Simulation and evaluation platform that tests AI agents in sandboxed digital twins, finds failures before users do, and closes the fix loop.

What is Plurai?
A simulated world that makes your agent improve on every run
Plurai is the recursive self-improvement layer for AI agents. Instead of judging an agent by its chat logs, Plurai builds a digital twin of the agent's world — synthetic personas and documents plus mocked tools, APIs and databases — and runs it in sandboxes that never touch production.
One command in Claude Code, Codex or GitHub Copilot sets up a simulation that probes real behavior and edge cases, finds the agent's worst bugs before users do, and hands each bug to a coding agent with a reproduction conversation to fix, retest and submit. Evaluations and synthetic datasets are generated for your own use cases, and sub-100ms guardrails intercept out-of-bounds behavior live in production.
Plurai is free to start, with paid plans for individuals and teams that need more simulations and collaboration.

Plurai Key Features
Simulation testing
Build a digital twin of your agent's world with synthetic personas, documents and mocked tools in sandboxes that never touch production.
Evals and synthetic data
Generate measurable evaluations and synthetic datasets tailored to your own use cases.
Real-time guardrails
Sub-100ms guardrails intercept out-of-bounds behavior in production before it reaches users.
Fix loop
Every bug ships with a reproduction conversation so a coding agent can fix it, retest and submit.
Continuous improvement
Every run makes the agent sharper, with teams reporting far fewer failures over time.

Common questions
Plurai FAQs
Is there a free plan?
Yes. The Free plan lets you explore the product, connect one agent and run a small number of simulations.
How does the 7-day trial work?
The trial ends automatically when it expires and never charges you. You can also stay on the Free plan instead.
What is the difference between tokens and credits?
Tokens cover model usage only, while simulation credits cover the full job: running simulations, evaluations and data generation.
Do unused credits roll over?
No, credits do not carry over to the next month. You can upgrade, downgrade or cancel at any time.
