A calm, guided screen from setup to report

Every task is short and clearly explained. Content changes with age, while the overall flow stays familiar.

01

Quick tech check

Check the camera, microphone and room noise before the timed tasks begin.

02

Writing sample

Photograph a recent, uncorrected piece of writing with at least five sentences. We describe visible patterns; we do not diagnose from handwriting.

03

Words and made-up words

After one practice item, classify 20 age-appropriate letter strings as real or invented.

04

Speech sounds

Short picture tasks cover rhyme, syllables, first and last sounds, deletion, substitution and segmentation.

05

Visual speed and sequencing

A no-audio, RAN-inspired task measures fast visual search, sequencing, confusable symbols and short-term order memory.

06

Read aloud for one minute

Read an age-appropriate text. The system looks at pace, word accuracy, pauses, repetitions and self-corrections.

07

Sentence understanding

After one practice item, answer 10 short, age-appropriate true-or-false sentences.

BORN FROM A REAL FAMILY CHALLENGE

Three screenings. Still no clear answer.

Nora's son Lukas was visibly struggling with reading. Yet his dyslexia remained unrecognized across three well-intentioned screenings. The family received isolated scores and general feedback — but no clear picture of where the difficulties lay or what would actually help next.

This is precisely why Dyslexia99 was built: a screening that goes beyond a single total score to make individual reading component skills visible.

Our goal is to help families understand earlier which patterns stand out, where strengths lie, and when further support makes sense.

From uncertainty to a useful first picture

Families do not need another generic checklist. They need to see what happened in the actual tasks and what the pattern may mean.

Before

  • You notice slow, effortful reading but are unsure how serious it is
  • Free quizzes ask broad symptom questions without testing skills
  • School feedback can arrive late or focus on one overall score
  • A full assessment may be costly or take months to arrange
  • You leave with concern but no clear next step
Dyslexia99

With Dyslexia99

  • A guided, age-adjusted screen completed at home
  • Direct tasks across words, sounds, visual speed, reading and sentences
  • Observable handwriting and read-aloud patterns shown separately
  • A detailed PDF with strengths, warning signs and uncertainty
  • Clear guidance on when to monitor, support or seek professional assessment

Built for the questions parents actually have

The product stays simple on the surface while collecting the detail needed for a responsible interpretation.

Fast enough to finish

The core screen is designed to stay close to 10 minutes, with one practice item before each task type.

More than a symptom quiz

The child or adult performs real reading-related tasks instead of only answering whether certain problems sound familiar.

A profile, not a label

See performance by module, task quality and uncertainty. No single number is presented as a diagnosis.

Age-adjusted content

Routes for ages 7–9, 10–12, 13–17 and adults use the same structure with different words, texts and difficulty.

Useful after the result

The report explains sensible next steps and prepares a learner profile for the upcoming adaptive reading app.

Privacy without ad tech

The website uses no advertising trackers. App consent, research permission and marketing permission are kept separate.

Methodology

What the screen measures

Dyslexia is not captured by one trick question. Dyslexia99 combines complementary tasks so that speed, accuracy and error patterns can be considered together.

  • Writing sample: visible spelling and handwriting patterns such as word and sentence counts, spelling errors, phonetic plausibility, reversals, spacing, letter size, baseline, formations, corrections and omissions/additions.
  • Word recognition: one practice item followed by 20 scored real-word and pseudoword decisions, selected from a planned pool of 100 items for each age route and language set.
  • Phonological awareness: three scored items in each of seven areas — rhyme, syllables, first sound, last sound, phoneme deletion, sound substitution and segmentation — selected from a planned pool of 140 items per age route and language set.
  • Visual speed and sequencing: a no-audio proxy task that captures search speed, order, confusable symbols and a small working-memory component.
  • One-minute read-aloud: an age-appropriate text selected from a planned set of 20 per age route and language, with pace, decoding accuracy, errors, substitutions, pauses, repetitions and self-corrections analysed.
  • Sentence understanding: one practice item and 10 scored statements selected from a planned pool of 100, with accuracy and response time tracked.

