Comparing your full cart across the metro’s biggest chains
The same cart can cost 20–40% more one aisle over.
US households spend roughly $5,700 a year on groceries, and prices swing week to week across the stores within a short drive. Checking every chain by hand is impossible — so most of us just guess, and quietly overpay.
Karti owns the one moment that decides it all: after you know what you need, but before you’ve picked where to go.
Same 14‑item list · today
Three steps. About sixty seconds.
Build your list once
Type it, paste last week's, or rebuild a past trip. Karti tracks a real price for every item across each chain — no scanning shelves, no guesswork.
See the cheapest store
One tap ranks every nearby store by what your whole cart actually costs — with the savings spelled out and an honest nudge when a closer store is barely more.
Prove it with your receipt
Snap your receipt after you shop. Karti checks its prediction against what you paid, builds your personal price history, and gets sharper every trip.
A grocery tool that shows its work.
List‑first, not store‑first
Start from what you need. Karti finds the store — instead of locking you into one before you know the price.
Whole‑cart math
We compare the total cost of your entire run, not a handful of cherry‑picked loss leaders.
Honest by default
“Walmart is only $1.83 more.” When a closer store is barely pricier, we say so. No manufactured urgency.
Receipts that pay off
Snap a receipt to confirm the prediction and quietly build a price history that’s yours.
Made for Austin
Deep, fresh pricing on the chains you actually drive to across the Austin metro — not a thin national average.
Calm, not gamified
No streaks, points, or confetti. The savings are the reward. An adult tool for adult shopping.
Most apps promise savings. Karti proves them.
Snap your receipt and Karti reconciles it against the prediction, line by line. You see exactly how close it was — and when something rang up differently, the price updates for everyone near you.
