I made my own coding assistant (a clone of cursor) in a week.

AI that talks to your infra. An AI "on call" agent

Bunch of AI agents play a game of mafia and try to lie to each other. Asynchronous AI communication

Deep research agent (perplexity clone). Multi agent search retrieval system

Perplexity for Github. Easier way to navigate and understand codebases

AI product recommendation: AI that watches MKBHD's YT video to tell you which iPhone to buy
