No description
Add PDF_PARSER_VERSION constant and propagate parser versioning throughout the PDF parsing, job, and API layers. Implement normalization of parse state to ensure compatibility with the current parser version, and enable reuse of parsed PDF results when possible. Add isPlaybackReady state to document hooks and TTS player, improving playback UX by disabling controls until content is ready. Update tests to reflect new playback readiness logic. BREAKING CHANGE: PDF parse state and job logic now require explicit parserVersion; older parse states may be treated as pending until reprocessed. |

📄🔊 OpenReader
OpenReader is an open source, self-host-friendly text-to-speech document reader built with Next.js for EPUB, PDF, TXT, MD, and DOCX with synchronized read-along playback.
Previously named OpenReader-WebUI.
Get started in the docs.
✨ Highlights
- 🧱 Layout-aware PDF parsing with PP-DocLayoutV3 (ONNX) — structured block detection, cross-page stitching, and geometry-based highlighting for precise read-along sync.
- ⏱️ Word-by-word highlighting via ONNX Whisper alignment through the compute worker control plane (NATS JetStream-backed).
- ⚡ Segment-based read-along for EPUB, PDF, TXT, MD, and DOCX — sentence-aware TTS with cached audio segments, background preloading, and resumable playback.
- 🎯 Multi-provider TTS — self-hosted OpenAI-compatible servers (Kokoro-FastAPI, KittenTTS-FastAPI, Orpheus-FastAPI) or cloud APIs (OpenAI, Replicate, DeepInfra).
- 🎧 Audiobook export in
m4b/mp3with resumable chapter processing. - 🗂️ Flexible backend — embedded SeaweedFS or S3-compatible storage, SQLite or Postgres, server library import, and device sync.
- 🐳 Self-host friendly — Docker (amd64/arm64), built-in auth/session support, and automatic startup migrations.
