Audience before simplicity
A specialist document can remain technical. The question is whether its language, structure and assumptions fit the people who need it.
Clarity is more than a readability formula.
PlainSight combines audience-aware readability analysis with deterministic measures and plain-language rules. It scores content, protects meaning and identifies ways to simplify complex writing. AI may propose wording, but it does not set the framework or decide what passes.
Measures without false precision
Stable calculations support the assessment, while human-like judgement is used only where context matters.
Meaning before score
Protected wording and a separate meaning check take priority over achieving a higher score.
The Clarity Score
Five visible dimensions, one useful view
The readability score is part of a broader plain-language assessment out of 100. It is designed to help teams find and prioritise barriers, not certify content or claim scientific certainty.
- Audience fitDoes the content match the reader's knowledge, context and needs?27%
- UnderstandingAre sentences, terminology and relationships easy to follow?25%
- ActionabilityCan readers identify what they need to do, when and how?20%
- StructureCan readers find key information and understand its sequence?18%
- Reading easeHow demanding are the sentence and word patterns?10%
Supporting measure
Flesch Reading Ease
PlainSight calculates Flesch Reading Ease directly. It uses the average number of words per sentence and syllables per word:
206.835 − 1.015 × (words ÷ sentences) − 84.6 × (syllables ÷ words)A higher score generally means the text is easier to decode and requires less reading effort. Flesch cannot tell whether information is accurate, well ordered, actionable or appropriate for a particular audience, so it contributes only 10% of the Clarity Score.
