AI detectors for business and managers

AIDI-U-01

Updated ·

An AI detector for business has to answer three questions before accuracy comes up: can the tool run inside your own systems, what happens to the text your staff paste in, and can more than one person share the account. On the index those are three fields: api, retention and a stated seat count inside plans. Of the 72 cards, 39 state an API, 67 carry a retention statement from the vendor's privacy policy or docs, 36 state at least one of the three, and 11 state all three. Those 11 cards made up this view at version 2026.11.9 and GPTKit joined on 10 November 2026 with the ninth wave (API docs, seats of 2, 8 and 20, a deletion-on-processing statement), so 12 cards qualified at that version, and Trinka joined later the same day with the tenth wave (API docs, a 90-day deletion default, custom enterprise pricing with no seat count), so 13 now qualify; Quetext and TruthScan joined with the fourth wave of cards on 9 November 2026, the one with unlimited users on its Professional plan and the other with unlimited seats on every plan. Two cards added on 9 November 2026 in the third wave, Undetectable AI and AI or Not, publish API docs and a retention statement but quote business plans without a seat count ("Contact us" and reseller terms), so they stay out until a seat figure is published (undetectable.ai/pricing, aiornot.com/pricing, read 9 November 2026). This page is one of five under AI detectors by use case; the siblings for copywriters and agencies and recruiters filter the same register on other fields, and you can compare them side by side on the full board.

  1. Field 1API docs
  2. Field 2Team seats as stated
  3. Field 3Price as checked
  4. Field 4Languages
  5. Field 5Studies

Three fields, read in order. The API field is a yes only when the vendor publishes developer documentation, and the table links that page. The retention field quotes the privacy policy, or the docs where the policy is silent, because a manager auditing reports is pasting company text into someone else's server. Seats are quoted as the vendor states the count. Language count feeds the languages ranking for teams that write in more than English. Every retention clause in the index is quoted in one table on do AI detectors store the text you paste?. Since 9 November 2026 the data retention ranking sorts the same retention statements by the period each policy states, shortest first, with Scribbr, Phrasly and WasItAI stating no storage, Sapling a 3-day cache and Hive a 14-day default. Field definitions are in the methodology.

Values as each vendor states them, read 8 November 2026; the Codequiry and Reality Defender rows were read 9 November 2026. Studies counts the index evaluations that tested the detector. Codequiry scores source code, not prose, and Reality Defender's free plan covers images only.

Prices come from each pricing page, all read 8 November 2026: Winston AI (a struck-through $29 beside a $14.50 promo price, dollar symbol with no currency named), Pangram, Copyleaks, Sapling, Originality.ai and Walter Writes. The GPTZero figure comes from the vendor blog dated October 25, 2026, because the plan cards on the pricing page did not render (gptzero.me). The Codequiry and Reality Defender figures come from codequiry.com/pricing, which displays a USD base converted to CAD, and realitydefender.com/api, both read 9 November 2026.

Why each card is in this view

  1. AIDI-D-0005Winston AI

    API documented; the pricing page states "up to 5 team members" on Advanced and "unlimited team members" on Elite (gowinston.ai/pricing, read 8 November 2026). The privacy policy dated July 17, 2026 says "We collect and store any text or images you submit for analysis" and that deleting a report deletes the content from active storage (privacy policy).

  2. AIDI-D-0006Pangram

    API documented, Team plan at 2 seats (pangram.com/pricing, read 8 November 2026). The data privacy page says submitted text "is stored for as long as your account is active", can be deleted from the history tab, and offers "Zero data retention options for enterprise API" (data privacy).

  3. AIDI-D-0001GPTZero

    API documented, Professional Team Plan with a minimum of 2 seats (gptzero.me/pricing, read 8 November 2026). The FAQ says "We do not store or collect the documents passed into any calls to our API. However, we do store inputs from calls made from our dashboard" (privacy policy).

  4. AIDI-D-0003Copyleaks

    API documented, Pro Plan includes 25 user seats (copyleaks.com/pricing, read 8 November 2026). The API page says submitted content "is not stored, shared, or used to train public AI models", while the privacy policy revised August 24, 2026 allows "training Copyleaks' models" with an opt-out for direct customers (privacy policy).

