iPad
Read PDFs and EPUBs, collect excerpts, and write by hand on iPad. Connect your home library and keep reading, notes, and review together.
InkCoach brings reading, handwriting, and English study together on iPad. Keep source material, excerpts, and your own thoughts connected, and return to the original whenever you need context.
READ AND COLLECT
• Import PDFs and EPUBs, or connect a compatible OPDS home library to download books.
• Select PDF text, save excerpts, and keep a link to the source in your notes.
• Navigate with contents, bookmarks, and page overview; adjust EPUB font size and reading themes.
WRITE AND ORGANIZE
• Write with Apple Pencil and combine text notes, images, and PDFs.
• Recognize text with OCR, organize folders, search notes, and create review cards.
• Export and back up your work. Local notes do not require an InkCoach account.
TRANSLATE AND LEARN
• Basic translation runs on your device without a subscription. Language availability depends on system support; downloaded language packs can be used offline.
• Optional remote AI offers dictionary explanations, grammar checks, and expression suggestions with an in-app auto-renewable subscription. Available trials, prices, and terms appear before purchase.
• Preview and confirm selected text before remote processing. AI results do not replace your source text or handwriting.
HELP AND FEEDBACK
• Read the built-in user guide, send suggestions or issue reports, manage drafts, and view replies.
• Available in Simplified Chinese, English, and Japanese.
REMOTE PROCESSING AND PRIVACY
Requests pass through our gateway in Tokyo, Japan, to Alibaba Cloud Model Studio in Beijing, China, for model inference. Original handwriting, entire notebooks, PDFs, and images are not uploaded for AI analysis; only confirmed selected text and necessary request metadata are sent.
