Open-source tool launches hundreds of AI agents to simulate social media reactions
Developers have released MiroShark on GitHub, a system that spawns hundreds of AI agents to mimic reactions on simulated Twitter, Reddit and prediction markets. Users feed in press releases, news headlines or what-if scenarios, with agents posting, arguing and trading hour by hour. The tool runs full simulations in under 10 minutes for as little as $1 using cheap presets, or up to $3.50 for advanced ones. Features include chatting with individual agents, forking timelines mid-simulation, injecting breaking news and generating cited reports. Setup uses an OpenRouter API key and a Neo4j database.
Solopreneurs testing niche ideas or positioning statements faced a brutal loop: craft a UVP, blast cold outreach, endure silence or ghosting, retreat to no-code tweaks with zero validation. MiroShark breaks that by crowdingourcing simulated crowd reactions from hundreds of grounded agents pulling real data, revealing in minutes if a market gap exists or if pitches land flat. This creates synthetic social proof early, letting beginners spot hungry ICP signals without burning leads or savings on unproven offers.
Analysis
This is your ticket out of builder's avoidance and into consultative positioning – ditch website fiddling and simulate your top niche ICP as a product launch to see if agents engage or yawn. Install MiroShark with your OpenRouter key today, run that one scenario, and pivot ruthlessly if reactions signal saturation.
