The antidote to fluffy specs.
Facts is a developer-focused tool designed to bring clarity and precision to project documentation and specifications. It consolidates all relevant project data—such as implemented code, verified commands, ongoing specifications, and rough drafts—into a single, verifiable source. By running a 'facts check,' users can easily track the status of their project elements, ensuring everyone stays aligned and informed. Particularly suited for developers, AI teams, and project managers, Facts emphasizes transparency and accountability, reducing the noise of vague specs and unverified assumptions. Its unique approach of integrating code-backed facts with real-time verification makes it stand out as a reliable project management and documentation aid in the fast-paced world of coding and AI development.
