Buffered keeps Save WAV available. Streaming starts sooner.
Controls payload shape for the normal TTS API URL.

Default Playback Voice

No key or setup needed — just pick it as the Active Provider above. No SLA/rate-limit guarantee since it's a shared free public queue; retries automatically on "queue full" errors.
Local ComfyUI (no API key, runs on your own GPU) is configured separately above, in the Active Image Generation Provider panel.

Active OCR Engine

Used by Magazine ingestion when a page needs OCR, or when its existing text scores poorly. Tesseract (bundled, no setup) is always the fallback if this is unreachable.

Local

Two engines were confirmed live against a real scanned magazine: Baidu Unlimited-OCR gives the most accurate text and also labels running headers/footers/page numbers/titles directly (best default). KDL Frontier Parser nano answers faster but returns plain text with no layout coordinates or labels — a usable fallback, not a first choice.
