Love the effort here, been thinking about what this kind of tool might look like for a while. Something like this coupled with better prosocial affordances in the medium will do a lot to improve discourse online. I wrote up one a while back [1] but things like that are only a small part of a much bigger picture.

The overall problem needs to be tackled from all angles - poster pre-post self-awareness (like respecify but shown to users before posting), reader affordances to reflect back to poster their behavior (and determine if things may be appropriate in context vs just a universal 'dont say mean words'), after-post poster tools to catch mistakes (like above), platform capabilities like respectify that define rules of play and foster a enjoyable social environment that let us play infinite games, and a broader social context that determine the values that drive all of these.
