Platform
Test, simulate, and evaluate your AI agents.
Arklex Platform helps you validate AI agents before they interact with real users. Connect your agent, create realistic test scenarios, simulate multi-turn conversations, and evaluate performance with LLM-powered metrics — all from a single platform, with no custom testing infrastructure required.
Before Arklex. After Arklex.
One-off tests and scattered scripts become a repeatable evaluation pipeline for every AI agent.
Built for teams that build and operate AI agents
AI engineers
Catch regressions before deploying a new agent version.
QA teams
Structured, repeatable test coverage across the full range of user intents.
Product teams
A clear view of how well their agent serves users in realistic conditions.
No testing infrastructure or scripting experience required. Arklex handles scenario execution, conversation management, and evaluation scoring — all through the UI.
Why choose Arklex Platform?
Any agent, any framework
Connect agents built with LangChain, CrewAI, the OpenAI Agents SDK, or custom code through a standard Chat Completions or A2A endpoint. No SDK to install.
Realistic, multi-turn testing
Simulations play out as full conversations, not single-turn probes. Each simulated user follows a persona and goal across multiple turns, producing realistic transcripts.
LLM-judged evaluation
An LLM judge scores conversations on built-in and custom metrics, at both the conversation and metric level — so you can compare runs, track regressions, and prioritize fixes.
Custom metrics for domain-specific behaviors
Seven built-in metrics cover general quality. Define your own in plain language for the behaviors no generic rubric captures — versioned, reusable, and applied from the next run on.
Human-in-the-loop calibration
Dispute a judge score and add your own without overwriting it. Calibration tracks agreement per metric and links to each disputed turn, closing the gap with human judgment.
No infrastructure to manage
Arklex handles scenario execution, conversations, and evaluation scoring end to end. Run the workflow from the UI — no harness to build, no scripts to maintain.
