Users can upload a PDF or open a sample paper, then listen as the service narrates the document and highlights the spoken words. It is intended for research papers, reports, articles, manuals, books, and other PDFs with text. The reader prepares each page for listening by interpreting its layout, text, mathematics, and figures. It can preserve the reading order of two-column papers, skip common page furniture such as running headers and reference lists, and keep the original page available beside the reading view. Documents can be revisited from a personal library, with reading position and settings saved to the account. ## Read PDF Out Loudでできること ### Natural-voice narration Listen to a document from start to finish using one of four available narrators: Theo or Elaine in American English, Quentin in British English, or Tamsin in New Zealand English. ### Word-level highlighting The current sentence is shaded and each word lights up as it is spoken. Users can click any word to begin reading from that point, or use the player to move through the document. ### PDF layout and math handling Two-column layouts, headings, captions, equations, tables, code, footnotes, and other document elements are interpreted for reading. Equations are spoken by meaning rather than as an unstructured sequence of symbols. ### Figure, table, and equation summaries An optional Summaries setting provides short spoken explanations of figures, charts, tables, code listings, algorithms, and displayed equations. These AI-generated summaries are presented as a guide and should be checked against the page. ### Synchronized document views Text, Original, and Side by side views let readers choose between a simplified reading view, the printed PDF page, or both. In Side by side mode, the relevant part of the original page is framed as it is discussed. ### Adjustable listening and reading controls Playback speed ranges from 0.75× to 2×. Settings include four fonts, adjustable text size, light, sepia, dark, or device-matched themes, optional text-box narration, automatic page turning, and automatic playback on new pages. The document text can also be downloaded as a plain-text file. ## 利用シーン ### Research papers and academic reading Listen to papers with two-column layouts, equations, citations, figures, and tables while following the original page when visual context is needed. ### Students and researchers on the move Use a browser on a computer, tablet, or phone to continue listening to lecture notes, textbooks, and papers, with saved progress available when returning to a document. ### Accessibility-focused reading Follow the spoken text through word highlighting, larger text, a calm theme, and the Atkinson Hyperlegible font. The tool is presented for readers with dyslexia, ADHD, or low vision, although individual suitability may vary. ### Reports and professional documents Listen to reports, contracts, manuals, white papers, and similar documents while away from the screen or doing another task. ### Reducing screen fatigue Use narration to give your eyes a break after extended screen reading while retaining access to the page and text views. ## よくある質問 ### How do I start reading a PDF?

A free account can add up to 500 pages per month, with the monthly count resetting on the first day of each month.

It can also provide optional summaries for figures, tables, code, algorithms, and displayed equations. ### Can I use it on a phone or tablet? Yes. The site works in a browser on a computer, tablet, or phone.
