Institution-only AI detectors: the cards with no self-serve purchase, and how access is granted
An AI detector is sold only to institutions or enterprises, with no self-serve plan a reader can buy, for 7 of the 72 cards in the index (5 at the count of 9 November 2026, with Ircam Amplify and the Intel FakeCatcher status record added on 10 November 2026), by the free tier and plans fields read on 8 and 9 November 2026: Turnitin's AI writing detection ("only available to customers that license Turnitin Originality"), Turnitin Clarity ("licensed separately at an additional cost" to Feedback Studio customers through an account manager), Compilatio Magister+ (by demo and quote), Pindrop Pulse (every product page ends in "Schedule a demo" or "Talk to a human") and Sensity (a sales form, with new cloud accounts "held for manual review") (guides.turnitin.com, Clarity administrator FAQs, compilatio.net, pindrop.com, docs.sensity.ai). Fourteen more cards sell a self-serve plan and an institution, education or enterprise tier beside it, and sit in the second table. On 10 November 2026 the tenth wave added two rows to the first table, Ircam Amplify (access by application and approval) and Intel FakeCatcher (no access route at all, a status record), and Trinka to the second; StealthWriter (Enterprise, custom) and Monica (Team, $39.90 a seat) name an enterprise or team tier beside ordinary plans and join the note under the second table. Who can get access is a field question, not a quality question: two of the five, Turnitin and Compilatio, carry study records, and the other three carry none. This page is one of the views under AI detectors by feature; the school districts view and the government view read these buyers' other fields, and the full index shows all 72 cards.
- Field 1What the vendor sells it as
- Field 2How access is granted, in the vendor's words
- Field 3Who gets to see results
- Field 4Study records
- Field 5Source, read date
Two card fields, read together. The free tier field must state that no free or trial use is open to the public, and the plans field must list no plan with a published price that a reader can buy without speaking to the vendor: every route to the detector runs through a sales form, an account manager, a demo request or a licence held by an organisation. A vendor that publishes a free tier or a priced plan beside an enterprise tier sells both and sits in the second table, however large its institutional business; a vendor whose free web tool exists but whose API is by contact (Hive, Deepware) sells both for the same reason. Compilatio is the edge case the table states: Magister+, the institutional product, is by demo and quote, while the student product Studium sells credit packs from EUR 4.99 that include AI detection, so the row names the institutional product and the note records the student route. Field rules are in the methodology.
Which fields decide whether a detector is institution-only?
| Detector | What the vendor sells it as | How access is granted, in the vendor's words | Who gets to see results | Study records | Source, read date |
|---|---|---|---|---|---|
 Turnitin | AI writing detection inside Turnitin Originality, or the AI writing add-on for iThenticate 2.0 | "only available to customers that license Turnitin Originality"; Similarity, Feedback Studio and Originality Check customers are told to speak to their account manager | Instructors and administrators; students do not see the AI indicator | 5 | guides.turnitin.com, 8 November 2026 |
 Turnitin Clarity | A paid add-on to Turnitin Feedback Studio | "licensed separately at an additional cost"; "please contact your Turnitin account manager or contact sales"; demos through a sales representative | Instructors, through the Writing Report; students write inside Clarity | 0 | Clarity administrator FAQs, 9 November 2026 |
 Compilatio | Magister+, the institutional licence that includes AI detection (Magister Standard excludes it) | Price by demo request; Studium, the student product, sells credit packs from EUR 4.99 for 5,000 words that include AI detection | Teachers through Magister, students through Studium | 1 | compilatio.net/product/studium, 9 November 2026 |
