Three plans.
Every model on all of them.

Every paid plan includes the full agent, every model family, monthly usage credits, and an API key for other tools. Ten credits equal one dollar of usage at our published rates.

Prices in USD, excluding tax; tax is calculated at checkout. The concurrency limit is how many sessions can run at once — it is also how many people can use the account at the same time. Questions: [email protected].

Top-ups

Run out mid-month? Add credits.

Top-up credits are valid for 12 months and are used only after your plan credits are gone. They work on every paid plan.

You payYou getRate
$5100 credits20 credits per dollar
$10220 credits22 credits per dollar
$25580 credits23.2 credits per dollar
$501,240 credits24.8 credits per dollar
$1002,600 credits26 credits per dollar

Top-up amounts include bonus credits on top of the $0.10-per-credit baseline, so larger top-ups go further — up to 2.6× the baseline rate. Top-ups are meant to bridge a heavy week, not to replace a plan: plan credits remain the better rate. Top-ups are non-refundable once any credit has been used, and unused top-up credits stay on the account for 12 months from purchase.

How credits work

One number, every model.

We charge one rate per model, not a different rate per plan. Ten credits are worth one dollar of that rate, and the app shows the cost of each request before and after it runs.

The rule

1 credit = $0.10 of usage at published rates. Ten credits make one dollar.

A request that would cost $3.50 at published rates costs 35 credits.

Every response carries x-nib-credits-charged and x-nib-credits-remaining headers.

Daily and weekly allowances

Each day you can spend up to 25% of your monthly credits, and each week up to 60%. On Plus that is 75 a day and 180 a week.

The caps stop a single runaway session from consuming the month in an afternoon. Normal use rarely reaches either, and unused plan credits still reset each month.

Bring your own key

Free, on every plan.

Add an OpenAI, Anthropic, Google, Azure, Bedrock, or local model key and Nib will use it instead of your credits. Useful if you already have a provider contract, or want to run a local model for routine edits.

Questions

Pricing, answered plainly.

Is there a free trial?
Yes. New accounts include free trial credits so you can run real tasks before paying. No card required. Trial credits are one-time; paid plans reset monthly.
Why is every model on every plan?
Because gating models by tier would sell the thing people actually want. The tiers differ in balance size and concurrency — how much you can do and how many people can do it at once — never in which models you can reach.
Do unused plan credits roll over?
No. Plan credits reset each billing period. Top-up credits are separate and remain valid for 12 months.
What are the daily and weekly caps for?
They stop one runaway session from consuming the whole month in an afternoon. The daily cap is 25% of your monthly credits and the weekly cap is 60%. Normal use rarely reaches either.
Can I change plans later?
Yes. Upgrades take effect immediately and are prorated. Downgrades take effect at the next renewal, and unused credits do not carry across the change.
Can my team share one subscription?
There are no seat licenses. The concurrency limit decides how many sessions can run at the same time — 3 on Plus, 10 on Pro, 30 on Max — which is also how many people can work simultaneously. Each person signs in with their own credentials on a plan that covers it.
Which payment methods do you accept?
Card payments at checkout. The available methods for your region are shown at checkout before you confirm anything.
What happens if I cancel?
Your plan stays active until the end of the period you already paid for. After that the account reverts to the trial state, and any top-up credits remain available for their 12-month window.
What is the refund policy?
First subscription: 14 days, minus usage already consumed. Renewals are non-refundable once the period starts. Full terms are in the refund policy.

Start on Plus. Upgrade when you need it.

Upgrade when the balance or the concurrency limit gets in the way — never for access to a model.
