EchoLeaf

EchoLeaf turns reading into listening. Open a PDF, TXT, Markdown, HTML, or RTF document, paste text from your clipboard, or write a quick note and let your device read it aloud. The app is designed for focused listening with local text-to-speech that works offline. Choose from multiple voices and listen in more than 30 languages. Scan a page with OCR when the words are only on paper, then review the extracted text before listening. Text highlighting helps you follow along while the document is read, and you can return to your library to continue where you left off. Use EchoLeaf for articles, study notes, saved documents, recipes, and any text you want to hear while your eyes are busy. Keep playback going in the background and make listening part of your everyday routine, at home or away from a connection. Your reading library stays close at hand, with documents, notes, and pasted passages organized for the next session. EchoLeaf keeps the experience simple: bring in text, choose a voice, press play, and follow along at your own pace.
