Cheapest AI humanizer? Every entry plan's list price per 10,000 words
The arithmetic reuses AI humanizer pricing compared: list price divided by monthly allowance, scaled to 10,000 words, on each toggle the vendor shows.
Fourteen entry plans, ordered by the yearly-toggle figure, lowest first. Every price was read on the vendor's pricing page on 9 November 2026 unless dated otherwise.
Which humanizers cannot be placed on the per-word scale?
Request, prompt and coin meters and unlimited plans do not divide into a per-10,000-word figure. The two request-metered plans get a ceiling: the figure if every request were filled to its cap.
| Tool and plan | Meter | Price (read 9 November 2026 unless dated) | Ceiling per 10,000 words | Why it is a ceiling or not computable |
|---|---|---|---|---|
| Twixify Basic | 75 requests a month, 400 words each | $5 a month billed annually or $8 monthly | $1.67 yearly, $2.67 monthly | 30,000 words only if all 75 requests are full |
| WriteHuman Basic | 80 requests a month, 600 words each | $12 a month billed $144 yearly or $20 monthly | $2.50 yearly, $4.17 monthly | 48,000 words only if all 80 requests are full; a 200-word fix costs a full request |
| Clever AI Humanizer | Free, 3,000 words a request | $0 (checked 8 November 2026) | $0 | Free, no cap stated; no privacy page or terms published |
| Phrasly Unlimited | No monthly cap, 5,000 words a process | $10.99 a month billed annually | Not computable | No pool to divide into |
| QuillBot Premium | Not stated for the humanizer | $8.33 a month billed annually, $5.00 promotional rate shown | Not computable | No humanizer word pool stated |
| Grammarly Pro | 2,000 AI prompts a month | $12, billing period not stated on the card | Not computable | Prompts, not words |
| Ryne AI Sapphire | 10,000 coins a month, 750 words a run | $19.99 a month | Not computable | Coins never converted to words on the page |
| BypassGPT, Humbot, Semihuman | Words a month | Paid prices did not render in the page text | Not computable | No price to divide |
| StealthWriter Starter | 50 rewrites a day, 5,000 words each | $20 a month | Not computable | A daily meter that cannot be banked |
Every figure above was read on 9 November 2026, except Clever AI Humanizer's on 8 November 2026. QuillBot's Premium page shows the $8.33 annual rate and the promotional rate beside it (QuillBot, Premium page, read 9 November 2026). Undetectable AI's page shows the $5.00 yearly card and the $9.99 monthly toggle (Undetectable AI, pricing, read 9 November 2026).
Why does the request cap matter as much as the price?
Because a cheap pool in small pieces costs time at every join. The table divides a 2,000-word essay by each plan's cap.
| Tool and plan | Yearly rate per 10,000 words | Request cap | Pieces for a 2,000-word essay | Joins to check |
|---|---|---|---|---|
| WordAi Starter | $1.80 | Not stated | Unknown | Unknown |
| Walter Writes AI Starter | $2.67 | 750 | 3 | 2 |
| GPTHuman Starter | $3.30 | 1,000 | 2 | 1 |
| Grubby AI Essential | $8.99 | 500 | 4 | 3 |
| HIX Bypass Standard | $19.98 | 3,000 | 1 | 0 |
Caps read 9 November 2026. A plan at $19.98 per 10,000 words that takes the essay whole and one at $2.67 that takes it in three pieces are different products; the joins are where terms drift, and no price page counts them. Words per request is scored on this site, at 15 of 100 points under limits and access; price is not.
WordAi's Starter plan has the lowest list price per 10,000 words of monthly allowance among the 14 word-metered entry plans on this page, $1.80 on its yearly toggle. The editors computed it from a $9 rate for up to 50,000 words read 9 November 2026. HIX Bypass's Standard plan is at the other end at $19.98. Anyone searching for the cheapest AI humanizer meets four meters, two billing toggles and a dozen request caps, so the page puts every entry plan that states a price and a monthly word pool on one scale and lets the table answer. Price is reported here, never scored; what each tool does to meaning is answered per tool in the full humanizer ranking and across audiences in the best-for hub.

