How to make text more readable
- Shorten sentences. Aim for 15-20 words on average. If a sentence has more than one comma, consider splitting it.
- Simpler words. “Use” beats “utilize”. “Help” beats “facilitate”. Cut Latin, keep Anglo-Saxon.
- Active voice. “Hyperleap built the chatbot” beats “The chatbot was built by Hyperleap”.
- One idea per paragraph. Web readers scan — short paragraphs are visually easier.
- Lists for parallel items. Three or more parallel things become a bullet list.
For LLM-friendly readability (how ChatGPT and Perplexity chunk your content), use LLM Readability Score.
