§ how it works

we re-score every swipe against the rules in force the day you made it.

four hard problems most credit-card optimization tools quietly get wrong. we don't.

§ 01 · the pipeline

five stages. ~78 seconds.

every audit you run goes through these five stages. no human in the loop. no card on file. no money moved.

§ 02 · four hard problems

what most tools get wrong.

problem 1

rule drift

indian issuers change card rules ~1.5 times a month. the smartbuy 10x window, the atlas miles cap, the infinia annual fee — all moved in the past 18 months. most tools score against today's rules. we score against the rule in force the day you swiped.

12 RULE-CHANGES TRACKED · LAST 18M
problem 2

temporal correctness

when smartbuy 10x got capped at ₹15k on 01 jun, your may transactions kept their old (better) reward math. we keep the calendar straight. so what was true on jan 14 stays true for that swipe — forever.

EVERY TXN SCORED AGAINST ITS DATE
problem 3

honest range

one axis edge mile is not "₹0.40." it's ₹0.40–₹3.10, depending on what you redeem for. single-peg valuations lie. we show the range and the path that reaches the upper end of it.

RANGE > PEG · ALWAYS
problem 4

portfolio-aware redemption

the right card for one user is the wrong card for another. your three-card portfolio + your spending pattern + your existing miles pool → the optimal redemption path is specific to you, not to the comparison site's SEO target.