Your report

Every result remains visible and explainable

The first release uses transparent task rules plus model-assisted interpretation. Until a validated statistical model is available, the report avoids claiming an exact clinical probability.

  • Overall interpretation with a clear screening disclaimer and uncertainty level.
  • Module-by-module values, response quality and the most relevant observed patterns.
  • A downloadable PDF that can support a conversation with a school, tutor or qualified professional.
  • A unique learner ID that can later connect the profile to the adaptive reading app without exposing the child's name in the code.

Privacy & security

Sensitive learner data deserves a narrow purpose

The public website has no database, no forms and no advertising cookies. The screening app will collect only what is needed for the screen and the choices a parent actively makes.

  • Screening consent, optional research use and marketing email permission are separate.
  • A prior dyslexia status is required for context but is not used to inflate the task score.
  • Identity data, assessment events and audio or image files should be stored separately with strict retention rules.
  • No learner data is sold or used for unrelated advertising.
Accessibility

Low-stress, readable and mobile-first

A screening is only useful when the person can understand what to do and comfortably complete it.

  • Large tap targets, strong contrast, plain language and generous spacing.
  • Dyslexia-friendly reading presentation with larger type and line spacing during read-aloud.
  • Audio and camera checks happen before timed tasks.
  • Reduced-motion preferences are respected throughout the website.

Implementation

Designed for a real home, not a perfect lab

The screen gives clear setup instructions and marks results as uncertain when the conditions are not good enough.

  • A quiet room, a recent writing sample, camera access and a working microphone are required.
  • The timed core remains close to 10 minutes; setup and consent happen before it.
  • Audio quality, interruptions, repeated instructions and device details are tracked as quality signals.
  • The same task structure is used across ages; only the content and difficulty change.

Bias & fairness

Language versions are built, not simply translated

Reading patterns differ by language, age and learning history. A single global score would hide those differences.

  • Initial content sets: German, US English, UK English and Spanish for Spain.
  • Canadian and Australian English do not need separate website languages at launch; separate norms are added only when data supports them.
  • Every item stores its language, age route, version and difficulty so performance can be audited.
  • Results should be checked across age, language, sex, multilingual background and device before strong claims are made.

Research ethics

A screening estimate must stay a screening estimate

Dyslexia99 is built to support an earlier, better-informed next step — not to replace qualified diagnosis or create false certainty.

  • No medical, psychological or educational diagnosis is provided.
  • Handwriting features are described as observable patterns, not proof of dyslexia.
  • The visual-speed module is described as RAN-inspired, not as a classic spoken RAN test.
  • Model versions, task versions and quality flags are saved so results remain auditable.

Six areas. A research-backed holistic view.

Dyslexia99 combines established approaches from word recognition, phonological processing, reading fluency, sentence comprehension, and supplementary handwriting analysis into one guided screen. The specific combination and evaluation are continuously refined with real usage data.

Single-word recognition

Lexical decisions with real words and pseudowords are used in Stanford's validated ROAR-Word assessment.

Stanford ROAR-Word

Phonological awareness

Sound matching and phoneme deletion are established early-reading measures and core parts of ROAR-Phoneme.

Stanford ROAR-Phoneme

Naming speed and fluency

Large reviews and meta-analyses find a meaningful relationship between rapid naming and reading performance.

Araújo et al., 2015

Sentence reading efficiency

Fast, accurate sentence understanding adds information beyond single-word reading alone.

Stanford ROAR-Sentence

Handwriting as supporting context

Writing can reveal useful observable patterns, but handwriting alone is not specific enough to diagnose dyslexia.

Why families no longer want to just wait and see

Parents consistently describe the same three situations.

“I can see my child struggling — but nobody can tell me how serious it is.”

Parents often describe children falling further behind while they wait for a school referral or clearer feedback.

“Months pass before a full evaluation is possible.”

Cost, insurance coverage, location and long waiting lists can delay a comprehensive professional evaluation.

“I need more than a generic online questionnaire.”

Families want to understand the pattern behind slow or inaccurate reading and what a sensible next step looks like.
