How Pikt pikts your best card
For each purchase, Pikt reads the store type and compares the reward rate, bonus categories, and active promotions across every card in your wallet, then surfaces the single card that earns the most. The pick is recomputed per transaction, so it adapts as your bonus categories rotate or caps fill up.
Free vs Premium
Free includes the purchase simulator and best-card recommendations across the full card catalog — no bank linking required. Premium adds Plaid card linking, best-card selection across your real wallet, test-a-purchase demo, confirmed savings history, and wallet analytics. Compare plans →

Setup & cards
Linking cards with Plaid
On Premium, connect accounts through Plaid's read-only flow. During this personal preview, use the demo credentials (
user_good / pass_good) — never real bank logins. Pikt stores only masked references, never raw card numbers.Using Pikt where you pay
Pikt never issues a card — it carries the decision, not the dollars. Get started from the Pikt overview page. Online, the Pikt Checkout browser extension recognizes the store and auto-fills your best card at checkout. In-store, Pikt Nearby names the best card on your lock screen as you walk in and can prompt you to set it as your Apple Pay or Google Pay default.
Keeping cards current
Pikt flags any linked card that has expired or expires within 60 days so picks stay accurate. Manage or remove cards anytime in Wallet.
Data
Data & privacy
Your savings history
Premium keeps a running history of confirmed savings — the extra rewards earned by following Pikt's recommendations versus a flat-rate baseline. Each purchase adds a line you can audit and export.
Your data & privacy
Pikt connects through bank-grade, read-only data access and never moves money or stores raw card numbers. You can export your data or delete your account at any time from Settings. Read the Privacy Policy →
