> Open-source swarm-intelligence simulation engine (83k+ GitHub stars, AGPL-3.0): upload a product idea, pitch deck or MVP and it builds a world of AI personas with their own backgrounds who react to it and argue on a simulated social network, then writes a report on why they liked or hated it. You can chat with any persona.