  5. AIDI-D-0010Sapling

    API documented, Enterprise from 10 seats (sapling.ai/pricing, read 8 November 2026). The privacy policy says "Your content is stored by us and used only to improve the Service"; the API accepts zero_retention: true to score a text without keeping a copy (privacy).

  6. AIDI-D-0004Originality.ai

    API documented, team seats priced per month (originality.ai/pricing, read 8 November 2026). The privacy policy amended June 17, 2026 says "Unless you opt out, we may use your scan history and scan results to help train and improve our models" (privacy policy).

  7. AIDI-D-0015Walter Writes

    API documented, Teams plan with 10 team members (walterwrites.ai/pricing, read 8 November 2026). The privacy policy says personal information is retained "for as long as necessary to provide you with the Services you have requested" and that text is processed "using our own self-hosted AI models" (privacy policy).

  8. AIDI-D-0020Codequiry

    API and command-line client documented (codequiry.com/usage/api); the pricing page states 1 instructor seat on Grow, 2 on the Advanced add-on and 20 on the Defense add-on (codequiry.com/pricing, read 9 November 2026). The privacy policy last updated October 22, 2026 says source code submitted without an active Rapid add-on is added in anonymised form to a cross-account matching corpus and retained indefinitely, while content submitted with Rapid active is excluded from that corpus and can be deleted on demand (privacy policy). Codequiry detects AI-written source code only; a team that ships code is the reader it fits.

  9. AIDI-D-0033Quetext

    API documented at $0.10 per 1,000 words from a prepaid wallet (quetext.com); the Professional plan states unlimited users with a note to contact support above 150 (quetext.com/pricing, read 9 November 2026). The detector FAQ says scanned content "is not stored, saved, or used to train any models" while section 6.1 of the privacy policy, last updated 14 October 2026, says User Content may be included in AI training with an email opt-out (quetext.com, read 9 November 2026); no study record.

  10. AIDI-D-0034TruthScan

    API documented for text, PDF, image, audio and video (truthscan.com); every plan card states unlimited seats, from Free at 25 results a month to Business at $333 a month for 40,000 results with a Zero Data Retention toggle (truthscan.com/pricing, read 9 November 2026). The privacy policy of 19 September 2025 keeps submitted content 30 days by default, and the terms of 27 August 2026 say User Content "is not your confidential information" and apply zero retention to image and PDF submissions (truthscan.com/privacy, read 9 November 2026); the company is Undetectable Inc., which also sells the Undetectable AI detector and humanizer; no study record.

  11. AIDI-D-0022Reality Defender

    API documented (docs.realitydefender.com); the API page states up to 3 seats on Free, 1 seat on Business and unlimited seats on Enterprise (realitydefender.com/api, read 9 November 2026). The privacy policy last updated August 10, 2026 says personal information is not retained "for longer than is reasonably necessary to carry out the applicable, identified purposes" and states no fixed period (privacy policy). Reality Defender states text detection beside image, voice and video; the free plan analyses images only.

  12. AIDI-D-0045GPTKit

    an OpenAPI-documented endpoint on the Team and Institution plans, seat counts of 2, 8 and 20 and a FAQ statement that content is "immediately removed from our servers" after detection (gptkit.ai/plans, gptkit.ai, read 9 November 2026); 0 of 114 false positives in Orenstrakh 2023 and 4.5% accuracy on manipulated AI text in Perkins 2024, so a manager gets few wrong flags and few catches.

  13. AIDI-D-0055Trinka

    API docs on a developer portal, a 90-day deletion default on Basic and Premium and real-time deletion on the $500-a-year Confidential Data plan (trinka.ai/trust-center, read 10 November 2026); the enterprise tier names API, SDK and on-premise integration with no seat count, so the seats cell carries the plan wording; no study record. Ircam Amplify, added the same day, publishes API docs for music only and no text route, so it stays out of this view and sits on the API view.

What the evidence says for business readers

Business text is edited, templated and often written by non-native English speakers. In Walters 2023, Copyleaks classified all 126 documents correctly with 0 false positives in 42 human papers, Originality.ai (model 1.4) classified 98% correctly with 0 incorrect, GPTZero (Pro) 81% with a 2% false positive rate, and Sapling 65% with 28% returned uncertain (Walters 2023, publisher PDF, read 8 November 2026). In Weber-Wulff 2023, Winston AI scored 36 of 54 documents correct with 0 false accusations in 18 human-written documents, while GPTZero scored 29 of 54 with 9 false accusations in 18 (Weber-Wulff 2023, arXiv, read 8 November 2026).

