How it works

Turn messy thoughts into clear decisions — in a repeatable, step-by-step way.

  1. Tell it your situation: Paste notes, context, constraints, and what your decision goal.

  2. CoThinker structures your reasoning: It separates facts vs assumptions, clarifies options, trade-offs, risks, and next steps.

  3. You leave with an actionable output: A decision, a plan, a summary, or a reusable template — clear and ready to execute.
