Your cards became coupon books.

Cards now pay you back through dozens of separate credits on different clocks — monthly, quarterly, semi-annual, anniversary-year — and it's not just premium cards anymore. The value is real, but you only collect it by doing homework every month, forever. Issuers call the credits you let expire breakage, and they price it in.

separate credits on a $795 Sapphire Reserve — five of them monthly.

different reset schedules on a $895 Amex Platinum's twelve credits.

$0

is what an unused credit is worth the day after it resets. No rollover, no grace period.

Two minutes to a managed portfolio.

1
Add your cards

Search a catalog of 130+ cards and tap the ones in your wallet — even retired ones. No bank login, ever.

2
Choose what to track

Every credit comes pre-loaded. Keep the ones you'll actually use, drop the rest — your dashboard stays signal, no noise.

3
See what expires first

Credits arrive sorted by deadline — this month, this quarter, this year — so the most urgent ones are always on top.

4
Tap as you go

Mark a credit used or unused in one tap, or log a partial amount and baku keeps the running balance. Periods roll over on their own.

Deadlines, managed

Other tools tell you whether a credit was used. baku tells you what expires soonest and what to do about it — this month, this quarter, this year. Periods roll over by themselves. Nothing to maintain.

Private by design

baku never connects to your bank. No credentials, no card numbers, no transactions — only what you choose to share: the cards you hold and the credits you've used. There's nothing sensitive here to breach. That's a feature, not a gap.

You're the customer, not the product

baku makes money one way: a subscription you pay. No affiliate links, no "apply for this card" wall, no selling your data to issuers. That's the point — when the banks aren't paying us, our only job is getting you every dollar back.

A family office for your wallet.

The ultra-wealthy have portfolio managers. Now you do too. Because baku knows your cards, fees, anniversaries, and what you actually redeem, it can answer the questions that drive real money decisions:

Is this card paying for itself?

Credits redeemed vs. annual fee, per card, per year.

Renewal coming — what now?

The right moment to call for a retention offer, with your numbers in hand.

Keep, upgrade, downgrade, or cancel?
