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 site exhibits high information density with a low fluff-to-substance ratio. Headings like [H1] Save Anything and [H1] Create Notes are functional rather than aspirational, avoiding power words like ‘revolutionary’ or ‘next-generation.’ The body text provides specific examples of content types (cooking recipes, song lyrics) and hardware (Kindle, Kobo eReaders), though it lacks hard data points or user growth metrics. Concept repetition is minimal, restricted to the hero section and secondary feature blocks.

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.
