Ten clear checks

Reading level, sentence and paragraph length, headings, link text, abbreviations, capitals, emojis, hashtags and fancy Unicode letters.

Know why it matters

Every check names the guideline it comes from and explains who it helps, so you can fix what matters most first.

Fixes that keep your words

Split long paragraphs, turn fancy letters back into normal ones, add headings. Only the shape changes, with one-click undo.

Before and after

Same words, new shape. Nothing is rewritten, only split and bolded.

How to write text everyone can read

  1. Aim for a reading level most adults can follow easily: short sentences, everyday words, one idea per sentence.
  2. Keep paragraphs short and add a heading every few hundred words so people can find their place.
  3. Make links say where they go (“read the pricing guide”), never just “click here”.
  4. Spell out abbreviations the first time, avoid ALL CAPS and fancy Unicode letters, and put emojis at the end of a sentence.

One draft, every platform

Questions

What does the accessibility checker look at?

Reading level, sentence length, paragraph length, headings, “fancy” Unicode letters, link text such as “click here”, unexplained abbreviations, ALL CAPS, emojis in the middle of sentences and lowercase hashtags.

Will this make my content WCAG compliant?

No tool can promise that on its own. Readology checks your text against WCAG 2.2 and plain-language guidelines. Images, colours and the website you publish on also affect accessibility.

Why avoid “bold” Unicode text on social media?

LinkedIn and X have no bold button, so bold text is made from special math letters. Screen readers often spell them out letter by letter or skip them, so blind readers miss the words.

Is it free?

Yes, everything is free. Your words are never rewritten.
