Key findingsclick a row for the evidence

✓Consistent no-training and limited-retention position across marketing, privacy and contractStrong

The trust page, the consumer-facing privacy policy and the DPA all say the same thing: customer inputs and outputs are not used to train WRITER models, data is kept only as long as needed to provide the platform, customers can set an automated deletion schedule, and the DPA adds purpose limitation, no sale/share, and return-or-delete on request. The position is backed by a stated ISO/IEC 42001 AI management certification, a named CISO, a risk-based AI-governance program and annual third-party penetration testing.

A no-training commitment that appears in the contract (not only on a marketing page) is enforceable, and consistency across three document types reduces the chance that an enterprise buyer is reading a position that only applies to one tier.

!Inference and model-routing subprocessors sit behind a 'Palmyra-only' narrativeGap

WRITER positions the platform around its own Palmyra LLMs, yet the October 2026 subprocessor list names OpenRouter, Baseten and Parasail under the generic purpose 'Infrastructure'. These are model-hosting and model-routing services, which implies that at least some requests may be served by, or routed to, third-party hosted models. The list does not say which models or upstream model providers sit behind these entries, or whether prompts reach them.

If customer prompts are routed through OpenRouter to third-party model providers, the data recipients, retention and training commitments of those providers become part of the buyer's exposure, and the ISO 42001 scope may not cover them. This is an inference from the vendor names, not a disclosed fact, so it should be confirmed in writing.

Question for vendor: Which models and model providers can serve requests on the platform, under what circumstances are requests routed to OpenRouter, Baseten or Parasail, and do any third-party model providers receive customer prompts or outputs?

!Certifications are vendor-claimed and two are mislabelledGap

SOC 2 Type II, ISO/IEC 27001:2022, 27701:2019 and 42001:2023 are asserted on the trust page and in the DPA security exhibit, with a trust center and a SOC 2 report available on request, but no certificate, auditor, scope statement or validity date appears in the collected documents. The trust page also claims 'certifications for HIPAA Type 1 and PCI compliance': HIPAA has no certifying body, and the PCI DSS level, scope and assessor are not stated.

ISO 42001 is the most assurance-relevant claim for an AI platform and its scope (which products, which sites, which model development activities) determines what it actually covers. Mislabelled compliance claims on the same page lower confidence in the precision of the others until the certificates are sighted.

Question for vendor: Please provide the ISO/IEC 42001, 27001 and 27701 certificates with scope statements and certification body, the current SOC 2 Type II report, and clarify what is meant by 'HIPAA Type 1' and the PCI DSS attestation level and scope.

Vendor publishedWorld-class enterprises trust WRITER ↗retrieved Oct 20, 2026
“We also maintain certifications for HIPAA Type 1 and PCI compliance and adhere to our obligations under global privacy laws.”
!'Zero data retention' marketing versus criteria-based contractual retention and open-ended incident noticeGap

The trust page describes a 'zero data retention approach', while the DPA's binding retention term is criteria-based ('the period of time necessary... to provide the Platform... and/or in accordance with applicable legal requirements') with no fixed window; deletion relies on the customer configuring a schedule or making a written request. The incident clause commits to notice 'without undue delay' but sets no hour-based target. The consumer privacy policy separately reserves broad use and onward disclosure of de-identified data, which is scoped to individual accounts and not to enterprise DPA customers.

Buyers relying on 'zero retention' should understand that the contractual position is the ordinary necessity standard, and that the default retention period, the behaviour of the deletion schedule, and the notification timeline are things to pin down in the order form rather than assume.

Question for vendor: What is the default retention period for prompts, outputs and uploaded files when no deletion schedule is configured, what is the maximum notification time for a confirmed Security Incident, and does the de-identified data clause in the privacy policy apply to any data from enterprise accounts?

Evidence

!No public model documentation or evaluation results in the collected materialGap

Beyond a pointer to Stanford HELM rankings for Palmyra and a description of an in-house toxicity classifier, the collected documents contain no model card, system card, evaluation results, red-teaming summary or EU AI Act risk classification; bias and toxicity methodology documentation is offered only on customer request, and the EU AI Act statement is a commitment to comply while obligations are still being evaluated. ai_system_description, model_provider_transparency and testing_and_evaluation are therefore assessed as partial rather than covered; none of the ten domains is not_applicable because WRITER hosts the models and sits in the request path.

ISO 42001 certification does not substitute for published model documentation; a buyer deploying agents on regulated workflows needs the evaluation evidence and AI Act positioning to complete its own impact assessment.

Question for vendor: Can WRITER provide model cards and evaluation/red-teaming results for the Palmyra models in production use, and its EU AI Act role and risk classification for the platform?
