No. Your brain is yours alone. Heidi never uses your company's data to train anyone else's AI, and your context never leaks into another customer's answers.
Heidi uses foundation models to reason, and your Cortex to know. Your data stays your context: it is retrieved for your answers, not baked into shared model weights.
Combined with tenant isolation, the boundary is simple to state: what your company knows works for you, and only you.
