About AI Detector Index
AI Detector Index is a registry of AI detectors. It records 22 detectors on the same 14 fields, in the same order, under the same source rules, and indexes 9 published evaluations of them. Every price, limit and accuracy figure on the site names its source and the date it was read. The index was created in November 2026.
Why the index exists
The public conversation about AI detectors runs between two poles. Vendors publish accuracy claims. Explainers argue that detectors fail. Neither gives a reader the record: which detectors exist, what each one covers and costs, and which published studies tested it with what result. The index records that and stops. It has no star ratings, no editor score and no "best overall" verdict. A ranking exists only where a published field can be sorted, and each ranking page says how many of the 72 tools qualified.
Who edits it
The byline on every page is AI Detector Index editors. The editors are a small desk that reads vendor pages and study papers, fills the card fields from them, dates every reading and keeps the corrections log. The desk writes as one voice because the work is clerical rather than personal: a field is either published by the vendor or a study, or it is left out. Readers who want to know how a figure was reached should look at the source link beside it and at the methodology page, which sets out the 14 fields, the two source classes and the ranking rules.
What the index does not do
The index uses published figures only. It does not rate detectors, recommend one or average results from different studies. It does not fill a field a vendor has left blank. It does not print a number without a source and a date in the same paragraph. A detector with no indexed study has no evidence row on its card and sits outside the evidence rankings.
Every page that shows a score carries the same caveat: no detector score should be the only evidence in a misconduct, hiring or publishing decision.
How the site is kept current
Each page shows its own "Updated" date, and the date moves only when a figure or sentence changes. The index version changes when a card or study is added. The current version is 2026.11.13, with 72 cards and 35 study records; version 2026.11 was created on 8 November 2026 with 16 cards and 8 study records. Recheck plans are stated with a date: prices and free tiers on all cards are planned for recheck on 8 December 2026. Every change to a published number is written to the corrections log with the old value, the new value and the source.
How to reach the editors
Corrections, new studies, vendor updates and questions go by email to editor@aidetectorindex.com. The contact page lists what to include. Every message is read, and an accepted correction appears in the log with its date.
The methodology page explains the fields and sources; the editorial policy sets the rules for dates, vendor claims and errors; the corrections log records every change; and the contact page is the route for filing one.
