Too hard to read means reading level C1 or harder: well above the B1 level that Dutch and EU guidance ask for in public information. Pages written for professionals, such as tax manuals, court rulings and guidance for doctors, are left out. News sits at B2 by design and is not counted.
The index measures how many pages meant for the general public are written above the reading level most people can follow, and whether an easy-read version is offered. It also checks AI Act Article 50(4): generated text that informs the public needs disclosure, unless a person reviewed it and takes editorial responsibility.
A screening model rates each page on the European reading-level scale (A2 to C2). C1 or harder counts as too hard to read for a general audience. WCAG 2.2 asks for a simpler version when text needs more than lower-secondary reading ability.
Tax manuals, court rulings, research and guidance for doctors are written for specialists and are left out of the share. Easy-read pages, explainer videos and Leichte Sprache versions count in an organization's favor.
Generated text published to inform the public on matters of public interest needs disclosure, unless a human reviewed it and takes editorial responsibility.
A public-interest page with strong AI-style writing signals, no AI label and no named author. It is a possible issue for review, not a legal finding.
Text a person reviewed and took editorial responsibility for needs no label. From outside that review is invisible, which is why a named author or an editorial statement matters.
If you chat with an AI system, you have to be told, unless it is obvious from the context. We record which chatbot a site runs; whether it says so is tested separately.
Reading level and AI-style signals come from a screening model (jev-1.13.0) run on a sample of up to 10000 public pages per organization. Formal French and German administrative text tends to rate higher than Dutch or English. A signal is a possible issue for review, not a legal finding; SC 3.1.5 is a WCAG level AAA criterion. Edition: October 2026.
WCAG 2.2 success criterion 3.1.5 Reading Level (level AAA) says that when text requires reading ability more advanced than lower secondary education, after removing proper names and titles, supplemental content or a version that does not require that reading ability must be available. Related criteria are 3.1.3 Unusual Words, for jargon, and 3.1.4 Abbreviations. WCAG and accessibility
Public sector websites in the EU must meet the Web Accessibility Directive (EU) 2016/2102 through the standard EN 301 549, which refers to WCAG level AA. Reading level (3.1.5) is a level AAA criterion, so it is not mandatory under that standard. Many governments do have plain-language policies; Dutch government guidance, for example, aims for language level B1 in public information.
The Common European Framework of Reference (CEFR) runs from A1 to C2. At B1 a reader understands the main points of clear, standard text about familiar matters; most adults can follow it. C1 means long, demanding texts with abstract language, which a large group of readers, including people with low literacy, cannot follow. In this index a page meant for the general public counts as too hard to read at C1 or harder.
The European Accessibility Act, Directive (EU) 2019/882, applies since 28 June 2025 to products and services such as e-commerce, banking, transport and e-books. It requires information about these services to be perceivable, operable, understandable and robust. Organisations usually meet the "understandable" requirement with WCAG and plain-language guidance.
For this index a decision model rates the main text of each sampled page on the CEFR scale, from A2 to C2. The measure was checked against pages labelled by hand and against classic readability formulas such as Flesch, Flesch-Douma and LIX. Pages written for professionals, such as tax manuals, court rulings and guidance for doctors, are left out, and easy-read versions count in an organisation's favour.
Write short sentences, address the reader directly, use active verbs, explain jargon and abbreviations the first time, put instructions in steps, and offer an easy-read summary or explainer video for complex topics. Typetone checks every page for reading level, jargon and unexplained abbreviations, rewrites flagged passages to B1, and routes the changes through your editors before publication. Talk to Typetone
From 2 August 2026, organisations that use AI to generate or manipulate text published to inform the public on matters of public interest must disclose that the text was artificially generated or manipulated. The duty does not apply when the text has gone through human review or editorial control and a person or organisation holds editorial responsibility. Breaches of Article 50 can be fined up to €15 million or 3% of worldwide annual turnover.
Yes. Article 50(1) of the AI Act requires AI systems that interact with people to be designed so that people are told they are dealing with an AI system, unless that is obvious from the context. The rule applies from 2 August 2026.
Typetone scans public websites against WCAG, plain-language and AI Act rule sets, shows which pages are too hard to read or lack disclosure, explains each issue and suggests a compliant rewrite, so editors can fix pages in bulk with a full approval trail. Request a scan
