You pay for what publishes. Nothing else.
A fixed price per published article, set by the quality tier you choose and not by its length. No subscription, no seats, no minimum. A draft that fails the cross-vendor checks is not charged at all, and never reaches your site.
Pick the writer. The cross-vendor checks never come off.
A tier changes which model writes, how strict the validators are, how many revision rounds a draft gets and whether a web-grounded Perplexity cross-check runs. What it never changes is the rule that the writer is not the checker.

Choose a cadence, and see what a month of publishing costs.
Pick how often you want to publish and at which tier. The total is the fixed per-article price multiplied out, which is the whole of the arithmetic.
Your plan, at this cadence
£570 a month
30 articles a month at £19 each, 360 a year.
Charged per published article from a prepaid balance, whatever its length. A draft that fails the checks is not charged and never publishes, so the real invoice is usually a little under this figure.

CodeNest built IT Master and operates it. It also sells done-for-you plans: senior engineers handle the connection, the topic strategy and an expert review pass on top of the engine's own checks, and you approve a plan rather than a queue.
How billing works
How is the price calculated?
Each published article costs a fixed price set by its quality tier, Lite £9, Standard £19, Pro £39 and Premium £69, whatever its length, and you see it before anything runs. A draft that fails the gauntlet is not charged at all and never publishes, so you never pay for a miss.
What does a tier actually change?
The model routing and a few settings: which model writes, which validators run and how strict they are, the retry budget, and whether generated imagery and the web-grounded Perplexity cross-check are included. Every tier keeps the cross-vendor gauntlet. The writer is never its own checker on any tier.
How do I pay?
You prepay a credit balance by card, processed by Worldpay, and each published article debits it. We email you before you run low and pause new generations until you top up, rather than letting a balance go negative.
Can I pay in dollars?
Charges are made in pounds sterling, because we bank in the UK, so a US or other non-UK card is converted by your card issuer at their rate. The dollar figures shown beside each tier are approximate equivalents to help you compare, not the amount that will appear on your statement.
Is there a minimum, or a contract?
No. There is no subscription, no seat count and no minimum volume. You can publish four articles a month or four hundred, change tier between articles, pause a site, or stop entirely and keep everything already published.
What if I want someone to run it for me?
CodeNest, which built and operates IT Master, sells done-for-you plans where its engineers run the setup, the topic strategy and the expert review on top of the engine. Its prices are published at code-nest.dev/pricing.
