A book should not feel like a folder of web pages. Long chapters, illustrations and footnotes can interrupt your concentration when the reading controls and the reference tools live in different applications.
Explore the workflow →Books & reading
An older digital book may arrive as hundreds of numbered PDG pages rather than a single PDF. Opening every page in a separate image window makes a long reference book unnecessarily awkward to read.
Explore the workflow →Books & reading
A useful book is inside a large archive, but you only want to check its contents. Extracting everything creates duplicate folders and makes it harder to keep the original collection organised.
Explore the workflow →Books & reading
A personal ebook collection rarely uses one format. Converting every older book before you can even inspect a chapter adds another task before the reading has begun.
Explore the workflow →Books & reading
Older technical books and scanned references often arrive as DjVu. A format you rarely see should not prevent you from checking a diagram or reading the chapter someone sent you.
Explore the workflow →Books & reading
A product manual or programming reference may still be packaged as CHM. The file is useful because of its contents, even when its packaging belongs to an older generation of Windows software.
Explore the workflow →Books & reading
Comics, art books and scanned handouts rely on page order and visual continuity. A folder of pictures is difficult to read if every page opens independently and the view keeps changing size.
Explore the workflow →Books & reading
A reflowable book is comfortable on screen, but page numbers move when the display changes. Printing selected material or sharing a stable reference is harder when an EPUB contains illustrations, tables or vertical text.
Explore the workflow →Books & reading
Traditional Chinese, vertical text and heavily illustrated books are easy to misjudge from a format label alone. A reader that handles plain paragraphs can still lose the intended reading flow on a more carefully designed page.
Explore the workflow →Books & reading
You remember a phrase but not its chapter. Repeatedly scrolling through a long book can cost more attention than the passage itself, especially when you return to it days after reading.
Explore the workflow →OCR & phonetic symbols
A copied dictionary entry is not useful if its pronunciation is wrong. Small marks such as stress and vowel length carry meaning, yet can disappear or be confused with punctuation in a scanned English dictionary.
Explore the workflow →OCR & phonetic symbols
When OCR reads across two columns as if they were one line, the characters may be correct but the paragraph is nonsense. Dictionaries, journals and reference pages need the reading order to survive recognition.
Explore the workflow →OCR & phonetic symbols
A photographed handout or scanned page contains words you can see but cannot copy. Retyping the entire page wastes effort when only a paragraph or a few labels are needed.
Explore the workflow →OCR & phonetic symbols
A scan can preserve a page perfectly while hiding every word from search. Months later, finding one term in a thick report becomes a manual page-by-page task.
Explore the workflow →Table recognition
A screenshot of a table is easy to send and hard to calculate with. Copying text often loses columns and empty cells, leaving you to rebuild the relationships before you can do any useful analysis.
Explore the workflow →Table recognition
Many comparison sheets and reports use whitespace instead of grid lines. A generic extraction can turn aligned columns into prose, even though you need a table for sorting and comparison.
Explore the workflow →Table recognition
If a multi-level header is flattened or an empty cell disappears, the exported numbers can move under the wrong label. The result may look tidy while saying something different from the original.
Explore the workflow →Table recognition
A long report splits one table across several pages and repeats its header. Manually joining each fragment in a spreadsheet can introduce duplicate headings or put rows in the wrong order.
Explore the workflow →Dictionaries & knowledge
A quick lookup becomes a distraction when it opens a browser, loses the sentence and gives definitions unrelated to the reference dictionaries you prefer. Technical and bilingual reading often needs a more deliberate choice of source.
Explore the workflow →Dictionaries & knowledge
A highlighted sentence is easy to collect and easy to forget. Real study also needs your explanation, an illustration, a comparison table and enough space to connect them.
Explore the workflow →Dictionaries & knowledge
A word list without the sentence that made the word matter is difficult to review. Rebuilding the same entries in a spreadsheet or flashcard application repeats work you already did while reading.
Explore the workflow →Dictionaries & knowledge
Reading a long passage on screen can be tiring. Hearing supported text while following the original gives you another way to stay with a chapter and notice the flow of the language.
Explore the workflow →PDF & conversion
Feedback scattered across email messages is hard to reconnect with a page. A reader needs to see what matters and leave a clear explanation where the issue actually appears.
Explore the workflow →PDF & conversion
A form arrives as a PDF and asks for a few answers and a signature. Printing, handwriting and scanning it back adds several steps just to return a simple document.
Explore the workflow →PDF & conversion
Reference material arrives as a PDF, but the next task is a presentation. Starting every slide from an empty canvas repeats the extraction and organisation work before you can explain the idea.
Explore the workflow →PDF & conversion
A reflowed Word file can be easy to rewrite but look very different from the original report. Sometimes the task is to change supported wording while keeping the familiar page appearance.
Explore the workflow →PDF & conversion
You need to rewrite a report, not just place a picture of it inside Word. A fixed page is a poor starting point when paragraphs, headings and tables need to move with your changes.
