About Sepia
A small pack for taking the AI flavor out of writing. Sepia has modes to write from scratch, review a draft and point out AI tells without editing, make small in-place fixes, or do a full rewrite. A Hemingway-style mode is included too.
Professional text gets rules that fit the format: release notes, PR replies, code review comments, postmortems, tickets, blog posts. For fiction it works on story structure, based on the StoryScope research paper. Ships as plain skills plus native plugins for several coding agents.
