We have not split these across tiers to make the expensive plans look better. The only thing that changes as you pay more is how much you can process.

What the numbers mean

A standard undergraduate essay is about 1,500 words. That is the number worth measuring plans against, and it is why the free plan's single-scan limit is exactly that — you can run a whole essay through without splitting it up.

On monthly allowances that works out at roughly 1 essay humanized and 6 checked on Free, rising to 53 humanized a month on Studio. Studio takes a 15,000-word document in one pass, which covers a full master's dissertation.

Detection is far more generous than humanizing at every tier, because the two cost us very different amounts — our detector runs on our own model, while humanizing calls a paid AI provider on every request.

Why there is no unlimited plan

Every unlimited plan has a limit — it is just not written down anywhere you can read it before you pay. Ours is written down: 250,000 humanizer words a month on Team, and 2,000,000 for detection.

If you need more than that regularly, talk to us and we will quote you properly rather than sell you a word that means nothing.

What paying does not buy

It does not buy a guarantee that your text will pass any particular AI detector. No plan at any price does, here or anywhere else. Detectors update without notice and disagree with each other on identical text — a promise about tomorrow's score is not one anybody can keep.

What a paid plan buys is volume: more words a month and longer documents in a single pass. That is the honest description, and it is the one we would rather be held to. More on what detection scores actually mean.

Pricing questions

What can I do on the free plan?
The free plan gives you 2,000 humanizer words a month, 10,000 detection words a month, and up to 1,500 words in a single scan. That last number matters most: 1,500 words is a complete undergraduate essay, so you can run a whole piece through in one go rather than chopping it into fragments. No card required.
Why is the detection allowance so much larger than the humanizer allowance?
Because they cost us very different amounts. Detection runs on our own model on infrastructure we already pay for, so it is close to free at the margin. Humanizing calls a paid AI provider for every request. We would rather pass that difference on than pretend the two are equivalent.
How does yearly billing work?
Yearly billing takes 40% off every paid plan and is charged once. Writer is $129.60 a year, Studio $208.80, and Team $424.80 — the same plans, at 40% less than paying month to month.
Why is there no unlimited plan?
Every unlimited plan has a limit; it is just not written down. Ours is 250,000 humanizer words a month on Team. If you regularly need more, contact us and we will quote you properly.
What is the difference between the plans?
Volume, and nothing else. Every plan has the same three tones, the same sentence-level detection and no ads. Paying more raises how many words you can process a month and how long a single document can be.
Does a paid plan guarantee my text will pass an AI detector?
No, and no plan at any price will. Detectors change without notice and disagree with each other on identical text. Paying more buys you more words and longer documents, not a promise about someone else's detector.
