Undetectable AI vs BypassGPT

Undetectable AI, on both toggles. The yearly toggle shows $5.00 a month and the charge is $60.00 up front; the monthly toggle shows $9.99, both read 9 November 2026. A reader can work out the year either way: $60.00 or $119.88. BypassGPT's page names a Basic plan and an Unlimited plan in its own strings, with Unlimited described as unlimited words per month and per request, read 9 November 2026, and attaches no price to either in the served text. A reader who wants to know what a month costs has to open the page in a browser during whatever sale is running that day and read a sale price with a countdown beside it.

Both read 9 November 2026. Price is reported on this site and never scored, and a price that is not in the page is left out rather than guessed. This page will carry a BypassGPT paid price when one has been read on a stated date.

Very little on either, and in different shapes. Undetectable AI's trial is 250 words in total, checked 8 November 2026, which is one long paragraph and then the paywall. BypassGPT's free plan is 150 words a month at 80 words per input, read 9 November 2026, which is two inputs of about three sentences each, and then the same again next month. The protocol's inputs run 350 to 500 words, so neither free tier takes a protocol input whole: Undetectable AI's trial is 100 words short of the shortest input, and BypassGPT's 80-word cap is under a quarter of it. The free tier that does take an input whole, Clever AI Humanizer's 3,000 words per request with no sign-up, checked 8 November 2026, is compared with Undetectable AI in Clever AI Humanizer vs Undetectable AI.

Both read on the dates above. BypassGPT's free plan has one use the other lacks: its three modes are all listed on the free card, read 9 November 2026, so a reader can run the same short passage through Fast, Creative and Enhanced and see what the ladder does. Undetectable AI names no modes on its pricing page, so there is no default and strongest pair to compare; the published run records whatever the interface shows on the run date.

Both pricing pages name detectors as targets. BypassGPT's lists Turnitin and Originality.ai among plan features and uses promise language about detection that this site does not repeat, read 9 November 2026. Undetectable AI's name makes the same promise in one word. Turnitin's detector is not available to the public, so no page here states a Turnitin pass or fail for either tool. The pages read publish no accuracy figure from either vendor that this site could quote with a source, so none appears here.

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 the detector it names are moving targets for each other, and a reading is true for its date.

What none of those pages measure is whether the rewrite kept the writer's claims. The published method weights meaning kept at 35 points of 100, errors added at 20, detector pass rate at 30 and limits and access at 15, with two editors rating every output blind against its input and five named detectors read on the run date. On the free tiers, neither tool can produce a free row from a whole protocol input, so both free rows on the free ranking will be partial by design, and the paid rows will carry the comparison. No detector score should be the only evidence in a misconduct case.
