What it does
Stop chasing friends for money. Expense Matrix Splitter uses a unique grid-based approach for complex group expenses. Features advanced custom split logic ($ and %), local file saving/loading, and 100% client-side processing. No accounts, no servers, no nonsense.
A privacy-first tool to split group expenses, trip costs, and dinner bills. Features an exclusion matrix and automated settlement plans. No data leaves your browser.
Add the names of everyone involved in the trip or event. These will automatically populate as columns in your matrix. Add a row for each bill. Enter a description (e.g., "Dinner"), select who paid, and enter the total amount. Click "Calculate Everything" to see a total spending summary and the most efficient plan to pay everyone back. Most bill-splitting apps require everyone in your group to download an app and create an account. The Manic Inventor Expense Matrix is designed for speed and privacy. Whether you are planning a group trip, sharing a dinner, or managing roommate expenses, you can calculate who owes whom without any technical friction.

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
