AI governance, testing, and observability for regulated enterprises
Dozens of pre-built evaluations cover quality, safety, security, and performance, with LLM-as-a-judge scorers, session-level metrics, and support for writing your own custom tests against your own data.
Import a repository and run evaluation suites automatically on every change, benchmark each iteration, and block releases when a metric regresses beyond the threshold you define.
Trace every request through multi-step agent workflows, including tool calls and retriever steps, with token counts, latency, cost per request, alerting integrations, and subpopulation analysis.
Register each AI system with an owner, purpose, data sensitivity, and risk tier, score inherent risk across multiple dimensions, and move systems through staged approval gates before they reach production.
Build and share random generators for free with lists and simple code
Define items as lists and let Perchance pick randomly, producing names, items, prompts or full paragraphs.
Customize how your generator looks and behaves with standard web markup, styling and scripts.
Publish generators instantly so anyone can open and use them from a shareable page.
Browse and reuse generators created by the community, from RPG tools to story prompts and AI apps.
