Dynasty fantasy football league managers who need to evaluate trades involving players and draft picks. This includes managers actively negotiating trades, those doing pre-draft or offseason roster planning, and anyone comparing their team's value against the rest of their league.

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.

DynastyTradeValues's answer:

DynastyTradeValues was built to give dynasty managers a values source that doesn't move with hype or crowd sentiment. Most existing tools rely on community voting, which can be fast to react but easy to sway by a single hyped name. This site takes the opposite approach: a fixed, transparent formula applied consistently to every player and pick.

DynastyTradeValues's answer:

DynastyTradeValues is a free public tool without named enterprise customers — it's used directly by individual dynasty fantasy football managers across leagues of all sizes.
