How it works

From the page to long-term memory

Collecting words is easy. Word Hunter builds the way back to them, so the words you meet while reading become words you actually know.

  1. Read something you enjoy

    A novel, a news article, an EPUB, a scanned PDF, film subtitles or a free public-domain classic. Every word is marked as new, learning or known.

  2. Click the words that matter

    Save a translation, article, note or picture. The sentence you found it in is kept with it, so every word comes with its own context.

  3. Recall before you reveal

    Flashcards and in-text prompts ask for the meaning first. You check yourself against the original sentence and rate how well you knew it.

  4. Come back at the right time

    Spaced repetition (FSRS or SM-2) schedules each word. Hard words return soon, familiar ones wait longer – no wasted reviews.

Features

Everything a reading learner needs, in one app

No subscription and no cloud lock-in. Your books and words live on your device.

A reader that knows your words

Every word is colour-coded by how well you know it. Click one to translate it, hear it, look it up in a dictionary or save it – without losing your place.

Import almost anything

Paste text or open EPUB, PDF, TXT and Markdown files, SRT, VTT and ASS subtitles, web articles and YouTube captions. Browse Project Gutenberg, Wikipedia and Wikinews in the app.

Scanned PDFs with local OCR

Desktop packages bundle the OCR engine and models. Read the original page with selectable words laid over it, or switch to a clean text view. Nothing is uploaded.

Flashcards with spaced repetition

Review due words with FSRS or SM-2, keyboard shortcuts, pronunciation, reverse cards and shuffling. On reverse cards the answer is masked inside the example sentence.

Your personal word base

Search, filter, edit and clean up every saved word with its status, translation, examples and source. Export to Anki, or back everything up in one ZIP file.

Progress you can see

A review heatmap, a 30-day due forecast and vocabulary growth mapped to CEFR levels show how far you’ve come and what’s coming up.

Word Hunter Pocket for Android

Import on your computer, then read and review on the go. A transfer package carries books, page images, words, settings and progress between devices.

Comfortable reading

Light and dark themes, adjustable fonts and sizes, the dyslexia-friendly Atkinson Hyperlegible and OpenDyslexic fonts, and read-aloud that keeps the spoken word in view.

Optional AI explanations

Ask a local model (llama.cpp, LM Studio, Ollama) or any OpenAI-compatible service you choose to explain a word in its sentence. Off until you turn it on.

Why it works

Built on well-studied learning habits

These studies look at learning methods, not at Word Hunter itself. They show why context, recall, repetition and spacing are worth combining.

Context

“Reading the words in either the retrieval or inference context increased retention.”

van den Broek et al., Cognitive Science, 2022 · Study
Active recall

“Taking a memory test not only assesses what one knows, but also enhances later retention.”

Roediger & Karpicke, Psychological Science, 2006 · Study
Spacing

“The optimal gap increased as test delay increased.”

Cepeda et al., Psychological Science, 2008 · Study
Repetition

“Results showed that there was a medium effect (r = .34) of repetition on incidental vocabulary learning.”

Uchihara, Webb & Yanagisawa, Language Learning, 2019, a meta-analysis of 26 studies · Study

No method works on autopilot: pick texts you can mostly understand, save the words that matter to you, and try to recall before you check.

Languages

Twelve languages, and room for yours

Each language gets its own library, word base, review queue and progress, with original stories and A1–B2 course books built in. The Other profile works with any language you set up.

The app itself is available in English, German, Spanish, French, Italian, Polish, Ukrainian, Russian, Japanese and Chinese.

What’s new

Recent releases

Word Hunter 1.1.2

· Update

  • Imports that work. Wikipedia and Wikinews articles from Discover open again, PDFs saved from a browser keep their words whole, and EPUBs with many pictures or an embedded font are accepted. More YouTube videos have subtitles.
  • One entry per word. French and Italian words after an elision (d’, qu’, dell’), Ukrainian words written with ʼ and Ancient Greek words with a grave accent are saved as the word itself. Words you saved before are merged when you update.
  • Safer backups and transfers. Restoring the backup the clear buttons make brings back what was cleared. Transfer packages no longer carry your DeepL or AI keys, and importing one no longer deletes words on this device just because they were deleted on the other.
  • Flashcards. The review calendar keeps every day you reviewed, deleting a word you have worked on asks first, and reloading right after an edit no longer loses it.

FAQ

Questions, answered

Something else? Ask on GitHub.

Is Word Hunter really free?

Yes. It is open-source software under the GNU AGPL-3.0, with no subscription, no in-app purchases and no ads.

Do I need an account or an internet connection?

No account at all. Reading, saving words, flashcards and desktop OCR work offline. The internet is used only for online features you choose, such as the book catalog, online translation, dictionaries or online speech.

Where is my data stored?

On your device. Your books, words, settings and progress never go to a Word Hunter server – there isn’t one. You can export a full backup as a ZIP file at any time. See the privacy policy.

How do I move my words between my computer and my phone?

Open Export, save a transfer package and import it on the other device. It carries books, page images, words, settings and reading progress, and merges with what is already there.

Can I keep using Anki?

Yes. Export your words to Anki as a TSV file, or import an Anki TSV file into Word Hunter.

Is there an iPhone or iPad version?

Not at the moment. Word Hunter runs on Windows, macOS (Apple Silicon), Linux and Android.
