Why Aria is different
Private playbooks

Each side independently configures its negotiation position. Your playbook stays private.

Governing-law aware

You pick the governing law. Aria applies rules specific to that law throughout the negotiation.

Your AI agent negotiates for your side

Set your position. Your AI agent takes it through every round, then brings back an agreement for you to check.

Frequently asked questions
What does my first Standard run cost?

Nothing. Your first Standard run is free. If it is a negotiation, its e-signature is free too. If you start with a simulation, that simulation is your free first run. After that, Standard runs are $15 each. No subscription is required.

Does the other party see my playbook?

No. Your priorities, preferences and strategy are yours — the other side never sees them.

Does Aria provide legal advice or legal review?

No. Aria is a commercial negotiation tool, not a lawyer or a law firm. It does not provide legal advice, formal legal review, or certify compliance with local statutes.

You're in control.

You decide what to accept, what to change, and whether to sign. Aria is here to help you reach agreement — on your terms.
