Frequently asked questions
Who is this for?
Anyone at work who makes calls that matter. Managers, PMs, engineers, analysts, marketers, ops. If you have prioritized a backlog, run a hard meeting, or lost a weekend to a decision you kept putting off, this is for you.
How is this different from reading a book?
Books explain. deciMate makes you practice. You run realistic scenarios from your kind of work, get AI feedback on how you actually reasoned, and build the habit through reps. Reading gives you vocabulary. Practice gives you skill.
Do I have to pay to start?
No. Create an account, take the assessment, start practicing for free. Full access unlocks every framework and unlimited scenarios for one $15 payment.
Is it a subscription?
No. Pay $15 once. Keep it for life, updates included. No recurring charges, no cancellation dance.
How much time does it take?
Five minutes a day is enough to build the habit. Most lessons and drills fit in a coffee break. You set the pace.
Which frameworks does it cover?
Six: System 1 and 2 thinking (Kahneman), Recognition-Primed Decision-making (Klein), the OODA loop (Boyd), debiasing techniques, the Critical Decision Method, and team decision-making.
