bLoam is a note-taking app. Notes are plain Markdown files in a folder you own; the app is what makes them talk to each other.dBacklinks. Every note you write about a source appears on the source. Every source appears on the note.fThis layout is a thousand years old: the text in the middle, the commentary around it. It is still the best picture of how thinking accumulates.

Apparatus

What the app does, entry by entry.

capture ]
Clip a passage from the web, a PDF, an email, or a photo of a page. Loam keeps the source and the exact location.
margin ]
Write beside the passage, not beneath it. Your note and its source stay on one page.
backlinks ]
Every reference runs both ways. Delete nothing; the page remembers.
resurfacing ]
While you write, related notes from years ago appear in the margin. You reread what you would have lost.
search ]
By word or by meaning, across every page, offline.
files ]
Each note is a Markdown file in a folder you own. Loam reads them; it doesn't hold them.
sync ]
End-to-end encrypted between your devices. Optional.

What you read on the left. What you thought on the right. Loam keeps them facing.

Source · Seneca, On the Shortness of Life, §1

It is not that we have a short time to live, but that we waste a lot of it. Life is long enough, and a sufficiently generous amount has been given to us for the highest achievements if it were all well invested. But when it is wasted in heedless luxury and spent on no good activity, we are forced at last by death's final constraint to realise that it has passed away before we knew it was passing.

“Well invested” is a scope problem

Seneca isn't saying work harder. He's saying decide what the time is forbefore it's spent. Same claim as Parkinson's law from the other direction: the deadline is the scope.
