From a document to a comfortable reading session
ReadFlow makes it easy to move between reading and listening without losing your place.
Add a document
Upload a PDF, Word, text, or Markdown file, or paste text. Signed-in users can import a public web URL. Scanned PDF pages use browser-based OCR; choose English, Hindi, or both before upload.
Open the reader
Use the contents list or document search to find a passage. Click a paragraph to start there. On a PDF, the original page remains visible.
Listen and follow along
Press Play and choose a device voice, speed, and volume. ReadFlow highlights words when the browser reports word boundaries. If a voice does not report them, follow at the sentence level.
Save your ideas and place
Select a sentence to bookmark it, highlight it, or attach a note. Tags organize your library. Your reading position is saved as you go.
Choose where to keep it
Without an account, your documents stay in this browser. With an account, ReadFlow syncs them privately. You can select individual synced documents to keep available offline on the current device.
