LumenRead

LumenRead is a free reading speed test that measures words per minute (WPM) alongside comprehension. Users can paste text, upload a TXT or Markdown file, or choose a sample article, then read at a guided pace using word-by-word or sentence-by-sentence display modes. After reading, an AI service generates three multiple-choice questions covering factual understanding, inference, and the main idea to produce a comprehension score. No account is required to use the tool.
