Interactive platform for learning data structures and algorithms with 300+ problems and visualizations.

The reason was simple: I could code, but I never properly understood Data Structures and Algorithms. I spent almost a year learning DSA after that. During that time, I realized I don't learn by memorizing. I learn by building. And I couldn't find a tool that taught DSA the way I wanted to learn it. So I

Log dreams and discover recurring patterns with color-coded charts.
u/sucsforyou · Reddit
I built Dreamotif, a private dream journal that calculates what keeps coming back. No AI. Dreamotif is a private journal that calculates the motfis - the recurring themes and elements in your dreams - the motifs.

Investigate current grifts and scams using a RAG-powered research tool.
u/King_Kazma · Reddit
whatsthegrift.com - a RAG research tool for today's grifters every day i feel like there's a new grift attached with some news article, which naturally birthed the idea to built something to investigate & visualize them examples: https://whatsthegrift.com/q/777063a64e512565 https://whatsthegrift.com/q/e5945d20375ed3ff and my personal favorite so far: https://whatsthegrift.com/q/f43eb30a15342d53 react (vite) + node (fastify) + brave search (retrieval) + claude haiku (extraction)

We also have ADR, AGENTS.md, LLMs, and a few other free tools.
