Botster is a simulation testing platform that generates thousands of realistic, varied conversations to rigorously test your AI chatbots. It creates synthetic users with distinct objectives and personalities that interact with your chatbot across diverse scenarios, helping you uncover risks, edge cases, and performance gaps before going live.

How It Works

Botster generates AI-driven personas that produce test scenarios for your application, then iteratively prioritizes the highest-risk personas based on results.
  1. Configure — Define risk behaviors, product metrics, tone, and style
  2. Describe — Provide your chatbot description (like a mini PRD)
  3. Connect — Link your chatbot via API or knowledge base
  4. Simulate — Botster’s persona modeler creates realistic users with goals, personality, and skills
  5. Evaluate — The risk evaluation engine analyzes results and prioritizes high-risk personas

Core Concepts

TermDefinition
AI ChatbotThe chatbot Botster will test. You provide a connection (API endpoint or local server) and a description of its purpose and behavior.
SimulationA single test run. During a simulation, Botster generates personas that interact with your chatbot to create simulated conversations.
PersonaA synthetic user created during simulation. Each persona has unique goals, personality, behavior, and maintains state throughout the conversation.
ScenarioAn individual simulated conversation. Botster generates scenarios at scale during each simulation run.
MetricAn evaluation of chatbot performance on each scenario. You select which metrics to track during simulation.

Why Botster?

  • Scale your testing — Simulate thousands of user interactions that manual testing cannot practically cover
  • Rich persona modeling — Multi-dimensional personas generate realistic, diverse interactions across varied user types
  • High-quality test data — Automated generation produces comprehensive scenarios with authentic conversation flows
  • Catch issues early — Identify vulnerabilities and failure modes during development, before they reach production
  • Workflow integration — Fits into CI/CD pipelines. Export data to CSV, JSON, or your preferred evaluation tool
