Why This Matters

Prior is a consumer-facing forecasting tool that packages LLM-style research and scenario simulation into calibrated probability reports for anything from sports to markets to personal decisions. It signals a shift from chat assistants toward accountability-oriented AI products, with a per-user accuracy record and prediction archive. Its tiered pricing, topping out at $499/month for unlimited forecasts, tests how much consumers will pay for probabilistic guidance that explicitly disclaims being financial, legal, medical, or betting advice.

Key Takeaways

Prior gathers context via follow-up questions, researches public web data, and returns a calibrated probability with weighted scenarios, key drivers, flip conditions, and suggested actions.
Pricing spans a free weekly prediction with no account to Standard ($29), Max ($99), and Ultra ($499) tiers; accounts add a prediction archive and accuracy record.
The company disclaims liability and says it offers no financial, medical, legal, or betting advice, leaving all decisions to the user.

Worth a Look

Prior helps you anticipate anything: sports, markets, decisions, even the messy personal stuff. It pulls context, runs simulations, and gives you the sharpest weighted outcomes. Our goal is to create the most powerful predictive intelligence in existence.

What is Prior?

Prior is a predictive intelligence platform built by Prior Software Inc. It helps people anticipate the outcome of future events and decisions — including sports, financial markets, business choices, and personal questions.

How does Prior work?

You ask any question about a future event. Prior asks short follow-up questions to gather context, researches current public information on the web, reviews your relevant past predictions, and then produces a single forecast report containing a calibrated probability, weighted scenarios, the key drivers behind the prediction, the conditions that would flip the outcome, supporting context, and suggested actions.

What does Prior cost?

Free visitors get one prediction per week with no account required. Paid monthly plans are Standard ($29, ten predictions per week), Max ($99, thirty predictions per week), and Ultra ($499, unlimited predictions). Accounts include a personal prediction archive and an accuracy record across resolved forecasts.

Is Prior financial, medical, legal, or betting advice?

No. Prior is proprietary research software. It does not provide financial, medical, legal, or betting advice, and it accepts no liability for decisions made from its forecasts. Users make their own decisions.
