Private classification and alert source feeding platform and shared-database workflows
The Terrorist Content Analytics Platform is Tech Against Terrorism's service for collecting, classifying and alerting platforms to terrorist-content material, with related archive and application-programming interfaces. It combines in-house assessment and partner referrals with information that recipient services can use in their own review processes.
Its policies combine selected designation authorities with Tech Against Terrorism's consensus, threat and splinter assessments. Delisting follows removal from all followed lists, while historical pre-delisting material continues to be alerted. The Year 2 report describes 36 disputes about automated URL-availability status, with 35 changed; these are not terrorist-label reversals. Current hash interfaces separately document withdrawal metadata and feedback. GIFCT applies its own inclusion parameters to TCAP inputs. The older Altitude adapter receives URL-alert metadata and must not be treated as evidence about the current hash API's correction handling.
Altitude — inspected public implementation → Terrorist Content Analytics Platform

Export requires diagnostics active and maps BLOCK to REMOVE. Selection uses the latest review in the interval without the inspected condition requiring published state or successful downstream delivery. This is code semantics, not observed false reporting or TCAP acceptance of a disagreement.
TCAP inclusion and verification rules → Terrorist Content Analytics Platform
Selected designation authorities combine with TAT consensus/threat and splinter assessments. Entity removal from all followed lists triggers delisting; historical pre-delisting material continues to be alerted. This is not a worked correction of a false item label.

Pinned code assigns confidence component 3 for TCAP or other qualifying evidence. Separate severity contributes to priority, so TCAP alone does not guarantee top overall rank. Neither confidence nor queue rank is a moderation verdict or calibrated probability.
TAT Trusted Flagger Platform → Terrorist Content Analytics Platform
TAT describes categorized partner URL submissions with analyst/AI review and metadata for platform requests. Five-tier/125-plus-platform claims are advertised capabilities, not proof of universal integration or mandatory takedown.
Terrorist Content Analytics Platform → Altitude — inspected public implementation
2024-08-08 – 2024-08-08
2024 adapter imports source identifier/report date, group text, flags, URL and availability. This is the older URL-alert interface; it is not evidence of current content-hash deletion handling or ignored corrections.
Canada TCAP Phase 2 — agreement 22841 → Terrorist Content Analytics Platform
Two publicly described workstreams identify intended outputs. No cost annex allocates the contribution specifically to Altitude, the LLM, an API or a supplier invoice; no accepted milestone acquired.
Terrorist Content Analytics Platform → TCAP content-hash API — current public docs
Authentication introduction presupposes an existing onboarded TCAP or Archive account. It does not publish the current decision-maker, full eligibility contract or unrestricted access.
Terrorist Content Analytics Platform → GIFCT Hash-Sharing Database
Taxonomy names TCAP but requires GIFCT inclusion parameters too. This filter defeats an inference that every TCAP label automatically enters HSDB.

Tech Against Terrorism → operates the classification and alerting service → Terrorist Content Analytics Platform
Operator accounts explain in-house collection/verification and advisory alerts; provider enforcement remains separate.
Canada TCAP Phase 2 — agreement 22841 → specifies archive/classification and moderation-workflow development → Terrorist Content Analytics Platform
Two publicly described workstreams identify intended outputs. No cost annex allocates the contribution specifically to Altitude, the LLM, an API or a supplier invoice; no accepted milestone acquired.
UK voluntary infrastructure guidance — 2024 → recommends TCAP where applicable → Terrorist Content Analytics Platform
2024-02-15 – 2024-02-15
Named-tool recommendation and legitimacy route, not mandatory subscription, exclusive provider choice or an individual takedown order.
TCAP inclusion and verification rules → sets inclusion, imitation and delisting parameters → Terrorist Content Analytics Platform
Selected designation authorities combine with TAT consensus/threat and splinter assessments. Entity removal from all followed lists triggers delisting; historical pre-delisting material continues to be alerted. This is not a worked correction of a false item label.
Tech Against Terrorism → reported correcting URL-availability statuses after platform disputes → Terrorist Content Analytics Platform
December 2021–November 2022 reporting period, not a current API service-level promise.
Reported by the cited source
Year 2 report records 36 disputes, all automated status issues; 35 statuses changed and one remained active. These are not 36 terrorist-label reversals or restored user posts. Response target then was seven working days.
Terrorist Content Analytics Platform → supplies URL-hash inputs subject to GIFCT’s own parameters → GIFCT Hash-Sharing Database
Taxonomy names TCAP but requires GIFCT inclusion parameters too. This filter defeats an inference that every TCAP label automatically enters HSDB.
Tech Against Terrorism → reported a March 2025 interface relaunch and later sharing activity → Terrorist Content Analytics Platform
Report publication anchor; March relaunch and other activity occurred at separately described times.
Reported by the cited source
December update reports added archive files and sharing with about six large technology companies. No actual recipient roster, audit or correction case supplied; cumulative and limited-period counts are not combined.
Microsoft → was named in TAT’s account of an AI-detection pilot → Terrorist Content Analytics Platform
2023-12-21 – 2023-12-21
Reported by the cited source
TAT’s 2023 review describes the Microsoft pilot. No Microsoft-side acceptance, deployed model version, financial value or completed validation result acquired.
Terrorist Content Analytics Platform → requires prior onboarding for authenticated API use → TCAP content-hash API — current public docs
Authentication introduction presupposes an existing onboarded TCAP or Archive account. It does not publish the current decision-maker, full eligibility contract or unrestricted access.
TAT Trusted Flagger Platform → advertises vetted partner referrals into the alerting workflow → Terrorist Content Analytics Platform
TAT describes categorized partner URL submissions with analyst/AI review and metadata for platform requests. Five-tier/125-plus-platform claims are advertised capabilities, not proof of universal integration or mandatory takedown.

2024 adapter imports source identifier/report date, group text, flags, URL and availability. This is the older URL-alert interface; it is not evidence of current content-hash deletion handling or ignored corrections.
