How it works

From description to decision in seconds.

Describe your decision

Write your situation in plain language — a salary negotiation, a startup bet, a major purchase. The messier and realer, the better. No forms or templates required.

AI maps the branches

Claude extracts the decision nodes, chance events, and outcomes. Probabilities are estimated from real-world analogues and base rates — not made up.

Adjust and compare

A live decision tree shows expected value per branch. Drag the probability sliders to run your own scenarios. Save analyses and compare them side by side.

Built for clarity

Every feature designed to reduce noise.

Live EV calculation

Expected value recalculates instantly as you adjust probabilities on any outcome.

Probability estimates with rationale

Every probability comes with a cited analogue — e.g. 'Series A success rates suggest 60%'.

Risk & upside breakdown

Key risk factors and upside levers are surfaced for each branch, not just the top recommendation.

Scenario comparison

Save multiple analyses and compare them side by side to find the highest-EV path.