Explore the workflow →PDF & conversion
A recipient wants one convenient PDF, but your source is a document or a collection of images. Hunting for a separate converter for an everyday task adds unnecessary friction.
Explore the workflow →Subtitles & active listening
A useful line passes before you can understand it. Dragging a video timeline back and forth is an imprecise way to find the sentence, and leaving the player to look up one word breaks the listening session.
Explore the workflow →Subtitles & active listening
A difficult sentence needs several listens, but repeatedly seeking to its start keeps turning practice into mouse work. Slowing everything down is also awkward when only one short passage is difficult.
Explore the workflow →Subtitles & active listening
A translation helps you follow a scene, but constantly replacing the original subtitle makes it harder to compare an expression with its meaning. Two useful tracks should be easier to study together.
Explore the workflow →Archives & containers
You receive a mixed package of documents and images, but only need one item. Unpacking the entire folder before seeing what is inside creates extra work and duplicate files.
Explore the workflow →Archives & containers
An old software disc or reference collection is stored as ISO, but you only want to check a document inside. Preparing a virtual drive can be more setup than the inspection itself.
Explore the workflow →Archives & containers
A perfectly usable archive becomes difficult to navigate when its filenames appear as unreadable characters. Guessing names is especially frustrating in a scanned book or collection of similarly sized documents.
Explore the workflow →Batch & document comparison
Preparing many files one by one repeats the same setup and interrupts other work. The real problem is the repeated handling, not simply whether an individual file can be converted.
Explore the workflow →Batch & document comparison
Two documents have nearly identical names, but you need to know what changed. Alternating windows makes omissions hard to see and forces you to remember one version while reading the other.
Explore the workflow →Research & specialist files
A reference arrives as CAJ just when you need to check a citation or a figure. Installing a separate reader for one occasional format makes research feel more fragmented than it needs to be.
Explore the workflow →Research & specialist files
A shoot leaves many similar frames. Opening files individually makes it harder to compare quality and keep the candidates you want, especially when RAW needs its own decoding route.
Explore the workflow →Research & specialist files
A DICOM study is an unfamiliar set of files rather than a normal photograph. For teaching or reference, you need a suitable viewing route before you can even understand what the collection contains.
Explore the workflow →EXPLORE BY TASK
Reading, comments, forms and handwritten signatures belong in the same workflow. Keep the document open and keep moving.
Explore this workflow →Read text from a scan or selected area. Recover useful rows and columns, check the preview, and continue in Excel.
Explore this workflow →Choose editable flow for rewriting, or precise page layout when the original appearance matters. Two different jobs, two deliberate modes.
Explore this workflow →Books, dictionary lookup, vocabulary and reading notes work together, so useful discoveries have somewhere to go.
Explore this workflow →Search names or extractable text across a folder. See what is being checked and what could not be searched.
Explore this workflow →Play supported media, search available subtitles, jump to a line and repeat a chosen section with A–B looping.
Explore this workflow →Inspect ordinary pictures, RAW and supported specialist files. Use the tools suited to the file, rather than treating every format as the same picture.
Explore this workflow →Queue supported files for PDF export, or compare supported document revisions to see what changed. Pro tools for work that comes in sets.
Explore this workflow →MORE EVERYDAY TOOLS
Supported ordinary documents and images export to PDF without a daily page limit or watermark in every tier. EPUB book export is separate.
Pro queues supported files for batch export. Check the supported conversion range rather than assuming every viewable format converts.
Pro compares supported documents to help review changed text and useful differences.
Adjust supported display and reading options, choose the app language and use available read-aloud tools.
Browse supported containers, preview supported entries and extract content without executing programs.
Markdown reading-note export and generic vocabulary export keep personal work portable.

Applies to the updated scanner in version 1.0.2; for an already installed version, follow its in-app limits. Basic crop, rotation, enhancement, multipage scans and ID layout are included within scan allowance.
| Capability | Free | Standard | Pro |
|---|---|---|---|
| New scan pages (camera and import) | 5 successfully processed pages/day | No commercial page cap | No commercial page cap |
| Scanned PDF quality and branding | Balanced, small NurViewer footer | High/lossless, no brand watermark | High/lossless, no brand watermark |
| Flatten curved scanned pages | Included | Included | Included |
Flattening and precise Word layout are available in all tiers. Precise Word shares the existing editable Word/PowerPoint allowance: Free 2, Standard 300 and Pro 1,500 pages/day, with existing branding rules. This is not an additional allowance. Scan and OCR allowances are separate: OCR provides Free 2, Standard 300 and Pro 1,500 pages/day. Multipage searchable PDF requires Standard/Pro and uses OCR allowance. Daily allowances reset at midnight UTC; existing reduced offline allowances apply after prolonged disconnection. Re-editing, cropping, reordering and repeated export do not count again; failures do not count. A retake or replacement photo is a new page. An ID front/back counts as 2, even on one A4 sheet. Originals, drafts and completed results are kept when allowance is exhausted. Existing exports are never retroactively watermarked. Ordinary document/image-to-PDF permissions are unchanged.