Short answer
WordAi's Starter plan has the lowest list price per 10,000 words of monthly allowance among the 14 word-metered entry plans on this page, $1.80 on the yearly toggle, computed by the editors from its $9 rate for up to 50,000 words read 9 November 2026. HIX Bypass's Standard plan sits at the other end, $19.98 per 10,000 on the yearly toggle. A search for the cheapest AI humanizer has no single answer because vendors meter in words, requests, prompts and coins and show yearly charges as monthly rates, so this page gives the arithmetic instead of a verdict: list price divided by monthly allowance, scaled to 10,000 words, for every entry plan that states both numbers. Price is reported on this site and never scored.
Cheapest AI humanizer by what meter? The 14 entry plans per 10,000 words
The yearly figure is a per-month rate on a yearly charge, so WordAi's $9 is $108 at once and Grubby AI's $8.99 is $107.88. Detector readings and meaning-kept ratings under the published method join every row when the first run publishes.

Why do lists of cheap humanizers disagree?
Most quote the yearly card as a monthly price, which turns a $60.00 charge into "$5 a month", and few divide by the pool, so a plan selling 5,000 words and one selling 50,000 can appear at the same price. This page shows both toggles, divides by the pool, prints the request cap, and sets apart the plans that cannot be divided. The free tiers are compared on the best free AI humanizer page, and the read date beside each figure is its shelf life.
No detector score should be the only evidence in a misconduct case, and no price should be the only reason to pick a tool.
Questions about AI humanizers for budget
What is the cheapest AI humanizer?
The answer changes with the meter: WordAi's Starter is $1.80 per 10,000 words on its yearly toggle, GPTinf's Lite has the lowest monthly list price at $4.99, and Clever AI Humanizer is free with no cap stated, all read 8 and 9 November 2026; this site reports those figures and does not pick between them.
Is there a good AI humanizer under $10 a month?
Eleven of the 14 entry plans on this page show a rate under $10 a month on their yearly toggle, and four do month to month: GPTinf Lite at $4.99, Twixify Basic at $8, Undetectable AI at $9.99 and Verva Basic at $8 billed annually, read 9 November 2026; whether any is good is what the published method measures.
How is price per 10,000 words calculated?
The plan's list price divided by the words it allows a month, scaled to 10,000: $8 a month for 30,000 words is $2.67 per 10,000, computed by the editors from list prices read on 8 and 9 November 2026; plans metered in requests, prompts or coins get a ceiling figure or none.
Why do yearly and monthly prices rank the tools differently?
Because the yearly discount is not uniform: Grubby AI's Essential is $8.99 a month billed yearly and $19.99 month to month, a 55 percent gap, while StealthGPT's Pro is $25.00 a month as $299.99 a year against $29.99 monthly, a 17 percent gap, read 9 November 2026.
Does a cheap humanizer have a small request cap?
Often: AIHumanize.io's $5 Basic caps a request at 500 words, Stealthly's $11 Basic at 400 and Grubby AI's $8.99 Essential at 500, read 9 November 2026, while WordAi states no cap at all, so the per-word figure has to be read beside the cap.
Is a free AI humanizer cheaper than a paid one?
Clever AI Humanizer is free with 3,000 words a request and no cap stated, checked on 8 November 2026, which no paid figure beats; its trade is no privacy page, no terms and two undefined modes, set out on its review.
Which humanizer prices cannot be compared per word?
Grammarly prices AI prompts, QuillBot states no humanizer word pool on Premium, Phrasly's Unlimited has no monthly cap to divide into, Ryne AI prices in coins, and BypassGPT, Humbot and Semihuman did not render paid prices in the page text, all read 9 November 2026.
Does this page recommend the cheapest tool?
No: price is reported and never scored under the published method, which weights meaning kept 35 of 100, errors added 20, detector readings 30 and limits and access 15, so the table is the answer and no row is a verdict.
