How it works
Three steps to always-on translation
- 1
Load your documents
Word, PDF, scans and photos: tables and two-column textbooks. The app detects the languages and stitches paragraphs back together.
- 2
Show it what to translate
Select an area with a hotkey, let it follow subtitles, or turn on lecture audio and your microphone.
- 3
Get the exact translation
The translation appears in a small window on top of every app — with its source, page and match score.
Features
Everything you need in class, at exams and at work
Every feature works on top of any app: browser, video player, Zoom, PDF reader.
Subtitle tracking
The app watches the area you pick and translates every new line with as little as 0.1 s delay.
Voice and computer audio
Listens to a video, a call or your microphone, splits speech into phrases and shows the translation before the phrase ends.
Voice-over in your headphones
The translation is read aloud by natural voices in 5 languages — with correct stress and numbers.
Lecture mode
A transcript of the whole class, terms from your documents and an automatic summary. Export to Markdown and text.
Flashcards and Smart review
Cards from a document or your translation history, four study modes and a drill of your weak spots.
Workspaces
A separate set of documents and languages for each subject — switch in one click.
Privacy and panic key
The translation window is hidden from screen sharing, and one key closes the app instantly.
Lecture mode
Class is over — your notes are ready
DocXAssist listens to the teacher or a recording, keeps a transcript and highlights terms from your documents. After the lecture the text is refined by the most accurate recognition model and a summary is built from the key sentences.
- Microphone or computer audio — works for online classes too
- Terms from your glossary, translated right in the transcript
- Summary, export and “To flashcards” in one click
Privacy
Your documents never leave your computer
Text and speech recognition, search and voice-over all run on your own computer. Documents, screenshots and audio are never sent to a server.
Works offline
Internet is only needed to sign in once a week and for updates.
Invisible in screen sharing
The translation window and frame never appear in recordings or streams.
Signed updates
Every update is verified with a digital signature.

Frequently asked questions
What is DocXAssist?
A Windows and macOS app that finds the translation of a phrase in your own documents: textbooks, glossaries, bilingual contracts. Take the phrase from the screen, subtitles or speech — the translation appears in a window on top of every app.
How is it better than an online translator?
An online translator produces a best guess; DocXAssist takes the translation from your document — with exactly the terminology your teacher or client expects. It also works on top of any window, in real time and offline.
Are my documents sent to a server?
No. Documents, screenshots and audio are processed only on your computer. The server only receives your sign-in email and the list of your devices.
How many devices can I use?
Free — 2, Student — 3, Pro — 5. You can unlink a device on the Account page up to 3 times a month.
