Ray▲293I've been using this daily for 4 months and figured others might find it useful. This is my first open source project so would love any feedback. Ray connects to your bank via Plaid, stores everything in an encrypted local SQLite database, and lets you ask questions about your finances in natural language. No cloud, no account, your data is stored on your machine. Before anything reaches the LLM, all PII is stripped — your name, companies, transaction details are redacted and replaced with tokens, then rehydrated locally in the response. The AI never sees who you are.

The map currently includes hundreds of startups from Sao Paulo and their job opportunities. The most interesting thing I've learned so far is how clustered startup activity is in a handful of areas. I'd love to hear your thoughts. The EN version: https://www.startupsbr.com/sao-paulo

Hi HN, I wanted to share an app I've created recently since it might be useful for you: guitos is a free open-source budgeting app that helps you figure out where your money went and plan your budget ahead of time. It was initially created to replace a spreadsheet I created based on the budgeting advice given on the r/personalfinance subreddits and as an opportunity to learn React. The app stores data in your browser's local storage (IndexedDB). Your private financial data doesn't leave your browser.
