Who are we?

Pine AI is dedicated to using AI to help users handle everyday chores and disputes.

In the United States, calling customer service is often a hassle. You might have to wait half an hour, then spend a long time talking with an agent. If the agent isn’t willing to help, you may be transferred to another department. By the end, a single call can take one to two hours. Many people don’t have that much time to haggle with customer service and end up taking the loss. Others find phone communication difficult due to limited spoken English.

Pine AI is building eloquent, knowledgeable, and exceptionally memory-capable AI Agents that can automate this entire process—making calls, sending emails, and using a computer—to handle tasks like a human secretary.

This is absolutely not as simple as slapping a prompt on a SOTA model. We are looking for exceptional people to tackle this world-class challenge with us.
