Question 1

What does PolicyAsLanguage do?

Accepted Answer

PolicyAsLanguage takes a policy rule written in plain English and compiles it into idiomatic Open Policy Agent Rego, with generated pass and deny test fixtures verified against opa eval. It supports Kubernetes admission, infrastructure-as-code scanning, and application authorisation use cases in v1.0.

Question 2

Is PolicyAsLanguage free?

Accepted Answer

Yes - v1.0 is free, with no signup and no usage limit. Policies are not persisted: refresh the page and your work is gone unless you copied the Rego output.

Question 3

How accurate is the compilation?

Accepted Answer

v1.0 launches at 90.5% pass rate, independently measured at PolicyBench (https://policybench.dev/models/policyaslanguage.html). The PolicyBench leaderboard compares PolicyAsLanguage against frontier LLM baselines using a published methodology and a public corpus.

Question 4

What can't PolicyAsLanguage do in v1.0?

Accepted Answer

v1.0 doesn't support multi-record aggregation rules (e.g. 'no more than 5 admins per tenant'), stateful authorisation graphs (RBAC role hierarchies), or output formats other than Rego. Cedar, Kyverno YAML, and Cerbos targets are on the v1.1+ roadmap.

Question 5

Who built PolicyAsLanguage?

Accepted Answer

PolicyAsLanguage is built and maintained by Obsidian Black Ltd, a UK-based engineering company. It is the public face of Obsidian Black's natural-language-to-policy compilation pipeline.
