An Obsidian plugin that surfaces the notes you actually use. Notes you actively visit glow brighter in a ranked sidebar; ones you haven't touched fade out. No tags, no manual curation — just open notes and let the glow tell you where your attention lives.
Most note-taking setups bury active work under search results and folder hierarchies. Cognitive Glow gives you a persistent, at-a-glance view of what matters right now, ranked by a blend of recency and visit frequency.
- Visual glow — each note gets a luminous bar proportional to its score. High-activity notes shine; old ones dim.
- Normal and Focus modes — Normal shows your full ranked list; Focus narrows it to your top N.
- Dwell-time gating — visits only count after a configurable minimum open time (default 30 s), so quick flick-throughs don't inflate scores.
- Folder scope — restrict tracking to specific folders, or exclude folders like
Templates/orArchive/. - Sidebar placement — left or right, whichever fits your layout.
- Ribbon shortcut — sparkles icon in the ribbon opens the panel.

recency = exp(-(now - lastOpened) / tauRecencyMs)
frequency = log(1 + hitCount) / log(1 + hitCountMaxScale)
gravity = manualGravity (0 if unset)
glowScore = wRecency * recency + wFrequency * frequency + wGravity * gravity
Weights are normalized if their sum exceeds 1. See SPEC.md for full implementation details.
