Your AI decision coach that captures what you’re deciding and why, flags cognitive biases before they take hold, and turns every outcome into a lesson. No templates. No forms. Just a conversation.
The researchers, authors, and investors who think clearest all share one habit: they write down what they believe before they know how it turns out.
The quality of your life is determined by the quality of your decisions.
We can’t control outcomes, but we can control the quality of our decision-making process.
If you don’t know why you decided, you can’t learn from how it turned out.
DJ folds three evidence-based practices into a single interaction — so you don’t have to change your workflow to improve your thinking.
Most learning happens after outcomes are known — which means memory rewrites the reasoning. DJ records what you believed and why at the moment of decision, before hindsight can corrupt it.
DJ knows 157 cognitive biases and watches for the specific patterns that distort your thinking. It only speaks up when your conversation has enough context to make it worth flagging.
When you revisit a past decision, DJ surfaces what you predicted, compares it to what happened, and helps you extract the update — without the usual self-serving narrative.
Most decision frameworks live in a book you read once. DJ lives in the conversation you’re having right now.
You don’t fill out forms. You talk to DJ like you’d think out loud — messy, partial, honest. DJ listens, asks the right questions, and structures the decision behind the scenes.
DJ doesn’t lecture you with a list of 157 biases. It flags one specific bias, one specific time, in one specific decision where it actually applies.
Six weeks later, DJ comes back. It shows you what you wrote then, asks what happened, and helps you close the loop — not to judge, but to calibrate.

A regular journal is freeform — you write what you remember, after the fact. DJ captures decisions at the moment they're made, structures them automatically, and comes back to surface what you predicted vs what happened. The difference is calibration: you can actually see if you're getting better.
No. The intent is that DJ lives in your workflow — you talk to it when you're weighing something, and it handles the structure. There's no 'log a decision' button you have to remember to press. You just have the conversation.
DJ has been trained on the 157 most common cognitive biases in decision-making contexts. It watches for patterns in your conversation — not to lecture you, but to surface a specific bias when the conversation has enough context to make it relevant. It's designed to feel like a smart friend noticing something, not a Wikipedia search.
Your decisions are private by default. We don't use your decision content to train models without your explicit opt-in. Decisions are stored encrypted at rest. You can export or delete everything at any time.
During private beta, access is completely free — no card, no timer. Join the waitlist and we'll send you an invite code when a spot opens. Pricing takes effect at public launch, and early members get advance notice before anything changes.
The Expert plan supports up to 5 team members with a shared decision library and group bias reports. Team-level calibration reports (how good is this team at predicting outcomes?) are on our roadmap for Q3.
