always
the right move
at checkout.
Your cards are full of rewards you earned and rarely collect. cashew makes the right call at every checkout, grabs the card-linked offers you'd never find, and keeps the dollars that are already yours. You just tap.
collect what's
already yours.
Your bank has cash waiting for you, 10% back at Lowe's or $5 at Dunkin', spread across pages you'd dig through one by one. cashew finds every offer on your issuer's page and activates them in a single click.
- One-click Save & ActivateNo clicking into 40 tiles. cashew activates them all, then tells you it's done.
- Surfaced on the right card at checkoutWhen you shop a merchant you have an offer for, cashew flags it on the card to use.
- Reads only what you can already seeOffers are read from your issuer's page while you're signed in. cashew never sees your bank login.
the right card's already there.
The moment you hit a payment form, cashew shows your highest-earning card and the dollars you'll earn. Tap once and it fills the number, expiry, and code. No tab-switching, no digging for your wallet.
Private by design. Even from us.
Most rewards apps want your bank logins. cashew doesn't. Your card numbers are encrypted on your device before they ever leave it, and we never sell your data.
Encrypted on your device. We store ciphertext we can't read.
Never asked for, never stored. Offers are read while you're signed in.
Only the site name leaves your browser, never page content or history.
We make money on referrals and Premium. We never sell your data.
Card details are encrypted on your device before they sync, opened by your passkey or a passphrase only you know. It's the same zero-knowledge model password managers use. Prefer to skip it? Use cashew with just card names and last-four. You still get every recommendation.
set it once. win every time.
No bank login required to start. Add the cards you carry and cashew handles the rest.
Start with just the card name. Optionally store full details in your encrypted vault to get one-tap autofill at checkout.
The Chrome extension detects checkout automatically, or search any merchant in the app. cashew finds your best card instantly.
Tap the card cashew recommends and it fills in the number, expiry, and code for you. Earn the most, every time, without thinking.
always know the move.
Not at a checkout? Type any merchant like Whole Foods, United, or your dentist, and cashew ranks your cards by the actual dollars each one earns there. No points math, no spreadsheets.
- every card you own, ranked by dollar value for that merchant
- spend math, welcome-bonus progress, and active offers factored in
You're spending real money to earn 1x.
cashew scans your cards for categories where you're consistently leaving money behind, totals the annual cost, and tells you exactly which card closes the gap.
- gas, earning 1x when a no-fee card earns 4x
- streaming, on a flat-rate card where 3x is available
- a dollar total, not a vague nudge: $106/yr here
never pay a fee on faith.
Before each renewal, cashew runs the math: rewards and credits you actually used, minus the fee. You get a verdict (keep, negotiate, or downgrade) and a script for the retention call.
- net ROI per card, so a $550 fee isn't a guess
- retention scripts for the cards worth fighting for
Track progress toward every welcome bonus, how much more to spend and how many days left, across everyone in your household.
cashew tracks issuer rules like Chase's 5/24, how many slots you have open and when the next card drops off, so you apply at the right moment.

Common questions.
The core product is free. We only recommend cards that increase your annual rewards. cashew may earn a referral fee when you apply for a card through us — always disclosed, and it never changes the ranking. Premium is optional and adds bank sync.
Only if you opt in to autofill — and even then, no. Card details are encrypted on your device before they sync, using a key only you hold (your passkey or passphrase). cashew stores ciphertext it cannot read. You can also skip autofill entirely and use just card names and last-four.
No. cashew works with just card names and last-four digits. Bank sync via Plaid is an optional Premium feature, read-only, and you can disconnect at any time.
When you visit a checkout page, the extension matches the site against cashew's merchant database and surfaces the card with the highest earn rate. Tap it and cashew fills in the card for you. Everything runs locally in your browser — no browsing history or page content is sent to our servers. Install it here.
The Chrome extension detects checkout pages by matching the URL against our merchant database, then shows your best card. On iPhone, the cashew iOS app includes a Safari extension. You can also use the web app: search any merchant (e.g. Whole Foods, United) and see which card to use.
No. When you open your issuer's offers page, the cashew extension reads the offers already there and activates them all in one click — then tells you how many it added. When you later shop a merchant you have an offer for, cashew flags it on the card to use. It only ever reads offers on pages you're already signed into; it never sees or stores your bank login.
Card-linked offers work across six issuers today: Chase, American Express, Wells Fargo, Bank of America, Citi, and US Bank. If a bank changes its page, we update cashew remotely — you don't need a new extension version.
A gap is any spend category where your best available card earns significantly less than the market maximum. If your best gas card earns 1x but a widely available no-fee card earns 5x, that's a gap worth closing.
Safari extension support is coming soon via the cashew iOS app. Firefox is not yet available but is on our roadmap.
Recommendations are ranked by projected dollar impact, not affiliate payout. cashew may earn a referral fee if you apply and are approved — always disclosed inline. A card without an affiliate deal will still be recommended if it's the right fit.
cashew tracks issuer application rules like Chase's 5/24 rule for everyone in your household. It shows how many slots you have open, when the next card drops off, and which issuers you're eligible for — so you can time applications strategically.
Yes. cashew supports household profiles — add up to 4 people, each with their own card set, bonus tracking, eligibility status, and fee ROI analysis. Everything rolls up into one household view.
optimize the game.
You already make good calls. cashew makes the right one every time you pay, keeps the dollars you earned, and never asks you to think about it.
