AI Disclaimer

AI was used during the development of this project. I used about 80% Cursor and 20% Antigravity with Gemini 3.

I used AI because I have very limited time and have issues completing projects. I was interested if AI can help me with that. I also wanted to evaluate different AI services, so it was also a way to compare/benchmark them.

Since I usually can't dedicate that much time to a project, it is not uncommon that a project dies before getting to a point where it is usable. Here, with the help of AI, I was able to reach and sustain much higher pace of development. The ability to skip boring bits, or stuff I didn't feel like doing at the time helped me to keep focus and interest.

I was able to bring this project into completion (from idea to production, complete in the sense of the scope I set out to do originally) in about 20 hours.

I call this a win.

Developer Guide

Prerequisites

3. Prepare your Postgresql instance
4. Either with docker - docker compose up -d
5. Or yourself - hostname localhost - database spend_track_dev - user postgres - password postgres - or customize this in config/dev.exs
