Local dictionary lookup
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.
THE PRACTICAL VALUE
Why this step deserves its own workflow
Point NurViewer at your local dictionary collection and query supported dictionary formats from the reading workflow. A supplied dictionary can bring its own pictures, pronunciation and cross-references. The reusable lookup window keeps definitions accessible while your book or document remains the starting point.

A PRACTICAL SEQUENCE
Start with the material you actually need.
Check representative material before deciding how much more to process.
- Choose a dictionary folder and inspect the detected books and companion resources.
- Confirm the collection, then query a selected word in a supported reader.
- Save a useful definition with its available context to vocabulary.
EDITION & SCOPE
Know the scope before you commit.
MDict, StarDict, DSL, XDXF, dictd, Babylon, Lingvo LSA, Slob and EPWING have format-specific boundaries. Dictionaries are user-supplied. Free queries one selected dictionary; paid tiers can query all configured books.
Free has no trial expiry: common-format reading, ordinary PDF annotations and supported ordinary document/image-to-PDF export remain available. Recognition, specialist formats and advanced tools have their own allowances or tier requirements.
Compare Free, Standard and Pro →Images may retain historical layouts. Demonstration books, dictionaries and media are not bundled.
A USEFUL QUESTION
What if I have not installed any dictionaries?
The app offers a clear configuration prompt and a settings route. It does not turn a missing folder into a definition or silently download a commercial dictionary.

A useful next step.
Keep reading, understanding and organising around the same material.

Vocabulary with context & export
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.

Clickable subtitle study
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.

Long-form reading notes
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.
