Lectio Study Helper

Highlight web pages and PDFs, see word count and reading time, and get AI summaries and explanations.

Lectio Study Helper helps you study web pages and PDFs. HIGHLIGHT Select text on any page to highlight it in yellow. Your highlights are saved and come back when you open the page again, even across links and paragraphs. Click a highlight to explain it or remove it. Turn the highlighter off from the popup when you just want to read. PDFS Open a PDF in Lectio's own viewer with one click from the popup, and highlight it like a web page. Works with online PDFs and with downloaded ones (for downloaded PDFs, turn on "Allow access to file URLs" for Lectio in chrome://extensions). WORD COUNT AND READING TIME The popup shows how many words a page or PDF has and about how long it takes to study it. AI SUMMARIES AND EXPLANATIONS (free account) • Summarize a page or PDF in 3–5 key points. • Click a highlight and choose Explain to get a short, simple explanation. Answers come in the language of the text, for example English or Romanian. Free daily limits apply. PRIVACY Highlights and settings stay in Chrome on your computer. Text is sent to the AI only when you click Summarize or Explain, and it isn't stored. No ads, no tracking.
