AI Coach: Think through what matters and commit with clarity

Crux is an AI decision coach for adults navigating complex choices. Unlike chatbots that tell you what to do, Crux draws out your thinking and then challenges it. Two modes: Crux - a structured coaching session (20-30 min) that maps options, stress-tests assumptions, and then helps you commit. Or Quick Crux — five sharp questions, ten minutes, real clarity. Built during a period of high-stakes personal decision-making. Grounded in research from Kahneman, Heath, and Klein. Free at launch.

I built Crux because I needed it. In March 2026, I was living in Doha with my family when the regional conflict between Iran, the US, and Israel escalated. Overnight, we were facing decisions with real stakes — financial, personal safety, family wellbeing — with no obvious right answer and multiple people affected by every option. I did what felt instinctive. I grabbed a pen and paper and drew out every option as a decision tree — mapping the branches, the trade-offs, what we'd gain and what we'd lose on each path. Then I called my dad. He listened, understood the complexity, and helped me prune the tree — cutting through the noise with the kind of objective perspective you can't give yourself when you're in the middle of it. He left me with two well-thought-out options and said: "Make your choice and send me a text with your decision and why. Write it down — because later, when the downsides feel real even though the upside is also there, you'll need to remember why you chose this." That moment — the clarity of committing in writing, with reasoning I could stand behind — gave me something I hadn't felt in weeks. Solace. So I built that flow and called it Crux. The decision tree became a five-stage framework grounded in research from Kahneman, the Heath brothers, and Gary Klein. The objective perspective became an AI coach that draws out your thinking first, then challenges it. And the text message became the commit step — where you own your decision with clear reasoning you can come back to. Crux now has two modes: a full structured session for decisions that deserve 20-30 minutes, and Quick Crux — five sharp questions for the ones you need to resolve today. Try it with a real decision. That's where it comes alive.

Refreshing to see AI tool that challenges you instead of saying what you want to hear. A question though, will chats be recorded or is it all local on our system?

@prateek_kumar28 Thanks Prateek — and great question, this matters to me a lot.

Everything stays local on your device. Decisions are stored in your phone’s encrypted storage, with optional Face ID lock on your decision history. Nothing syncs to a server, nothing is used to train models, no account required.

The only thing that leaves your device is the message you send to the AI for that turn (Gemini via Firebase) — and that’s not stored or tied to you. Once you close the session, only the summary lives on, and only on your phone.

Privacy was non-negotiable for me when I built this. The decisions people bring to Crux are some of the most personal things they’re working through.
