Carnac Live Ink™ · Packages
Compare the Live Ink integration options.
Every plan puts a signed receipt on your AI. These are the same Hive plans priced everywhere else on the site. Carnac Live Ink™ and the Carnac™ decision plane run on all of them. Pick a plan, choose an available payment method, and ship in under a minute.
This is one model, from one person to a company of five thousand. A monthly plan unlocks your per-receipt rate. Every answer emits one signed receipt, and every receipt is metered. These numbers match the full pricing page, which is the source of truth.

How the billing works
Plain and the same across every plan. The monthly number is not a seat license. It unlocks your per-receipt rate, and every call you make emits one signed, billable receipt.
Sets your rate
A flat monthly maintenance fee that locks in a lower per-receipt price and keeps the signing, rails, and audit trail running for you.
You pay for what you sign
Every answer emits one signed receipt, and every receipt is metered. The proof step itself is sub-millisecond, so the cost tracks your real activity.
One governing order form
A broader Assurance engagement receives one integrated quote for the covered workflow. The governing order form must identify the subscription, metered usage, capacity, overage, retention, key custody, support, service levels, and any separately negotiated revenue share. Do not assume one price replaces or stacks with another unless the order form says so.
Straight answers
Does adding Carnac slow anything down?
No. The proof step is sub-millisecond on our signer. The models still take the time models take, and the proof rides on top of that at near-zero cost.
What does Carnac actually do?
It reads each prompt and decides how much proof that request needs, then records which route applied: routine, review, hold, or abstain. It does not form opinions. It determines the required proof and records the provenance.
Who decides the threshold?
You do. Hive meters the proof and records whose threshold applied. We never decide your threshold and we never gate your content.
Can I move up later?
Yes. Every step keeps everything below it. Start with Ink, add Carnac when you need your own policy, move to Full Stack when proof spreads across more surfaces.
How do I pay?
Available methods can include card, bank transfer, or optional USDC on Base. Payment method does not change the receipt evidence, and a treasury payment is not a receipt anchor.
Does Full Assurance add to the monthly price?
No, not automatically. It is a custom annual deployment that replaces the self-serve tier for the covered scope. Any additional metering or services must be stated in the governing order form.
