with other trusted agents.
Open Instinct is an open-source clone of Instinct that functions as a personal agent controlled via text message. The system assigns the agent a dedicated phone number, email address, and agent-to-agent endpoint. Each agent runs in its own Linux-based microVM on Maritime, executing a Pi agent loop that connects with applications through Composio and manages payments via Stripe Link. Users define agent behavior and persona through editable files, while a hard-coded permission system regulates how other agents interact with the user's data. It creates and sends files, handles calendar requests, and facilitates payments using single-use cards without storing financial credentials.