 Pindrop Pulse | An add-on to Pindrop Protect or Passport (contact centres), Pulse for Meetings, Pulse Inspect | "Schedule a demo" or "Talk to a human" on every product page; Pulse for Meetings bought through a Marketplace Provider, an Authorized Reseller or a Direct Order; a Free Trial Product only "as reflected in the relevant Order" for internal evaluation | The contracting company's agents, meeting hosts and analysts | 0 | pindrop.com/pulse-for-contact-centers, Pulse Meeting Terms, 9 November 2026 |
 Sensity | Cloud platform and API, or on-premise server, workstation and USB dongle | "Talk to sales"; new cloud accounts "are held for manual review" and cannot log in or create API keys until a Sensity administrator approves them; no price, quota or trial term published | Approved workspace members, teams and roles in the web app | 0 | sensity.ai, docs.sensity.ai, 9 November 2026 |
 Ircam Amplify | AIMD, a music detection API and web app for labels, distributors and platforms | "Request access"; "Our team will review your application and, upon approval, provide a demo and a secure onboarding link"; "As a primarily B2B-focused solution, our offering is tailored to professional use cases"; pay-as-you-go from 2,000 tracks with no price published | Approved business accounts and their team workspaces | 0 | ircamamplify.com/request-aimd, 10 November 2026 |
 FakeCatcher | A real-time deepfake detection platform Intel said it had productized in November 2022 | No access route at all: no product page, price, sign-up, download or API exists on intel.com on 10 November 2026; the newsroom post names social media platforms, news organisations and nonprofits as potential users | Not stated; the platform "interfaces through a web-based platform" with no public address | 0 | intel.com newsroom, 10 November 2026 |
Statements as each vendor makes them, read 8 and 9 November 2026 and ordered by study records then name. The "who gets to see results" column is the vendor's description of the product's users, not a statement about data access rights.
Fourteen cards that state both routes, as the plans and free tier fields record them, read 8 to 10 November 2026; a further sixteen cards name an Enterprise, Team, Business or API-by-contact tier beside their self-serve plans (Winston AI, GPTZero, QuillBot, Grammarly, ZeroGPT, Walter Writes, Originality.ai, Undetectable AI, Surfer, Quetext, Sightengine, Illuminarty, WasItAI, GPTKit, Isgen, AI Detector Pro, and from 10 November 2026 StealthWriter and Monica) and are not repeated here because the enterprise row adds seats or volume to a product any reader can already buy.
Why each card is in this view
- AIDI-D-0002Turnitin
the detector is a feature of an institutional licence, visible to instructors and administrators and not to the student whose paper it scores, per the capabilities FAQ (guides.turnitin.com, read 8 November 2026); 5 study records, from 0 of 18 false accusations in Weber-Wulff 2023 to all 40 fully AI papers under 20% in Van Vlasselaer 2026, the most of any institution-only card.
- AIDI-D-0027Turnitin Clarity
a second Turnitin product sold the same way, as a paid add-on to Feedback Studio priced by an account manager (Clarity administrator FAQs, read 9 November 2026); it records a student's writing process rather than scoring a text, and no study has tested it.
- AIDI-D-0032Compilatio
Magister+ is the only Compilatio licence with AI detection for institutions and is sold by demo and quote; the student product Studium sells the same detection in credit packs, which is why the row carries both statements (compilatio.net, read 9 November 2026); 1 study record, the free tool in Weber-Wulff 2023 at 0 of 18 and rank 2 of 14.
- AIDI-D-0041Pindrop Pulse
sold as an add-on to the company's contact-centre products or through resellers and marketplaces, with a free trial defined only inside an Order (Pulse Meeting Terms, read 9 November 2026); no study record, and the vendor's "99% on the ASVspoof5 dataset" is unscored in the ASVspoof 5 record.
- AIDI-D-0038Sensity
the one card whose documentation states that a new account cannot act until a vendor administrator approves it, with no price on any page and on-premise forms for buyers who cannot use a cloud at all (docs.sensity.ai, read 9 November 2026); no study record; 22 upload formats, the most in the file types ranking.
- AIDI-D-0065Ircam Amplify
the request page states that applications are reviewed and approved before a demo and onboarding link are provided, with no self-serve plan or published price (ircamamplify.com/request-aimd, read 10 November 2026); no study record; the API error table names a free account with no stated allowance.
