Why I built this

Most digital DM tools lock core content behind paywalls or subscriptions.
I wanted a tool that was:

• Affordable (free)

• Fast at the table

• Private

• Not tied to an account or ecosystem

Over the past year I’ve expanded this from a personal initiative tracker into a full suite with hundreds of hours of development and 550+ automated tests ensuring reliability.

Browser Version
