Description

Plurai Simulation is an AI-powered testing platform that places an AI agent inside a simulated world so developers can find where it breaks and how to fix it before real users do.

It reads the agent as built, maps its knowledge bases and decides what stays live and what gets mocked. The agent then meets synthetic personas, reads synthetic documents and calls mocked tools, APIs and databases, with no integration work needed from the team.

Each run happens in an isolated sandbox that never touches production, and the world resets to the same state every time, so teams can measure how consistently the agent behaves across runs.

Plurai models what an agent can do as a probabilistic flow graph and generates scenarios to cover it, including hard personas that push back and probe policies, and the tasks most likely to cause failures.

Key features include root-cause analysis that separates real agent bugs from noise, ranked findings that point to the exact code location, fixes that are applied and re-verified, evaluations that check what the agent actually did rather than what it said, and a regression loop fed by production traces.

It runs inside the coding agent a team already uses, installed as a plugin for Claude Code, GitHub Copilot CLI and OpenAI Codex, with Cursor support listed as coming soon. It can be used interactively or in CI, and scores come with their reasoning in the repo and in existing observability tools.

Pricing: a Free plan includes a one-time allowance of 12,300 credits, 2 agent setups, 7 scenarios, 3 runs and 10 sandbox hours. The Base plan is 60 US dollars a month and the Business plan is 210 US dollars a month, each with monthly credits and pay-as-you-go rates. Demos are also available.

It is suited to AI engineers and product teams building customer-facing or enterprise agents who want structured, repeatable testing instead of hand-written test cases.
