What the vendor documents
Recorded from the vendor's own trust, privacy and terms pages. "Not disclosed" means we found no public statement, not that the control is absent.
What the public documentation states
Merlin's Alchemy page describes an e-discovery and investigation system that lets users ask questions across document collections and receive sourced answers, timelines, summaries and review reports with citations. The terms describe the application as web-based software for document management, discovery, investigation workflow automation, data sharing, collaboration, case management, claim management and deal management. The terms refer to external AI service providers but do not name them; they require those providers to keep prompts and responses confidential and not use them for training. The security page states that Merlin can deploy client environments in specific AWS regions, a client's private AWS environment or a FedRAMP environment, and that each client has isolated infrastructure. It states SOC 2 Type II certification and ISO 27001 planned for 2026. Pricing is described as usage based without a list price. Merlin states a 98% privilege-call figure and publishes a ReviewPartner sampling and validation method.
In the vendor's words
“pay only for what you actually use”
“do not use input prompts and output responses to train”
“deploy client environments in specific AWS regions”
“ReviewPartner runs a formal validation step against a fresh sample of documents”
Not disclosed on public pages
"Not disclosed" records that no public statement was found where we looked, on the date shown. It does not assert that the control, term or figure is absent.
Not published on the pages we read on 2026-09-06: named AI model providers, a sub-processor list, list price, minimum term, SSO/SAML, zero retention and ISO 42001. Procurement and DPIA reviewers would normally ask for those details to record client-confidentiality safeguards, region-specific processing, SRA/ABA supervision duties and GDPR Art. 28 processor commitments.
Questions to put to the vendor
- Which external AI service providers process prompts and responses for Alchemy, and in which AWS or FedRAMP regions?
- Can Merlin provide the current sub-processor list and the DPA terms that govern client collections?
- Does any Alchemy configuration provide zero retention for prompts, responses or extracted document text?
- What sample design, reviewer role and matter type support the stated 98% privilege-call figure?
