## What is PDF AI Reader?

PDF AI Reader — Read, Listen, Learn

PDF AI Reader is an all-in-one reading, study and teaching tool for English learners and PDF readers. PDF reading, OCR tap-to-read, AI translation and explanation, multi-engine speech, annotation and interactive learning in one app. Turn one PDF into multiple languages and formats in real time.

SMART TAP-TO-READ: SEE IT, HEAR IT
Open any PDF and the app recognizes page text and marks it with red frames. Tap any text to:
• Hear the whole sentence read aloud, with smart joining across line breaks
• Translate instantly into Chinese, box above the text
• Follow along: after each sentence the app listens, scores your reading and helps you build natural pronunciation
Sentence boundaries, speech bubbles and phrases are detected, so textbooks and picture books both work. Import any English book and it becomes a talking book. Ten offline voices are free forever, with no membership or API key.

IMMERSIVE PLAYER
Tap text to open the player: read the whole sentence or word by word, drag it anywhere, read the translation aloud, loop or play in the background.

AI COMPANION READING AND AI Q&A
• AI Companion Reading: deep page-level explanation, custom prompts, presets and cached translations
• AI Q&A: multimodal chat on the page screenshot with reasoning, web search and voice questions; history saved per page
• AI Circle-to-Explain: select any area for an instant explanation
• Dictionary: tap a word for definition and phonetics

MULTI-ENGINE SPEECH
• Offline engines (Supertonic / sherpa-onnx): no network or API key, Chinese and English, adjustable voice and speed
• Qwen: multilingual voices, emotional control
• Doubao: rich character voices, including Shanghai and Beijing dialects
Adjust speed and volume, and keep listening after you leave the page.

WORD LEARNING, END TO END
• Word Memory: AI cards with SM-2 spaced repetition and four review games (spelling, listen-and-choose, missing letters, handwriting)
• Dictation Assistant: pick words from Photos, camera or a book; AI recognizes words and meanings; local-speech dictation; four activities and history replay
• Image Memory: Anki-style picture cards

MORE STUDY TOOLS
• Speaking Practice: talk about the page with live AI feedback
• Create PPT: PPTX Studio turns page content into slides with text, images, audio, video and shapes, exported as .pptx
• HTML Interactive Lessons: AI courseware you can run, play and save for reuse
• Infinite Canvas: a teaching whiteboard with unlimited pan and zoom, freehand notes and AI analysis of circled content
• Apple Pencil: handwriting is OCR-recognized and read aloud, merged with the page and saved

LIBRARY AND IMPORT
• Import from Files, camera, Photos, share sheet or drag and drop
• Folders, drag-to-organize, cover previews
• Full-screen reading, page memory, thumbnails, local storage
