Pricing for AI decision evidence.
Plans scale by signed decision volume, retention, verification, exports, webhooks, and signing-key controls — not heavy synthetic-data generation.
Govern and Scale are built for high-risk AI evidence workflows that need Article 12 record-keeping support, long-term retention, dedicated keys, and audit evidence bundles.
