The system uses a backend engine to dynamically calculate cognitive metrics, track emotional variables like allostatic load and trust, and maintain conversational memory across sessions. A free tier is available for testing the simulation engine and mobile chat responsiveness.", "body_md": "I built Opendria to explore how generative AI can be coupled with cognitive and psychological state machines to create immersive educational experiences.\n\nInstead of using simple LLM wrappers, Opendria runs a backend simulation of brain, emotional, and cognitive states for 80 historical figures (like Einstein, Aristotle, Da Vinci, and Newton):\n\nCognitive Profiling: The backend dynamically calculates cognitive metrics (e.g., prefrontal cortex and temporal lobe scores) based on prompt sentiment and context.\n\nEmotional & Somatic Simulation: It tracks variables like allostatic load, trust, and visceral tension. If a character has high stress or low trust, their vocabulary, patience, and character reactions shift organically.\n\nConversational Memory: Uses structured persistence layers to track learned concepts and memories across sessions, avoiding LLM \"amnesia.\"\n\nI’ve set up a free tier for testing the conversation flows. I’d love to get the community’s advice and feedback on:\n\nThe Simulation Engine: How does the transition of emotional and cognitive states feel in the dialogue?\n\nUI/UX & Mobile: How is the mobile chat responsiveness?\n\nCharacter Depth: What other parameters or historical figures should be integrated into the engine?\n\nYou can check out the app here: [https://www.opendria.com](https://www.opendria.com) – Let me know your thoughts!", "url": "https://wpnews.pro/news/opendria-historical-ai-characters-simulating-brain-emotional-cognitive-states", "canonical_source": "https://dev.to/opendria/opendria-historical-ai-characters-simulating-brain-emotional-cognitive-states-30mc", "published_at": "2026-06-03 23:23:57+00:00", "updated_at": "2026-06-03 23:41:28.916082+00:00", "lang": "en", "topics": ["generative-ai", "ai-products", "ai-tools", "ai-startups", "natural-language-processing"], "entities": ["Opendria", "Einstein", "Aristotle", "Da Vinci", "Newton"], "alternates": {"html": "https://wpnews.pro/news/opendria-historical-ai-characters-simulating-brain-emotional-cognitive-states", "markdown": "https://wpnews.pro/news/opendria-historical-ai-characters-simulating-brain-emotional-cognitive-states.md", "text": "https://wpnews.pro/news/opendria-historical-ai-characters-simulating-brain-emotional-cognitive-states.txt", "jsonld": "https://wpnews.pro/news/opendria-historical-ai-characters-simulating-brain-emotional-cognitive-states.jsonld"}}
