BypassGPT alternative with bigger word pools and flat pricing

People comparing BypassGPT alternatives are usually weighing two things: how many words the plan really carries once the promotional price expires, and whether the humanized output will clear the specific detectors their work gets run through.

BypassGPT is an established humanizer in the same mainstream category, with promo-led pricing and modest entry word pools (5,000 words a month on the entry plan when we last checked its pricing page in July 2026). Undetected.ai starts at 15,000 words a month on a flat $9 yearly-billed plan, sells 250,000 words a month for $39, and shows our own AI-pattern score before and after, with the reasons behind it.

AI-pattern score

This is our own AI-pattern score, measured here on sentence rhythm, template phrases, vocabulary variety and passive voice. It is not a GPTZero, Turnitin, Originality.ai, Copyleaks or ZeroGPT result, and it does not predict one. Worth knowing: we also ask the rewrite to vary sentence length, drop template phrases and prefer the active voice, so some of the drop is built in. Read the two panels below, not just the number.

The short answer

Undetected.ai is a strong BypassGPT alternative when word volume and a predictable price matter. Its Starter plan carries 15,000 words a month against BypassGPT's 5,000 on Basic, at a flat $9 a month billed yearly rather than a countdown-timer discount, and it takes 1,500 words in one go where BypassGPT limits Basic to 500 words per input. Being straight about it: BypassGPT sells an unlimited tier and we do not. Ours tops out at 250,000 words a month for $39, and while their 51 percent flash sale is running theirs is $19, so a heavy user willing to buy on the timer will pay less there and get more.

Reviewed July 2026. Both tools are capable; the differences below are what actually decide it.

BypassGPT is an established promo-priced humanizer; Undetected.ai carries three times the entry words, flat published pricing, and an AI-pattern score that names what it counted.

Why writers pick Undetected.ai

A price that stays put

Flat published pricing means the number you sign up at is the number you renew at. No struck-through promo math, no renewal surprise.

Good questions

BypassGPT vs Undetected.ai, answered

Yes. Both are mainstream humanizers; Undetected.ai carries three times the entry-plan words (15,000 vs 5,000 a month), publishes flat pricing instead of promo discounts, and shows our own AI-pattern score before and after with the reasons behind it.
Read on August 4, 2026, BypassGPT lists Basic at $12 a month for 5,000 words, Pro at $35 for 30,000, and Unlimited at $39, with a countdown banner cutting those to $8, $15 and $19. Undetected.ai is a flat $9 a month billed yearly for 15,000 words, $19 for 80,000, and $39 for 250,000. We are cheaper per word at the entry tier; they sell an unlimited tier and we do not, so above 250,000 words a month they win outright, and by more while the sale is running.
Yes, and it is easy to miss. The free tier caps each input at 80 words, Basic at 500 and Pro at 1,000, separately from the monthly pool. A 2,000-word essay on Basic has to be split into four passes and stitched back together, which is where rewrites lose consistency. We cap a single run too, and it is fair to hold us to the same standard: 1,500 words on any confirmed account, 200 without one. That same 2,000-word essay is two runs here rather than four, and the ceiling does not move with the plan.
