About

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 scenarioAt 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...

what formalism does the requirements engine use
