HumanizerPro.ai is one of the cheaper rewriting tools in this category, with plans at $7, $12 and $19 a month from a named UK company. It publishes more than most competitors do. Here is what its pages say, one arithmetic detail worth checking, and who is better served by a detector.
Paste some text or load the example to estimate AI likelihood.
Everything in this section came from humanizerpro.ai on 16 August 2026. The site served HTTP 200 on every page requested.
The product takes pasted AI text, applies one of three modes named Basic, Standard and Advanced, and returns rewritten output. The free tier allows up to 500 words a month. Alongside the rewriter it offers an AI detector, a plagiarism checker and a fact checker, each at three capability levels tied to your plan. It lists support for eight or more languages, naming English, Spanish, French, German, Italian, Portuguese, Dutch and Russian, and it maintains localised sections at /es, /fr, /de, /it, /pt, /nl and /ru.
| Plan | Monthly | Annual | Words per input | Word allowance |
|---|---|---|---|---|
| Basic | $7 | $84 billed annually | 600 | 180,000 per year |
| Pro | $12 | $144 billed annually | 1,200 | 600,000 per year |
| Advanced | $19 | $228 billed annually | 3,000 | 2 million per year |
Every tier lists multiple language support, the AI detector, plagiarism checker and fact checker at varying levels, plagiarism free outputs, and a three day money back guarantee.
The annual plan is not a discount. Multiply the monthly prices by twelve. Basic at $7 comes to $84, which is exactly the published annual price. Pro at $12 comes to $144, matching. Advanced at $19 comes to $228, matching again. Paying annually commits you for a year at precisely the monthly rate. That is arithmetic on their own published figures, not an inference. Most tools in this category discount annual billing, so if you assumed a saving, there is none to find here.
The allowances are annual, not monthly. Basic's 180,000 words is a yearly figure, working out at roughly 15,000 a month if you spread it evenly. That is still a reasonable allowance for the money, but a headline of 180,000 words next to a $7 monthly price invites a misreading. Check how the counter resets before you plan a heavy month.
HumanizerPro.ai is unusually forthcoming about who runs it. The terms of service name KamranAli Limited, an entity operating under the laws of the United Kingdom, specify English and Welsh Law, and place disputes with the jurisdiction of the courts of England and Wales. Support runs through support@humanizerpro.ai. The homepage describes the business as a team led AI startup.
No registered office address or company number is published, which would be the natural next step in that disclosure. The terms carry an effective date of OCTOBER 22, 2024.
Refunds are stated twice and consistently: We offer a 3-day money-back guarantee for all our plans on the pricing page, and You may cancel a subscription within 3 days for a refund in the terms.
The homepage displays detector results attributed to named systems: 99% Human for GPTZero, 0% AI Indicator for Turnitin, 0% AI for Copyleaks and 93% Human for Originality.ai. The pricing page lists Bypasses AI detectors including GPTZero as a feature of every plan.
Those are HumanizerPro.ai's claims about its own output. We have not reproduced them, no methodology or sample is published alongside them, and we neither confirm nor dispute them. We mention them because they define what the product is sold to do, which matters for the comparison below.
If you arrived here after comparing products with near identical names, one observation may save you time. HumanizerPro.ai and AIHumanizer.ai both use the mode names Basic, Standard and Advanced, and both bundle a detector with the rewriter. That is where the resemblance ends. Comparing the two homepages directly gave zero shared sentences, no links between the domains, different technology stacks, different operators, different language counts, and prices that are not close: $7 to $19 here against $19.99 to $49.99 there. On that evidence these are separate products, and the shared vocabulary is category convention rather than anything more.
Genuine reasons to stay put, listed before we make any case for ourselves.
Price, if rewriting is what you need. At $7 a month Basic undercuts TextSight's entry plan, with a substantial word allowance attached. For rewriting volume per pound spent, they are the stronger buy.
Seven additional languages. They operate in Spanish, French, German, Italian, Portuguese, Dutch and Russian as well as English, with localised sites for each. TextSight's detector is English only. If you write in any of those languages, this alone should decide it.
A named legal entity and a stated jurisdiction. Knowing a UK company stands behind the service, under English and Welsh law, is more than most tools here disclose. If you are expensing this or need to know who you are contracting with, that has real value.
A stated refund window. Three days is short, but it is published in two places and consistent between them. TextSight does not advertise a refund policy.
A fact checker and plagiarism checker in the bundle. We offer neither, so replacing this tool with ours leaves gaps to fill elsewhere.
HumanizerPro.ai's pricing page lists bypassing AI detectors as a headline feature. TextSight builds the detector. Our rewriting is designed to make writing clearer and more concrete, and we publish no claims about how our output scores against GPTZero, Turnitin, Copyleaks or anything else, because tuning against another company's classifier is not what the product does.
So the honest advice for many readers is simple. If you want a cheaper or better rewriter aimed at detector scores, keep looking in that category. We are not a candidate.
People whose problem is assessment rather than production: editors checking freelance work, recruiters reading written assessments, teaching staff handling submissions, content leads auditing a backlog after a change of supplier. In every case the output needed is a judgement plus a record, and a rewriter produces neither.
There is also a diagnostic use. Run your own draft, see which sentences drive the score, and work out whether the writing reads as machine generated or simply generic. The fix for the second is editing, not processing.
No account is required. Anonymous visitors get three checks a day, pooled across the AI Detector and the Document Detector, each capped at 1,000 words. A free account lifts that to 60 checks a day at 5,000 words per check, and every scan run while signed in is saved to Scan History, on the free plan included. Starter allows 200 a day, Pro and above are unlimited. The minimum input is 25 words.
Scores report in three bands: under 30 is likely human-written, 30 to 69 is mixed signals, and 70 or above is likely AI-generated.
We should be direct about one limitation. The detector is an English only ensemble built from DeBERTa, RoBERTa and ELECTRA, and it carries a known false positive bias against people who learned English as a second language. If you are assessing ESL writers, treat a high score as grounds for a closer look and never as a finding in itself.
Annual billing is 25 percent cheaper than monthly, which unlike the comparison above is an actual reduction.
| Plan | Monthly | Annual | Included |
|---|---|---|---|
| Starter | $9.99 | $7.49 | Sentence level analysis, PDF export, 200 scans daily |
| Pro | $19.99 | $14.99 | Unlimited scans, Chrome extension, REST API |
| Business | $39.99 | $29.99 | Teams, branded reports |
| Enterprise | $79.99 | $59.99 | Full capability at scale |
File upload, URL scanning and bulk scanning are included on the paid plans.
Stay with HumanizerPro.ai for cheap multilingual rewriting from a company that tells you who it is. Move to TextSight if you need to evaluate English documents and produce something defensible from that evaluation. The overlap between those two needs is small.
