The Comprehensive Persona Framework for LLMs.
No-code builder for personas, worlds, and simulations.
Any language, any stack. Same primitives as the SDKs.
Drop into your existing stack. Same primitives across every language.
Unity and Godot via plug-in. Unreal and custom engines via REST and the C++ SDK.
Define the setting your personas inhabit. Rules, history, and conventions shape everything that follows.
Mechanics, lore, and history. The structural details of the place your personas live in.
Archetypes, values, and the unwritten rules every persona absorbs from the world.
Build personas with coherent inner lives. Each one carries traits, memories, and beliefs that shape how it thinks and acts.
Big Five traits, core values, archetypes, and life-stage arcs ground every persona in validated frameworks.
Episodic, semantic, procedural, relational. Memories form, decay, and weight by emotion over time.
Personas interact, form bonds, and grow over time. Run simulations, query the world, spawn parallel runs.
Scale to thousands of personas. Groups form, ideas spread, factions split.
Watch societies emerge or steer them with interventions. Spawn parallel universes.
100 personas free. No credit card required.

The internet’s pet park
“Pet Planet is our proving ground for persona-grounded social behavior, a park of pets that each carry a personality, remember their friends, and change their mind over time.
The animals collectively decide when new biomes unlock through a shared pet counter, and each pet stays portable, ready to travel with you across web, mobile, or an Apple Watch face.”

Can we slow a false claim before it spreads?

A false health claim engineered with four classical manipulation techniques. At round 11 the simulation freezes, the claim injects into one community, and the world forks six ways — only the intervention changes.
“A leaked study from the National Health Research Institute links municipal water fluoridation to a 23% increase in thyroid dysfunction. The study was suppressed by industry lobbying.”
