AI Reasoning Coach
Not a prompt over a model. A reasoning framework — applied consistently to the situations where structure matters most and generic AI helps least.

How it works
The value delivered is not information. It is the imposition of a reasoning structure onto a situation you cannot organise alone.
Paste rough notes, context, constraints, and your decision goal. No preparation needed — raw, messy input is the starting point, not a problem.
It names the structural cause of your block before proposing any solution. Then separates facts from assumptions, clarifies options, trade-offs, risks, and measurable STOP/GO thresholds.
A decision, a plan, a structured summary, or a reusable reasoning template — honest, clear, and ready to execute. No generic advice. No validation of what you want to hear.
Use Cases
Sunk costs, avoidance, cognitive overload. CoThinker names the bias actively at play before proposing any solution — the territory where standard AI is weakest.
Irreversible decisions with a deadline. CoThinker reframes the problem from "decide yes/no" to "determine if the decision is ready to be made."
Too many open loops, hard resource constraints. CoThinker delivers specific allocation — not "balance A and B" — with measurable STOP/GO thresholds for each path.
"CoThinker is not a prompt over a model. It is a reasoning product. The distinction is observable in the outputs, reproducible across different problem types, and resistant to replication by standard LLM usage."

FAQ
A reasoning framework with a conversational interface. It applies the same reasoning principles — mechanism identification, facts vs. assumptions, risk with mitigation, measurable thresholds, actionable next step — consistently across any type of problem.
A well-prompted LLM can approximate CoThinker's output quality — if you know how to prompt for mechanism identification, fact/assumption separation, and measurable thresholds. CoThinker's value is that it eliminates that requirement. You don't need to know how to prompt. The framework does it.
No. CoThinker does not replace your judgment. It imposes a reasoning structure onto situations you cannot organise alone — so you can decide with clarity, not just confidence.
High-stakes, emotionally complex scenarios where your own cognitive biases are part of the problem being solved. Decisions under time pressure, resource constraints, incomplete information, or avoidance. The territory where generic AI produces validation instead of structure.
No. Paste rough notes, thoughts, or context as they are. CoThinker produces the full analysis first — then identifies the single data point that would change everything. The cognitive load stays with the framework, not with you.
A structured, honest, actionable output: a decision, a plan, a summary, or a reusable reasoning template. Always with a concrete next step and a closing diagnostic question designed to make your implicit decision criterion explicit.
Trust & Transparency
An independent reasoning coach and decision-support system designed to help structure complex thinking. It provides cognitive support, not professional, legal, medical, or financial advice.
CoThinker does not replace human judgment. It does not make decisions on your behalf and should not be used as a sole source for high-stakes decisions.
