Originality AI humanizer: what Originality.ai publishes and the tools listed on one set of fields
The table lists eight tools in order of the largest request a cheapest paid plan or free tier accepts, largest first, because an editor checks an article, not a paragraph, and a tool that takes the article whole produces one rewrite. No column is an Originality.ai reading. The Originality.ai column of the published run will be added to this table when the first run publishes. Every figure comes from the vendor's own pricing or product page, checked on 8 November 2026.
None of those lines mentions Originality.ai's reading, because none can yet.
What does Originality.ai publish about its own models?
Originality.ai keeps a public accuracy page, written by Jonathan Gillham and dated 7 November 2026 at this reading, that lists every detection model it has released with the accuracy and false positive figures it measured on its own datasets (Originality.ai, AI detector accuracy, read 9 November 2026). The page opens by saying that "no AI detection tool is ever going to be 100% perfect" and that a single accuracy number without context "is useless".
| Model (Originality.ai's name) | Released | Originality.ai's stated figures | Status at reading |
|---|---|---|---|
| 3.0 Turbo | February 2024 | Accuracy on its toughest dataset rose from 90.2 to 98.8 percent; false positives 2.8 percent | Retired |
| Lite | July 2024 | 98 percent accuracy, under 1 percent false positives | Retired September 2026 |
| 3.1 Turbo | October 2024 | 99 percent or higher accuracy, under 3 percent false positives | Retired |
| 1.1 Lite | June 2025 | 99 percent or higher accuracy, 0.5 percent false positives | Retired |
| 3.2 Turbo | September 2025 | 99 percent or higher accuracy; up to 97 percent on the latest AI humanizers; 1.5 percent false positives | Retired September 2026 |
| Academic | September 2025 | 99 percent or higher accuracy, under 1 percent false positives | Retired September 2026 |
| 4.0 and 4.0 Max | October 2026 | 99 percent or higher accuracy | Current |
All figures above were read on Originality.ai's accuracy page on 9 November 2026 and are Originality.ai's own, measured on datasets it built; the page also lists third-party studies, which are summarised in Originality.ai's words rather than reproduced here. Three things matter for a humanizer search. First, the one figure about humanized text, up to 97 percent, belongs to a model that was retired in September 2026, and the page gives no equivalent figure for the current 4.0 models. Second, Originality.ai explains its numbers with a confusion matrix, separating the true positive rate (AI text caught) from the true negative rate (human text recognised), and says accuracy alone can mislead. Third, the model you are scored on changes: the page records five retirements in 2026 alone, so a reading from spring 2026 came from a model that no longer runs.
What does Originality.ai say a score should be used for?
The same page carries a position statement. Originality.ai writes that it does "not believe that AI detection scores alone should be used for academic honesty purposes and disciplinary action", read 9 November 2026. For its publisher customers it frames the score as a content-integrity check rather than proof, and its page on how detectors are measured tells readers to be sceptical of any detector that publishes an accuracy figure without the supporting matrix.
No detector score should be the only evidence in a misconduct case. Originality.ai's own page says as much for academic cases, and the same logic applies to a freelance writer whose draft scores high: the reading is one model's estimate on one day, and the page documenting that model may say "retired" within a year.
Does an Originality.ai reading affect Google rankings?
No, and Google says so in its own words. Google Search Central states that "appropriate use of AI or automation is not against our guidelines" and that using automation, including AI, to generate content "with the primary purpose of manipulating ranking in search results" violates its spam policies (Google Search Central, guidance about AI-generated content, read 9 November 2026). Google ranks on helpfulness and on what it calls E-E-A-T, and it names no third-party detector in that guidance.
| Question an editor asks | What the source says | Read |
|---|---|---|
| Is AI-written content against Google's rules? | Not when used appropriately; manipulation of rankings is the violation | 9 November 2026 |
| Does Google use a detector score? | Google names no detector; it describes its own helpfulness and spam systems | 9 November 2026 |
| Does Originality.ai claim a ranking effect? | Its accuracy page makes no Google ranking claim | 9 November 2026 |
| So why do publishers check? | Client contracts, editorial policy and disclosure, not a Google rule | n/a |
An editor who runs drafts through Originality.ai to satisfy a client contract has a reason; an editor who does it to satisfy Google does not, by Google's own account.
Why does this page rank nothing by an Originality.ai reading yet?
