Cognitive training for the age of AI
Think for yourself
An AI that asks the questions instead of answering them. Built on the Socratic method to sharpen your reasoning, not replace it.
The problem
You're outsourcing your thinking more than you realize
Research suggests that chronic cognitive offloading — asking AI for answers, opinions, and decisions — quietly degrades your capacity for independent thought. Your prefrontal cortex gets less practice. Your reasoning atrophies. Clearus is the countermeasure.
A glimpse inside
Clearus catches the gaps in your reasoning
Logical fallacies and biases are surfaced so you can examine them.
Socratic questioning
One precise question at a time. You do the reasoning — not download someone else's conclusion.
Fallacy detection
Spots the logical errors in your reasoning with the precision of a philosopher. Names them only after you see them.
Bias mapping
Tracks the cognitive biases you fall back on across sessions. Knowing your patterns is how you stop being predictable.
Clarity scoring
Every exchange is scored on logical clarity. Watch your thinking sharpen session over session.
Built for the hard stuff
Stuck in a dilemma? Carrying something heavy? Looking for what truly matters to you? Let's build resilience.
Private by design
No ads. No trackers. No data selling. Conversations stay on your device. We store only what's needed for your account.
How it works
A structured conversation, not a chatbot
Bring what's on your mind
A decision, a conflict, a question you can't resolve. Start wherever you are.
Clearus asks, you reason
Short, precise questions that activate your thinking. Your reasoning is scored for clarity in real time.
See what your mind does
Fallacies and biases are surfaced across sessions. Over time, you see the patterns beneath your thinking.
"The easiest and noblest way is not to be crushing others, but to be improving yourselves."
— Socrates, as recorded by Plato in the Apology
