Transform hand-drawn doodles into animated memes.
hjessmith · HN
I like doodling, and I like character animation. I made a little tool that can animate your hand drawn characters and put them into an animated meme. It's free, there's no login needed, and it uses an animation pipeline (not generative AI) to create the outputs. Works on desktop and mobile. If you give it a try, I'd love to hear your feedback. Thanks!

AI tool that asks clarifying questions and generates verified specifications for coding agents.
jayaprabhakar · HN
I've been building an open source formal methods system (fizzbee.io) for the past few years. Today I'm launching a new app built on the same technology. It performs requirements engineering using formal verification to uncover gaps and produce precise instructions for your coding agents to follow. When given a prompt, it - asks high signal follow-up questions - converts to formal spec and identifies complex requirements gaps - generates validation scenario At the end, it produces a specification document that can be shared with coding agents. In my trials on various projects, it produces working code in fewer iterations. Please give it a try and share your feedback. https://fizzbee.ai/ You can also look at a sample project. https://fizzbee.ai/projects/94bf2869-97a1-445c-8f5d-4445848b...