- AIDI-D-0063FakeCatcher
a status record rather than a licence: Intel announced the detector as productized in 2022 and publishes no route to it, so no one can buy it and no institution is named as holding it (intel.com newsroom, read 10 November 2026); no study record.
What the evidence says about institution-only detectors
Selling only to institutions puts the detector where the stakes are highest and the outside evidence thinnest. Of the five, Turnitin has 5 records and Compilatio 1, and the three deepfake and voice products have none; the independently tested ranking lists 35 cards with a record, and the voice and video records in the index are challenges that name no vendor (ASVspoof 5, SAFE 2025, DFDC 2020). Turnitin's five records are also the clearest case in the index of what an institution buys without seeing: the student who is scored cannot run the tool, and the record that matters most to that student, Vanderbilt University's decision of 16 August 2023 to disable the indicator because a stated 1% false positive rate on 75,000 papers implied about 750 wrongly flagged papers a year, is an institution's reading of the vendor's own figure (Vanderbilt 2023 record).
The second table shows the more common shape: a free or priced plan for individuals and an enterprise tier for the organisation, sometimes with different data terms. TruthScan's enterprise tier adds Zero Data Retention, Codeleaks' adds on-premises hosting, Sapling's adds self-hosting and Resemble's adds SOC type 2 documentation, each a term the self-serve buyer does not get; the data retention ranking and the compliance view record the statements that apply to each plan where the vendor makes the distinction. A reader at an institution deciding between the two shapes can read the same fields on every card: the LMS coverage ranking for where the detector appears, the school districts view for the published false positive figure beside the LMS, and the government view for deployment and data region. No detector score should be the only evidence in a misconduct, hiring or publishing decision, and a licence held by an institution does not change what a score means.
Beside the seven institution-only cards sit the twelve that sell an institutional or education programme next to a self-serve plan, listed in the nonprofit and education question, and the twenty that state a seat count or single sign-on, listed in the team seats and SSO view, both read 10 November 2026.

FAQ: institution-only AI detectors
Which AI detectors cannot be bought by an individual?
Seven cards in the index on 10 November 2026, five of them at the first count: Turnitin's AI writing detection (licensed with Turnitin Originality), Turnitin Clarity (a Feedback Studio add-on priced by an account manager), Compilatio Magister+ (by demo and quote; the student product Studium sells credit packs), Pindrop Pulse (demo, reseller or direct order) and Sensity (sales form and manual account approval), by the vendor pages read 8 and 9 November 2026.
Can a student use Turnitin's AI detector on their own paper?
No. The capabilities FAQ says the feature is "only available to customers that license Turnitin Originality" and that instructors and administrators see the indicator (guides.turnitin.com, read 8 November 2026). The Scribbr vs Turnitin comparison sets a free self-serve detector beside it. So does QuillBot vs Turnitin, added 10 November 2026, whose cost table says the vendor publishes no price.
Which institution-only detectors have an independent study?
Turnitin, with 5 records, and Compilatio, with 1 (Weber-Wulff 2023, the free tool); Turnitin Clarity, Pindrop Pulse and Sensity have none in the studies index.
How is access to Sensity granted?
Through a sales form, and the documentation states that new cloud accounts are held for manual review and cannot log in or create API keys until a Sensity administrator approves them; on-premise server, workstation and USB dongle deployments are also by sales (docs.sensity.ai, read 9 November 2026).
Which detectors sell both a self-serve plan and an institutional tier?
Fourteen are tabled above, from Reality Defender's Free and Business plans beside an Enterprise tier to Deepware's free scanner beside an API by contact; another sixteen name an enterprise, team or API-by-contact tier beside ordinary plans and are listed in the note under the table.
Does an institutional licence change the data terms?
Where the vendor says so: TruthScan's Enterprise tier states Zero Data Retention, Codeleaks' on-premises or private cloud hosting, Sapling's self-hosting and Resemble's SOC type 2 documentation, each read 8 or 9 November 2026 on the pricing page cited in the table; the data retention ranking records the default terms.
