Pay-as-you-go rates

This page states the rates referred to in section 4.4 of our Terms of Service. It applies only to pay-as-you-go usage — usage beyond the AI allowance included in your plan. If you have not turned pay-as-you-go on, nothing on this page can be charged to you.

1. When pay-as-you-go applies

Every paid plan includes a monthly allowance of AI usage. When you reach it, AI features stop for the rest of the billing period — unless you have turned pay-as-you-go on yourself, in Billing. It is off until you turn it on, and you can turn it off again at any time.

Pay-as-you-go charges apply only to usage beyond your included allowance. Usage inside your allowance is covered by your subscription.

2. What is measured

Charges are metered per run, on the AI processing that run consumes — the volume of text processed and the models used, including internal steps and retries you do not see, and the processing a run had already performed if it is cancelled or fails. Amounts are calculated in U.S. dollars and rounded to the nearest cent. Your dashboard shows the charges accrued in the current billing period.

There is no separate charge per file, per page, per project or per seat. Reading pages out of a datasheet PDF is part of the service and is not charged to you.

3. The rate

Because a run's cost depends on how much processing it takes, pay-as-you-go is not a flat price per run. What we can state is what runs have actually cost.

A typical run costs about $0.50.

Basis: 218 runs by 16 paid-plan accounts between September 4, 2026 and September 22, 2026. These are past measurements of real usage, not a quote, a cap or a guarantee, and your own runs may cost more or less. The only limit on what you can be charged is the budget you set.

4. What a budget buys

Worked example. You are on a paid plan, your included allowance runs out on the 20th, and you have set a $5 budget. You run the agent seven more times that month — six ordinary runs at about $0.50 each, and one long one on a large datasheet at about $1.50. Your pay-as-you-go charges come to about $4.50. Because that stays under the collection amount in section 6, nothing is invoiced during the period; it appears on your next regular invoice alongside your subscription. Had one more run taken you to $5, no new run would have started until the period reset — and a run that reached $5 while it was going would have been stopped there, charged for the work already done, with the final total a little over $5.

These examples are illustrations of the indicative figures above, not a guaranteed or expected number of runs: a budget can cover fewer runs than shown, or more, depending on your projects.

5. Your budget cap, and what stops the meter

Before you can turn pay-as-you-go on, you set a maximum amount you are willing to spend per billing period. The maximum is $100. The cap applies per billing period and resets when a new period begins.

We check your accrued charges against your budget before each run starts and stop starting new runs once it is reached. We also check while a run is in progress and stop the run if your budget is reached; you are charged for the work that run had already done. Because a step's cost is not known until it finishes, charges can still end slightly above your budget.

Lowering your budget or turning pay-as-you-go off stops further charges from being incurred. It does not cancel, reverse or refund charges already incurred in the current period. Setting a budget at or below what you have already used stops runs immediately.

6. When you are billed

Charges may be invoiced during the billing period once accrued charges reach a collection amount, rather than only at the end of it. The first such invoice is issued at a smaller amount, which also verifies your payment method; later ones are issued at a standard amount. Today those amounts are $5 and then $10 — or your budget, if your budget is lower than that. Anything below that amount, and anything left at the end of the period, is invoiced with your next regular invoice.

If a payment for usage charges fails, pay-as-you-go is paused until it is resolved. Your plan's included allowance keeps working while it is paused. Unpaid usage charges remain due.

7. How these rates change

We may change pay-as-you-go rates, included allowances or the maximum budget, with reasonable notice to active subscribers. A change to pay-as-you-go rates is published on this page with a new effective date at least 30 days before it takes effect, and we notify active pay-as-you-go subscribers by email. You can turn pay-as-you-go off at any time before a change takes effect, at no cost. Continuing to use pay-as-you-go after a change takes effect constitutes acceptance of the new rates.

8. Questions about a charge

If you believe your usage has been measured or billed incorrectly, contact us at support@tracemind.ai within 60 days of the invoice date and we will investigate. Usage charges reflect processing already performed and are non-refundable except as required by applicable law.
