Vendor pages: Walter Writes AI, whose homepage carries the pricing block and defaults to yearly billing, read 9 November 2026; GPTHuman pricing page, read 9 November 2026, which shows monthly and yearly toggles side by side with a yearly saving advertised at up to 45 percent.

Which entry plan fits your longest piece?

GPTHuman's, by 250 words. A 1,000-word blog post is one output on GPTHuman Starter and two requests on Walter Starter, both read 9 November 2026. The cap matters most for the common lengths: a 1,500-word essay is two pieces on either tool, a 2,000-word article is two on GPTHuman and three on Walter, and a 2,500-word paper is three on GPTHuman and four on Walter. Each piece is rewritten without sight of the others, so the fewer the pieces the fewer the joins to fix.

Document length	Walter Writes AI Starter, 750 a request	GPTHuman Starter, 1,000 an output
450-word paragraph set	1 request	1 output
1,000-word blog post	2 requests	1 output
1,500-word essay	2 requests	2 outputs
2,000-word article	3 requests	2 outputs
2,500-word paper	4 requests	3 outputs
Next cap up, and its price	1,500 on Pro, $13 a month billed $156 yearly	1,500 on Plus, $25.00 monthly or $14.00 billed $168.00 yearly

Both read 9 November 2026. The step to a 1,500-word cap costs $13 a month at Walter and $14.00 a month at GPTHuman on yearly billing, and the two plans at that step carry 70,000 and 60,000 words a month respectively. GPTHuman's page is specific about how it counts: words per month means words of humanizer output in a billing cycle, and words per output means the maximum length of a single result, read 9 November 2026, so a 1,200-word input on Starter goes through in two pieces and both count against the 25,000.

Which entry plan fits your month?

Walter's, by 5,000 words. Starter is 30,000 words a month against GPTHuman Starter's 25,000, read 9 November 2026, for $96 a year against $99.00. At the lowest printed rates the two plans are 25 cents a month apart and Walter gives 20 percent more words; on monthly billing GPTHuman prints $15.00 and Walter's monthly toggle prices were not in the page as read, so the monthly column is half empty.

Working pattern	Walter Writes AI Starter	GPTHuman Starter
Forty 500-word pieces a month, 20,000 words	40 requests; 10,000 words left	20 outputs if paired, or 40; 5,000 words left
Twenty 1,000-word pieces a month, 20,000 words	40 requests, two per piece	20 outputs, one per piece
Twelve 2,500-word papers a month, 30,000 words	48 requests; pool exhausted	Does not fit; 25,000 is the cap
Twelve months, yearly billing	$96	$99.00
Twelve months, monthly billing	Not in the page as read	$180.00
Price per 10,000 words, yearly billing	$2.67	$3.30

Both read 9 November 2026. Price is reported on this site and never scored. The currency column deserves a sentence of its own: GPTHuman's page shows a dollar sign with no code and the company gives a Montreal, Quebec address, read 9 November 2026, so a buyer should confirm USD or CAD at checkout before treating the 25-cent gap as real.

What do the vendors claim about detectors, and what do the detectors publish?

Both make detector claims this site does not repeat. Walter ships a built-in detector that returns what the vendor calls an authenticity score after each rewrite, read 9 November 2026; a vendor's own detector reading its own output is not independent evidence. GPTHuman's pricing page lists a guarantee against AI detectors on every plan, marked with an asterisk, and describes Shield Guard as an added protection layer that helps preserve the human-style masking of AI content, read 9 November 2026. Neither claim carries an input set, a detector version or a date.

Weber-Wulff and colleagues tested 14 AI text detectors and found every one below 80 percent accuracy, with accuracy falling further on paraphrased and machine-translated text (Weber-Wulff et al. 2023, International Journal for Educational Integrity, read 9 November 2026). Detector makers train against that result. Originality.ai states that its 3.0.2 Turbo model, released September 2025, reached up to 97 percent accuracy on the latest AI humanizers and bypassers, with a false positive rate of 1.5 percent (Originality.ai accuracy page, read 9 November 2026). A humanizer and a detector are moving targets for each other, and a reading is true for its date.

The published method runs each tool on its default mode and its strongest documented mode as a second row, checked on GPTZero, Originality.ai, Copyleaks, Pangram and ZeroGPT. Walter has two rows, Standard and Enhanced; GPTHuman, which names no modes, has one, with Shield Guard recorded as the interface shows it on the run date. Meaning kept is 35 points of 100, errors added 20, detector pass rate 30, limits and access 15. No detector score should be the only evidence in a misconduct case.

Anyone writing for a class should check their institution's AI policy before using either tool; a humanizer does not make undisclosed AI use acceptable. GPTHuman against a request-metered rival is in WriteHuman vs GPTHuman. Both tools here sit in the complete results.
