Colophon
Your story bible and your drafts, on your Mac, in files you own.
The bible
Characters, locations, threads and timeline, linked to the scenes they appear in.
The manuscript desk
Points at the folder your drafts already live in — Scrivener, Ulysses, iA Writer, Obsidian or plain Markdown — and keeps a permanent, paragraph-level record of what changed between one reading and the next. Search finds a line even after you cut it.
Continuity
An issue tracker for fiction. A novel makes hundreds of small factual promises; this is where you keep the ones it still has to pay.
Your files stay yours
Colophon opens your manuscript folder read-only and never connects to the internet. Privacy Policy.
