What it does
Stop guessing which credit card to swipe. OptimalSwipe tells you the best card for every purchase, privately and on-device. Your cards and transactions live in your private iCloud Drive. Recommendations run locally using smart built-in rules and a fast Apple Shortcut. Trigger both from the app screen, or run the Shortcut directly for instant suggestions. No bank logins. No servers. Installable as a PWA on desktop and iPhone. Maximize points or cash back. Early, opinionated, privacy-first.
OptimalSwipe is a local-first, privacy-focused smart credit card manager that helps you maximize rewards without sharing your bank data.
Add popular cards like Amex Gold, Sapphire, or Bilt in one tap. Define your card's rewards. This template will be saved to your library for future use. OptimalSwipe stores all data directly in your browser's secure database. Depending on your browser, this data can be in one of two modes: Tip: If you see "Best Effort," try choosing "Add to Home Screen" (PWA) to help the browser grant Persistent status. Regular backups are always recommended. Link a file on your device (or cloud). Every change you make is instantly saved. Note: This feature is currently supported in Chrome, Edge, and Opera desktop. Safari and Mobile users should use manual backups or export/import. Save your data to iCloud…from karthikkadambi.github.io

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
