Updated · AI Detector Index editors
AIDetectPlus sells AI text detection by the word, at 1 credit per word in one-time packs that the vendor says never expire, according to the AIDetectPlus AI detector page read 9 November 2026. The company behind the site is DevZero Inc. of Dover, Delaware, per the about page read the same day. AIDetectPlus is one entry in the register of AI detectors, and this card carries the same fields as the other twenty-one; how this card is sourced sets the rules.

AIDetectPlus scans text. The detector page says the tool works with ChatGPT, Gemini, Claude "and any GPT-family model, on essays, papers, blogs, social posts and PDFs", and the FAQ explains that the signals it reads "are properties of generated text in general rather than fingerprints of one vendor" (aidetectplus.com/ai-detector, read 9 November 2026). Separate detectors are offered for essays, papers, blog and SEO copy, resumes and PDFs, on the stated reasoning that "an essay and a product page do not read alike, and one detector for both is how false flags happen".
The report is the product's distinguishing feature as the vendor describes it: one percentage for the document, a separate reading per paragraph, and each flagged sentence left in place with a plain-language reason, such as formulaic hedging, low burstiness or a lack of specifics. The FAQ says the vendor supports "multiple languages" without naming or counting them, so the languages field stays empty.
On ownership, the about page lists DevZero Inc., 8 The Green, Ste R, Dover, Delaware 19901, with a business registration number, and names two founders (about page, read 9 November 2026). The privacy policy is written for an entity called AIDetectPlus Application at an address in Delhi, India, under Indian law (privacy policy, read 9 November 2026). The card records both addresses as the vendor publishes them. Two comparable credit-metered cards are Copyleaks and Originality.ai; the closest free comparison is ZeroGPT.

Prices below are from the home page pricing section, which carries a USD or INR selector, read 9 November 2026.
The home page and the detector page show the same two larger packs at the same dollar figures; only the home page shows the struck-through list prices and the 5,000-credit pack. The FAQ states that a subscription exists for heavy users without pricing it. API access is listed as a feature of the credit plan; no developer documentation page was found on the site (aidetectplus.com, read 9 November 2026).
On retention, the privacy policy says information "will primarily be stored in electronic form" and may be stored or processed in countries other than India through third parties, with no retention period stated. The detector FAQ says: "If you want your data deleted, contact us using the form below and we will action it" (aidetectplus.com/ai-detector, read 9 November 2026).
What the vendor claims
AIDetectPlus publishes no accuracy percentage. The detector FAQ answers "How accurate is it, honestly?" with: "No AI detector is perfect, and any tool that tells you otherwise is selling you something. Detection is a probability judgement, not a fact" (aidetectplus.com/ai-detector, read 9 November 2026). The home page carries testimonials, a Product Hunt badge and counts of users and documents, none of which the card treats as an accuracy figure.
On false positives the vendor says: "False positives happen to real students who wrote every word themselves. That risk is exactly why the per-sentence reasoning matters more than the headline percentage" (aidetectplus.com/ai-detector, read 9 November 2026). The same FAQ names the two failure cases: "Heavily edited AI text and text written by someone with a very regular style are the two ways results go wrong in each direction."
The vendor also sells an AI Humanizer on the same site, described as able to "pass all popular AI detectors" (aidetectplus.com, read 9 November 2026). A company that sells both the lock and the key is describing a market, not a measurement; the card records the statement because the humanizer field asks what the vendor says about edited text.
What independent studies found
No study record in the index has tested AIDetectPlus. The thirty-five records in the studies index cover other tools, and the detectors with a record are ranked on AI detectors ranked by independent testing.
The vendor's own FAQ is the closest thing to an evaluation on the page: it says short passages are hardest and that results go wrong on heavily edited AI text and on very regular human prose. Those are the same two failure modes that Perkins 2024 measured across seven other detectors, where adversarial edits cut mean accuracy from 39.5% to 22.1% (arXiv 2403.19148, read 9 November 2026).
Where AIDetectPlus appears in the index
Rankings
No ranking lists AIDetectPlus. The four rankings sort on study count, published false positive rate, free words per month and language count, and the card carries no value in any of them: no study, no published rate, a one-time rather than monthly free allowance, and no language count (detectors.json, read 9 November 2026).
AIDetectPlus sits in no audience view at this index version. The full index of AI detectors lists the card with the fields it does state: text, three named generator families, the 3,000-character free box, the 1,000 free credits and the credit packs with their checked prices.
