AI detectors with team seats, per-seat prices or single sign-on: the cards whose plans or pages state them
A seat count, a per-seat or per-member price, or single sign-on is stated on 20 of the 72 cards in the index, by the plans, integrations, compliance and deployment fields read 8 to 10 November 2026 and recorded in a team field written to every card on 10 November 2026: 17 cards state seats, 6 state SSO, SAML or SCIM, and 3 (Sapling, Codequiry and Resemble Detect) state both (sapling.ai/pricing, codequiry.com/pricing, resemble.ai/pricing). Four more cards name a team, teams-and-roles or large-teams tier with no seat count and no sign-on statement, and sit in the second table. The field is a statement count, not a quality signal: of the 20, 8 carry a study record and 12 carry none, and GPTZero, the card with the most records in the index at 16, states a two-seat minimum and no price. This page is one of the views under AI detectors by feature; the compliance view reads the named standards beside these seats, the business view reads retention and plans for company use, and the full index shows all 72 cards.
- Field 1Seats as stated
- Field 2SSO, SAML or SCIM as stated
- Field 3Study records
- Field 4Source, read date
Two flags, read from four fields. A card states seats when its plans field gives a seat count ("up to 5 team members", "25 user seats"), a per-seat or per-member price ("$12 USD a member a month", "$20 a seat"), or a seat allowance per tier; a card states SSO when its plans, integrations, compliance or deployment field names SSO, SAML or SCIM by those letters. Either flag puts the card in the first table. A card that names a Team or Enterprise tier "for large teams" or a web app "with teams and roles" but gives no seat count and no sign-on statement has neither flag and sits in the second table, because a tier name is not a seat count. Two phrases that match the letters were read and excluded: Pindrop's "No single signal tells the whole story" is about detection, and Paperpal's sign-in host sso.editage.com is the vendor's own login service, not a customer SSO feature. Turnitin's, Pindrop's and Resemble's Microsoft Teams integrations are a meeting product and count for nothing here. Field rules are in the methodology.

Statements as each vendor makes them, read 8 to 10 November 2026 and ordered by study records then name; "None stated" means the fields read name no such thing, not that the vendor lacks it.
Four cards that name a team tier with neither flag, read 8 to 10 November 2026; the remaining 48 cards name no team tier, seat or sign-on statement on the pages read, and the institution-only view covers the seven that sell only by licence or sales team.

What the evidence says about team plans
A seat count says who can log in and nothing about what the score means, and the two halves of this view show it. The 20 cards with a flag hold between them 44 of the index's study-record attachments, 16 of them on GPTZero, and 12 of the 20 have none, close to the proportion in the index at large: 35 of 72 cards carry a record (independently tested ranking). The records that exist were run on documents and essays submitted one at a time by a researcher, not on a shared workspace, so no record in the index tests whether a team's results are consistent across seats; the same-result question covers what the index knows about repeat scoring.
What a team buyer can read beside the seat count is the data term that comes with it. Sapling's Enterprise tier adds self-hosting to its SSO, TruthScan's Enterprise adds Zero Data Retention, Resemble's Business adds SSO on top of the per-seat Team tier, and Codequiry's Defense tier adds a dedicated server, a DPA and a custom MSA to its 20 instructor seats, each read on the pricing page cited in the table; the compliance view lists the named standards and the data retention ranking the stated periods. Where a vendor publishes no seat count, as the four cards in the second table do not, the buyer has a tier name and a sales form. No detector score should be the only evidence in a misconduct, hiring or publishing decision, and a shared workspace does not change what a score means.

FAQ: AI detectors with team seats and SSO
Which AI detectors state single sign-on?
Six of 72 on 10 November 2026: Sapling (SSO/SCIM on Enterprise), Codequiry (SSO/SAML in its integrations), Resemble Detect (SSO on Business), Surfer (SSO on Enterprise), Compilatio (SSO among the Magister integrations) and Trinka (LMS and SSO integration for institutions), by the plans and integrations fields read 8 to 10 November 2026.
Which AI detectors publish a per-seat price?
Pangram ($20 a seat a month on Team), Sapling ($15 a seat a month from 10 seats on Enterprise), Grammarly and Grammarly Authorship ($12 a member a month billed annually), Originality.ai ($8.62 to $24.95 for an additional seat by tier), Monica (US$39.90 a seat a month) and Copyleaks and Codeleaks (25 seats inside the $99.99 Pro price), by the plans fields read 8 to 10 November 2026.
Which detector states the most seats at a published price?
Copyleaks, with 25 user seats included in Pro at $99.99 a month, read 8 November 2026; Winston AI's Elite, TruthScan's priced tiers and Reality Defender's Enterprise state unlimited seats, the last with no published price.
Does a team plan come with a study record?
Eight of the 20 cards carry one: GPTZero 16, Copyleaks 9, Originality.ai 7, Pangram 4, Sapling 3, Winston AI 2, GPTKit 2 and Compilatio 1; the other 12, Codeleaks among them (its 9 records sit on the Copyleaks text card), carry none, as the studies index records on 10 November 2026.
Which detectors name a team tier but no seat count?
QuillBot (Team Plan, price not shown), AIDetectPlus (Enterprise for large teams), Sensity (teams and roles in the web app) and Ircam Amplify (a Team page for Enterprise accounts), read 8 to 10 November 2026; each is a tier name without a count, so neither flag is set.
