Three modes for problems a one-shot answer cannot solve — pick the depth each one needs.
Most structured first.
Trace any problem to its root — a guided investigation, not a one-shot answer.
Describe an outcome you don't understand — a failure, a result, a clinical finding. Inversion maps the plausible causes as a live branching graph, then works through it with you: it asks for the evidence that would confirm or kill each branch, updates the odds as you answer, and prunes dead ends until only the real, fixable causes remain.
You leave with the ranked root causes, a corrective action plan, and a report you can hand to anyone.
Define the expert you need — then it interviews you before it answers.
Tell it your situation, the kind of expert you need, and the decision you're facing. It takes that role and interviews you first — a handful of pointed, domain-specific questions — so the advice is built on your actual specifics instead of a generic explainer.
Your standard go-to chat.
Ask anything — it pulls in current sources when the facts matter. Free runs on a fast lightweight model; paid plans let you pick (Claude or GPT). No setup, no interview.