Because a reading is only meaningful with a date, a model version and a baseline, and this site has not published a run. The published method scans every output on five detectors, Originality.ai among them, records the detector's own label on the run date with a screenshot, scans every input before humanizing so the change is visible, and counts "pass" only where the detector's own label is human. Meaning kept carries 35 of 100 points against 30 for detector readings, because a rewrite that drops a claim has damaged an article even if a detector likes it more.
Originality.ai states 99 percent or higher accuracy for its current 4.0 and 4.0 Max detection models and a 1.5 percent false positive rate for its retired 3.2 Turbo model, all read on its accuracy page on 9 November 2026. An Originality AI humanizer search comes mostly from publishers and SEO teams whose editors or clients run drafts through Originality.ai, and this page answers it without a reading: it lists eight tools on stated fields, explains what Originality.ai publishes about its own models, and links our ranking page and the best-for hub. Content written for the web has its own page, the content writing page, which covers Google's published stance.
Updated
Short answer
99 percent or higher accuracy is what Originality.ai states for its current 4.0 and 4.0 Max detection models, beside a 1.5 percent false positive rate for the retired 3.2 Turbo model, all read on its accuracy page on 9 November 2026. That page also says the company does not believe detection scores alone should decide academic honesty cases. Originality.ai sells to publishers and SEO teams, so the humanizer question here is an editorial one: no tool on this page is ranked by an Originality.ai reading, because this site has published no run yet; the eight humanizers below are listed on stated fields, free tier, cheapest plan, request cap and named modes, and the Originality.ai column of the published run will join the table when the first run publishes.
Which humanizers are listed for Originality.ai, and on what fields?

Why do Originality AI humanizer lists disagree with each other?
Because most of them report one reading from one day and Originality.ai retires and replaces its models, five times in 2026 by its own page, so the model behind a spring reading is gone by autumn. A list with no date and no model version cannot be checked. This page lists stated features and limits, which change only when a vendor edits a page, and the corrections log records each change. When the first run publishes, the Originality.ai column will carry the run date, the model named on Originality.ai's screen, and the baseline reading for every input. The same approach, applied to GPTZero, is on the GPTZero humanizer page.
Questions about AI humanizers for originality ai
What is an Originality AI humanizer?
An Originality AI humanizer is any rewriting tool a person runs on AI text before checking it in Originality.ai; no vendor on this page is connected to Originality.ai, and Originality.ai states that its 3.2 Turbo model was trained for resistance to AI humanizers, read on its accuracy page on 9 November 2026.
What accuracy does Originality.ai publish?
Originality.ai states 99 percent or higher accuracy for its 4.0 and 4.0 Max models released in October 2026, and for the retired 3.2 Turbo model a false positive rate of 1.5 percent and up to 97 percent accuracy on AI humanizers, all read on its accuracy page on 9 November 2026.
What does an Originality.ai score mean?
Originality.ai's page explains its figures with a confusion matrix: a true positive rate for catching AI text, a true negative rate for recognising human text, and a false positive rate for human text wrongly flagged, and it says a single accuracy number without that context is useless, read 9 November 2026.
Does Originality.ai detect humanized text?
Originality.ai states that its 3.2 Turbo model, released September 2025 and retired September 2026, reached up to 97 percent accuracy on the latest AI humanizers in its own testing, read 9 November 2026; it publishes no equivalent figure for the 4.0 models on that page.
Which humanizer does Originality.ai label human?
This site has published no run, so it names no tool on that measure; the published method checks every output on Originality.ai and four other detectors, and the Originality.ai column will be added when the first run publishes.
Does Google penalise AI-written content?
No: Google states that appropriate use of AI or automation is not against its guidelines and that using automation to generate content primarily to manipulate rankings violates its spam policies, read on Google Search Central on 9 November 2026, so an Originality.ai reading is not a Google ranking signal.
Should an Originality.ai score alone decide an academic case?
Originality.ai says no: its accuracy page states that the company does not believe AI detection scores alone should be used for academic honesty purposes and disciplinary action, read 9 November 2026.
Which humanizer takes a whole article in one request?
Phrasly accepts 5,000 words a request on its Unlimited plan, Clever AI Humanizer and HIX Bypass 3,000, and StealthGPT and GPTHuman 1,000, all checked on 8 November 2026; the caps for all eight tools are in the table on this page.
