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.

Information density is exceptionally high with a fluff saturation of 0 percent. Headings like [H2] License and [H2] The main features of 7-Zip lead directly into dense technical data and legal terms. The body text provides specific metrics such as ‘AES-256 encryption,’ ’87 languages,’ and exact file sizes like ‘1.6 MB’ for version 26.01. There is no evidence of concept repetition; every paragraph introduces new technical requirements or functional capabilities.

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.
