DiagramTheGame connects the entire coaching-content workflow.

DiagramTheGame's answer
DiagramTheGame began in 2016 as LacrosseLabs (lacrosselabs.io), a focused play-design tool for lacrosse coaches. The product gradually expanded from diagramming into playbooks, practice plans, scouting reports, team collaboration, and player access. As support expanded beyond lacrosse into basketball, hockey, floorball, field hockey, ultimate, volleyball, handball, and water polo, the product became DiagramTheGame to reflect the broader multi-sport platform.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
