Build, Test, and Scale Conversational AI Personas
Persim is a prompt authoring and evaluation platform designed to bridge the gap between model training and human-like interaction.
The QA Layer for Your AI Personas
Most teams building conversational AI simulations face a “black box” problem. Persim provides the lighting. We've built the standard for evaluating how your personas behave in high-stakes environments, from patient simulations to corporate training.
EdTech & Medical CAI Teams
Validate pedagogical accuracy and clinical bedside manner in virtual training patients.
AI & Prompt Engineers
A specialized workbench for rapid iteration, prompt versioning, and stress-testing edge cases.
Enterprise L&D
Scale soft-skills training with consistent, high-fidelity AI roleplayers that never break character.
A Complete Platform for Persona Intelligence
Persona Authoring
Deep narrative controls and personality trait weighting for consistent model behavior.
Domain Contexts
Inject RAG-based knowledge bases to ground your personas in specific factual domains.
Automated Test Runs
Run thousands of simulated conversations in parallel to detect persona drift.
Dual Evaluation Modes
Automated LLM-as-a-judge scoring paired with deep human-in-the-loop review tools.
Multi-Model Ready
Switch between GPT-4, Claude, and Llama 3 to see which model performs best for your persona.
Export & Reporting
Comprehensive PDF and JSON reports for compliance, training, and engineering hand-offs.
The Persim Workflow
Author
Define the core backstory, language style, and emotional constraints of your AI agent.
Test
