Imagine being able to run a simulation of the internet before you post anything to it. MiroShark lets you drop in any document — a business idea, a controversial take, a product announcement, a policy change — and instantly spawns hundreds of AI characters who react to it exactly like real people would: posting, arguing, changing their minds, and even betting on outcomes in a prediction market. You see who gets angry, who becomes a fan, how opinions shift over time, and where the conversation goes off the rails — all before any of it is real. It's like having a focus group, a Twitter firestorm, a Reddit thread, and a prediction market all running simultaneously in a private sandbox you control. Whether you're testing a startup pitch, stress-testing a controversial idea, or just curious how the world would react to something — MiroShark shows you the reaction before you pull the trigger.
