AI Text Simplifier

Translate complex jargon, legalese, and dense academic text into plain, clear 8th-grade English.

Runs on your device by default. The optional cloud AI mode sends your input to Google Gemini.

What the AI Text Simplifier does

Legal clauses, policies and technical documents are often written in long sentences full of words like "notwithstanding" and "subsequent to". This simplifier turns them into plain English and measures the difference with the Flesch reading-ease score and school grade level. The on-device engine replaces more than 150 wordy phrases and formal words with plain ones and splits sentences joined by semicolons, all in your browser. The optional Cloud AI mode sends the text to Google Gemini for a full plain-English rewrite. Both show before-and-after scores and flag sentences that are still too long.

How to simplify complex text

  1. Choose On-device for private word and phrase replacement, or Cloud AI for a full rewrite.
  2. Paste the text. The current reading-ease score appears under the box as you type.
  3. Press Simplify, or Ctrl + Enter.
  4. Compare the reading ease and grade before and after, and open Show changes to review each edit.
  5. Split any sentences listed under "Still long", then copy the result.

The AI Text Simplifier runs on your device by default. If you switch to the optional cloud AI mode, your input is sent to Google's Gemini model to produce the result.

When to use it

Understanding a contract or policy

"Notwithstanding the aforementioned stipulations, the contractor shall endeavour to expeditiously facilitate…" becomes "Despite the above conditions, the contractor must try to quickly help…" — the obligation is suddenly clear.

Writing for customers

Help articles, notices and instructions work best at a reading ease of 60 or above. Measuring a draft and replacing jargon gets it there without dumbing down the content.

Accessible public information

Government and health guidance is read by people with a wide range of reading skills and by many who read English as a second language. Plain words and short sentences help all of them.

Good to know

  • A reading ease of 60–70 is plain English; 30–50 is typical of academic writing; below 30 is very hard going.
  • Sentences under about 20 words are easiest to follow. The tool lists anything over 25 words so you can split it.
  • Keep technical terms your readers must know, but explain them the first time they appear.
  • For legal text, use the simplified version to understand the meaning, and rely on the original wording for anything binding.

Frequently asked questions

What reading level does this aim for?

Plain English, which is a Flesch reading ease of 60 or more — roughly what a 13- to 15-year-old reads comfortably. The tool shows the score before and after so you can see how close you are.

How is the reading-ease score calculated?

Flesch reading ease = 206.835 − 1.015 × (words ÷ sentences) − 84.6 × (syllables ÷ words). Long sentences and long words both lower the score. The grade level uses the related Flesch–Kincaid formula and approximates a US school grade.

Why did my score barely change?

The on-device engine replaces words and phrases but cannot restructure long sentences, which have the biggest effect on the score. Split the sentences listed as still long, or use Cloud AI for a fuller rewrite.

Does simplifying change the meaning?

It should not: the on-device replacements are chosen to mean the same thing in context, and Cloud AI is instructed to keep every fact and obligation. Still compare the two versions when accuracy matters.
