◆ Workflow

How the engine works

Three deterministic stages. From profile capture to a ranked recommendation set in under a second.

STEP 01
01

Profile capture

Five structured questions: credit range, income, category spend, goals, preferences. ~2 minutes.

STEP 02
02

Match & score

Engine computes fit across 4 weighted factors and estimates usable first-year and ongoing value.

STEP 03
03

Ranked output

You get 3–5 cards with full reasoning, pros/cons, projected rewards, and direct application links.

◆ Infrastructure

Built different

Not another comparison site stuffed with top-affiliate-payout cards. A real engine built for people who optimize.

01 · Engine

Deterministic scoring

A transparent 4-factor match algorithm (spend, goals, fees, eligibility) — no black box, no affiliate bias.

02 · Value

Expected usable value

We estimate usable rewards from category spend, likely credits, fees, and conservative redemption assumptions.

03 · Coaching

Score-lift playbook

Personalized credit improvement steps ranked by lift potential — utilization, age, inquiries, mix.

04 · Data

Plaid-grade integrations

Optional read-only bank connection auto-computes 90-day spend. AES-256 encryption, never stored plaintext.