In Perkins 2024, Copyleaks fell from 73.9% on non-manipulated AI text to 58.7% after adversarial techniques, and GPTZero from 26.4% to 16.7% (Perkins 2024, arXiv, read 8 November 2026). For teams with non-native English writers, Liang 2023 reports an average false positive rate of 61.22% across seven detectors on 91 human-written TOEFL essays, GPTZero, Sapling and Originality.ai among them (Liang 2023, arXiv, read 8 November 2026). Pangram, Walter Writes, Codequiry and Reality Defender appear in no study record in the index.

Four cards state a zero-retention flag, mode or plan (Sapling, ZeroGPT, TruthScan, Resemble Detect) and 17 state a deletion route of some kind, on the deletion routes question, added 9 November 2026. A business whose documents are privileged has the law firms view, added the same day, which requires both a retention undertaking and an enterprise route; the compliance view lists the 10 cards whose vendor names a security or privacy standard.

Three newer pages read this view's fields for narrower buyers: the team seats and SSO view lists the twenty cards that state a seat count or single sign-on, the customer support QA view the two that state all four fields a support QA team needs, and the Pindrop vs Resemble Detect comparison the voice fields a contact centre or hiring team would read, all read 10 November 2026.

How a manager can read a detector report

A detector report is a probability attached to a block of text; reading one well means knowing what was scored and what was left out.

1. Check the input against the minimum before trusting the score. Originality.ai states a 100-word minimum (pricing page, read 8 November 2026); the Copyleaks web platform takes at least 255 characters (product FAQ, read 8 November 2026). A two-line status update sits below both floors. 2. Read the vendor's own caveat before reading the number. Sapling says "A detector score is one input to a review, not definitive proof" (sapling.ai, read 8 November 2026). 3. Separate the document score from sentence highlights. GPTZero states that document-level accuracy exceeds paragraph-level, which exceeds sentence-level (FAQ, read 8 November 2026). 4. Ask what else explains the result. Copyleaks states that Grammarly's AI-based rewriting features may trigger detection while basic grammar and spell-check functions typically do not (copyleaks.com, read 8 November 2026). Templates and pasted policy text shift scores. 5. Talk to the writer and look at the drafting record. Version history and outline notes are evidence; a score is a prompt to go find them. 6. Record the detector, the model version where the vendor names one, the date and the exact text scored, so the result can be reproduced.

No detector score should be the only evidence in a misconduct or hiring decision.

FAQ: AI detectors for business

Which AI detectors fit business use?

Nine cards state all three business fields: Winston AI, Pangram, GPTZero, Copyleaks, Sapling, Originality.ai and Walter Writes, read on 8 November 2026, and Codequiry and Reality Defender, read on 9 November 2026, each publish API docs, a retention statement and a team seat count. Fit depends on which of the three matters to you; the table puts the stated values side by side.

How do I use an AI detector to audit employee reports?

Score only text above the vendor's minimum, read the caveat printed with the score, separate the document figure from sentence highlights, then check version history and talk to the writer. The six steps above are written for this job. A detector flags where to look; the drafting record and the conversation are what you act on.

Does an AI detector store the reports I paste in?

Usually yes, and the policy differs by surface. GPTZero says API calls are not stored but dashboard inputs are (FAQ, read 8 November 2026); Sapling stores content by default and offers zero_retention: true on the API (privacy). Read the retention note before pasting confidential text.

Which detectors here work in languages other than English?

The seven text detectors read on 8 November 2026 each state more than one language. Copyleaks and Originality.ai each state 30, Pangram 24, Walter Writes 20, Sapling 16, Winston AI 11 and GPTZero 5, as recorded from the vendor's pages. Codequiry states 65+ programming languages and no natural language count; Reality Defender publishes no language count. The languages ranking orders every card on the same field.

Can a manager act on a detector score alone?

No. Every vendor in this view says so in some form, and the studies show why: GPTZero recorded a 2% false positive rate in Walters 2023 and 9 false accusations in 18 human documents in Weber-Wulff 2023. A score is a reason to review, not a finding.
