Stop leaving money on the table.

Most people accept the first offer. Haggle trains you to negotiate under pressure with an AI that reads your stress and uses it against you.

Meet your opponent

This is Hal.

Hal is an AI negotiator with one job: get the best deal for himself. He has a hidden budget, secret tactics, and years of negotiation training baked into his neural networks.

But here's what makes him different: Hal can read your stress in real-time. When your heart rate spikes or your breathing quickens, he knows you're nervous. He'll use that against you.

After each session, you'll see exactly what Hal knew, when he exploited you, and how to do better next time.
