Colophon

Colophon is a home library and reading tracker for book lovers: novels, essays, manga and comics. This connector lets Claude work with your own Colophon library. Ask in plain words:

• what you are reading and the page you reached;
• whether a book is already in your library (handy in a bookshop);
• to add a book by its ISBN, as owned or to your wishlist;
• to change a book's reading status or star rating;
• to log the page you reached and the minutes you read, which count toward your daily goal;
• for your reading stats for a year: books finished, pages, reading time, goals and streak;
• to append a dated comment to your review of a book or a series.

What it cannot do: delete anything, read or rewrite your written reviews, read your notes, messages or reading circles, or see other readers' libraries. Marking a book read, abandoned or back to "to read" takes two steps: Colophon first returns a summary, and nothing changes until you confirm.

You need a Colophon account, which is free: create it in the iOS or Android app or at app.colophon-app.com. You sign in on Colophon's own page and choose "Allow"; you can remove the access at any time in Colophon (Settings, Connected assistants). Colophon's answers are written in French; Claude replies in your language.

Colophon is published by Cobalio, an independent company based in France.
