How it works

From document to prediction in minutes

No setup. No data science degree. Just upload, describe, and watch the simulation unfold.

01

Upload your seed

A news article, financial report, policy draft, or even a novel. ThousandMinds extracts the key entities and relationships.

02

Agents come alive

Thousands of AI personas are generated — each with a unique personality, memory, and behavioral logic based on your content.

03

Watch them interact

Agents post, argue, form opinions, and influence each other across two simulated social platforms simultaneously.

04

Read the forecast

A detailed prediction report emerges from the collective behavior — not from one model's guess, but from emergent crowd dynamics.

Everything that involves humans, predicted

FAQ

Common questions

Is my API key safe?
Yes. Your API keys are encrypted at rest using AES-256 and never shared with third parties. All connections are secured via HTTPS/TLS. You can delete your key at any time from your dashboard.
What LLM providers are supported?
ThousandMinds works with any OpenAI-compatible API — including OpenAI (GPT-4o, GPT-4o mini), Alibaba Qwen, and others. We recommend GPT-4o mini for cost-effective simulations.
How accurate are the predictions?
ThousandMinds surfaces plausible scenarios based on emergent agent behavior — not hard probability estimates. Think of it as a structured scenario exploration tool, not a crystal ball. The value is in seeing dynamics you might otherwise miss.
How much will the simulation cost me in API fees?
A typical simulation with 100 agents and 20 rounds costs roughly $0.50–2.00 using GPT-4o mini. Larger simulations with 1,000 agents cost more. We recommend starting small to calibrate your use case.
Can I cancel anytime?
Yes, absolutely. Cancel your subscription any time from your dashboard with one click. No questions asked, no hidden cancellation fees.
