◆ OCR & AI‑OCR: High‑accuracy text extraction and intelligent summaries

ClarityPDF offers multi‑engine OCR (Tesseract / PaddleOCR / Local LLM Vision) and also provides a local OCR API server for automation and LAN workflows.

● OCR / Text Extraction

Extract text from PDFs and images.

Embedded text and OCR‑recognized text are separated and can be exported as JSON.

Choose from three engines:

- Tesseract

- PaddleOCR

- Local LLM Vision

Large documents can run in the background.

● PDF Summaries (AI)

Summarize entire documents or individual pages using an LLM.

Choose between:

- OCR → LLM

- Vision → LLM (direct page image analysis)

Vision‑based analysis handles complex layouts, tables, and diagrams with high accuracy.

◆ Local OCR API (Expert Mode)

Enable Expert Mode to expose your device as an OCR API server.

Other devices on the same LAN can send OCR requests directly.

- Endpoint: POST http://:/ocr

- Input: multipart/form-data (file, engine, lang)

- Output: JSON (text, confidence, per‑page results)

Ideal for automation, batch OCR, local LLM pipelines, and secure offline environments.

◆ Offline‑ready: Fast and secure

All PDF and image processing is performed locally on your device.

Only the following operations require network access:

- First‑time OCR model download

- First‑time Japanese font download

- LLM usage (only to the configured server; default is 127.0.0.1)
