the problem

The problem it solves#

Community chat tools often trade convenience for control over data, branding, and moderation rules. Teams looking for a Discord-style alternative usually want private communication, customization, and a way to avoid vendor lock-in.

The current public repository linked for Adapt is a branding repository, not the full application source. That means editorial copy should stay conservative until the main implementation repository is verified.
