About
Read Faster Without Losing Comprehension
LumenRead is a free online reading-speed and comprehension tool designed to help you understand not only how fast you read, but also how much you retain.
Instead of testing you with a fixed passage, LumenRead lets you practice with content that matters to you. Paste your own text, upload a .txt or .md file, or choose from the included sample articles. Set a target pace, select word or sentence mode, and begin a focused reading session directly in your browser.
While you read, LumenRead measures active reading time and automatically pauses when the browser tab is no longer visible. English content is measured in words per minute (WPM), while Chinese content uses readable characters per minute (CPM).
After the session, you can answer three AI-generated comprehension questions based on the article. These questions cover factual understanding, inference, and the main idea, helping you see whether your reading pace supports genuine comprehension rather than simple skimming.
Your final report brings the most useful signals together:
Actual reading speed in WPM or CPM
Active reading time
Article completion
Comprehension results
Short, practical advice for your next session
LumenRead requires no account or sign-up. Uploaded files are read inside your browser, and the original files are not saved to an application database or object storage. This makes it easy to run a quick test without creating a profile or building a permanent reading history.
The goal is not to chase the highest possible number. Reading speed changes with the difficulty of the material, your familiarity with the subject, and your purpose for reading. LumenRead helps you establish a personal baseline and gradually find a pace that improves efficiency while preserving understanding.
Whether you are reading for study, work, language learning, or personal development, LumenRead offers a simple way to turn everyday articles into focused reading practice.
Try LumenRead with your own text and discover the pace at which you read best.
