About

Opuss is a commonplace book.

For centuries, readers filled a single notebook with the passages worth returning to: a commonplace book. A sentence from a novel, a line of a poem, a thought from a letter. Not a diary and not a scrapbook, but a private anthology of borrowed words, collected slowly, returned to often. Opuss is that practice, rebuilt for the way we read now.

What it does

You collect a passage from anything you are reading, on your phone, from the share sheet, in a few seconds. Opuss holds it, plainly and beautifully. You can add a private annotation, a note to your future self about why it mattered. And later, once you have half-forgotten it, the passage returns to you as a recollection: a quiet resurfacing of something you chose to collect.

If a passage deserves an audience, you can publish a single item as its own page. Everything else stays private.

Page over platform

Opuss has no feed, no algorithm deciding what you see, and no metrics turning reading into a performance. There are no likes, no followers, no streaks. A collected item is the unit, and the page is the page. The design tries to disappear so the words can be the only thing in the room.

What you keep is yours

An item you collect is a quotation from someone else's work. You are its keeper, not its author. Your annotations are your own words, and they stay private unless you choose to publish them. We never attach your name to a passage when it helps the service work for another reader.

A little history

Opuss first launched in 2013. It was featured by Apple, found an audience, and then ran out of money, the way small things often do. It lingered, then quietly went away.

A decade later it is back, rebuilt from scratch as a solo project by its original founder. No venture money, no team of thirty. Just an idea that deserved another attempt, made with everything learned in the years between, and pointed at something simpler this time: the small, durable habit of collecting what you read.
