Calculators didn't replace mathematicians, they replaced doing arithmetic by hand. Most of the other tools are paid or with ads this is free and no ads

Most of the other "tools" posted to HN within the past year are near identical to yours because you've not bothered to consider what you're building and why. You've asked an LLM for a weekend project idea and gone with one of the most recurrent suggestions. From that, you've let the LLM generate the same basic web app as every other person who has been equally lazy in approach.

I'm sorry to be harsh but submissions like this are the reason HN is a less interesting showcase for personal projects nowadays.
