Information Density — The Lens

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Info Density Power-words vs. Substance ratio.

The homepage exhibits high information density with a low fluff-to-substance ratio. While headings like Sharpen your thinking and Spark ideas are somewhat abstract, the body text immediately grounds these in specifics such as personal notes, journaling, and project management. The site avoids generic performance percentages, opting instead for specific feature names like Graph, Canvas, and named community plugins including Dataview and Kanban. Substance is further demonstrated through concrete examples of use cases involving specific philosophers like Rene Descartes and David Hume within the Canvas demo text.

Information Density is read straight from the body copy: how much of the text carries grounded, checkable substance versus hollow filler. Below is the clean text the engine analyzed, then the industry’s known generic-claim patterns to weigh it against.

In Meditations on First Philosophy the philosopher René Descartes describes a series of doubts about the nature of reality, arriving at the famous phrase:

[[I thin]]

I think therefore I am
Just think about it

He argues that doubting requires thinking, and therefore, the act of thinking confirms his existence.
