DriveDecision is a decision engine powered by Quirk AI that helps consumers determine whether buying or leasing a vehicle is the financially safer option based on their personal situation.
Unlike generic calculators, DriveDecision focuses on risk, cash-flow stress, and long-term impact, not just monthly payments.
Car buying decisions are emotionally charged, expensive, and easy to get wrong.
Most tools:
- Show numbers without context
- Focus only on monthly payment
- Avoid making a clear recommendation
DriveDecision by Quirk AI provides a clear verdict with an explanation that answers:
“Given my situation, should I buy or lease this car?”
-
The user enters:
- Basic financial profile
- Buy scenario details
- Lease scenario details
-
A deterministic decision engine calculates:
- Total cost of use
- Monthly obligation stress
- Downside risk if income drops
- Exit flexibility
-
An explanation layer translates the results into:
- Plain-language reasoning
- Risk flags
- A confidence score
Quirk AI does not invent numbers or predict markets.
It explains verified calculations.
- Decision clarity over dashboards
- Deterministic math before AI
- Risk awareness over optimism
- Minimal inputs, maximum insight
- Framework: Next.js (App Router)
- Language: TypeScript
- Backend: Next.js API routes
- Quirk AI: LLM API for explanations only
- Payments: Stripe (planned)
- Hosting: Vercel

decisionEngine.tscontains all deterministic decision logic- Quirk AI layers never modify core calculations
This project is in active development.
Current focus:
- Implementing buy vs lease decision formulas
- Stress and risk scoring
- Validating outputs against real-world scenarios
UI and monetization come after correctness.
DriveDecision provides educational decision support only. It is not financial, legal, or tax advice.
- Complete deterministic buy vs lease engine
- Add AI explanation layer
- Add pricing and paywall
- Launch web MVP
- Expand to additional decision types
