I've update the demo version of my math learning project. I made it more focused on learning through guided lessons and practice. I've also reduce the noise a bit. Come check it out. The demo version supports fourth grade math. No login required.

I have been working on another project. Its current big feature is that you can give an image, style and room type and it will add Ikea furniture to it and give you a list of the products. If you are interested in trying it out, DM me and I'll send you a pass.

Someone made a fun Hacker News Simulator tool where you can submit things and then it uses AI to generate comments in the spirit of HN users. I submitted my project demo.numerikos.com and the comments are great. They really feel like HN responses.

I built a math practice platform. You can practice problems by topic directly or setup a dashboard to practice different sets of problems. Currently supports 4th grade math (more coming in the future).
