Get OfflineReader Explore features

Everything happens on your device

A full reading studio powered by local AI engines — no internet connection required after setup.

Natural Offline TTS

Eleven high-quality voices powered by the Piper speech engine, synthesized entirely on-device. Adjust speed, volume, and emotion modes to match your listening style.

PDF & DOCX Import

Open PDF and Word documents directly from your files. Parsing and text extraction run locally — documents are never sent anywhere.

Camera & Photo OCR

Snap a photo of a page or pick an image from your gallery. On-device OCR (tesseract.js) recognizes the text and starts reading instantly.

Karaoke Word Highlighting

Follow along word by word as the app reads. Perfect for language learners, proof-listening, and accessibility.

Trilingual Interface

Full UI in English, Chinese, and Russian — with voices and OCR support to match your reading language.

Sleep Timer & MP3/WAV Export

Drift off with a sleep timer, or export any reading session as an MP3 or WAV file to listen anywhere, on any device.

Privacy isn't a setting. It's the architecture.

OfflineReader has no servers of its own, no accounts, and no analytics SDKs. Your documents and your listening history live only on your device.

Bytes uploaded

Every document, every voice model, every synthesis happens locally. There is nothing to send.

Accounts & trackers

No sign-up, no analytics SDK, no advertising identifiers. Open the app and start reading.

100%

On-device AI

TTS, OCR, and document parsing all run on your phone's hardware — airplane mode approved.
