Assessment
Enterprise platform: low
Reasoning: An enterprise generative AI platform with its own models. The privacy policy itself rules out training on inputs and outputs, which is rare among vendors that also publish it in marketing. Sold under contract with US processing by default; region is a deployment question.
Flags: US processing by default · Assessed 2026-09-16. The assessment is Unseen's; the terms above are the vendor's.
