The NoteRank algorithm

Google's PageRank algorithm helps us navigate billions of web pages and find just the one we need right when we need it. ixnote's NoteRank algorithm does the same for your growing graph of notes. NoteRank helps you find the note you need among thousands; without elaborate folder architectures.

The half-life of a note

Some of the notes you take today will be keepers; as you type them, you know they capture something timeless, an idea, or an important fact. Others are more transient, like the meeting notes from today's standup. Who attended, new to-do's, etc., will have little or no value three weeks from now.

Unfortunately, most note systems can't differentiate between the two, so the hard work of managing a growing collection of notes falls to you. Is that what you signed up for?

In ixnote, notes have a half-life; they drop in value with neglect. So the standup note you took yesterday, and checked again today, perhaps for the last time, will fade into the background over time. Leaving the gems, the notes you regularly revisit, at your fingertips.

No need for overly complex note-sorting workflows with inboxes, folders, and daily/weekly maintenance tasks you know you will forget to do.

The NoteRank algorithm

Like Google PageRank, the ixnote NoteRank algorithm is simple on the surface.

Every note node has the same NoteRank value when created; each day, the NoteRank value is reduced by a fraction, simulating half-life decay. When you tap or link a note, its NoteRank gets a boost, and all linked nodes also get a fractional boost.

This system's daily degrading of NoteRank, combined with NoteRank boosting upon access, mimics our brains' memory management system. The difference is, in ixnote, infrequently accessed memories aren't lost, just hidden.
