Lute

Overview

Lute is a locally installed web app for reading texts in another language and building a personal dictionary as you go. It is a strong fit for self-directed readers who want control over their texts and vocabulary; it is a poor fit for learners who rely on quizzes, word-level audio playback, or automated translation.

Bring in a text, look up unfamiliar terms, and save definitions and associations for later reference. Lute also lets you create and edit texts, configure languages and dictionaries, and record multi-word terms. Parent terms can pass definitions to child terms, while sample sentences can connect related terms. That structure is useful for organizing vocabulary in context, though it leaves review and recall practice to the learner.

Key features

Reading and vocabulary

Lute supports text, TXT, EPUB, web pages, and book audio. Readers can add images to words and use hotkeys to mark terms New, Learning, Well-known, or Ignore; bulk status updates help when many terms need attention. These controls make the personal dictionary manageable, but they do not provide testing. Lute also cannot play audio for a single clicked word and is not intended for automated or bulk translation.

Languages and lookups

The software supports 66 languages. Its manual includes over 50 predefined languages with sample stories and dictionaries, though some require plugins. A language can use several term and sentence dictionaries, with results opening inside the app or in pop-up views. This flexibility suits readers who want to choose their lookup tools; language setup is less turnkey where plugins or extra components are needed. Japanese readers using a non-Docker installation need MeCab and an appropriate dictionary to parse text.

Anki and installation

Lute can export terms to Anki note types, and AnkiConnect enables communication with Anki. That makes it a useful reading companion for people who already use Anki, rather than a replacement for their card workflow. Installation options include pip, Docker, or source code. Lute runs on the user's machine, where the user controls the data; Docker guidance warns that relaxing container permission restrictions can increase host security risk.

Pricing

Free: free. The locally installed plan has no limits, so it suits readers willing to install and maintain their own application without paying a subscription. There is no free trial because the software is free. The trade-off is the installation and configuration work, not a paid tier or usage cap.

Platforms

Lute is listed for Android, Linux, macOS, self-hosted use, web, and Windows. It was designed for desktop and laptop use, but a running instance can be reached from a mobile device. The documented Android route uses Termux, Python, and pip, making phone use possible but more involved than installing a conventional mobile app.

Who it's for

Choose Lute if reading is the center of your language study, you want to build and manage your own vocabulary collection, or you want to connect saved terms with Anki. Its broad language support and local data control are appealing to readers prepared to configure dictionaries and installation. Choose another tool if you need built-in testing, clicked-word audio, or automated translation.

Pros and cons

Pros

No usage limits or subscription: the free local plan has no limits, which suits sustained reading without a quota.

Vocabulary with context: multi-word terms, parent-child definitions, related sample sentences, and word images support a richer personal dictionary than a list of isolated translations.

Flexible reading setup: multiple term and sentence dictionaries can be configured for each language, and terms can be exported to Anki.

Broad language coverage: 66 languages are supported, with over 50 predefined options that include sample materials.

Cons

No testing: learners seeking built-in recall practice will need another tool.

No single-word audio playback or bulk translation: those workflows are outside Lute's reading-focused design.

Setup can involve extra steps: some languages need plugins, Japanese parsing in non-Docker installs requires MeCab and a suitable dictionary, and Android use relies on Termux, Python, and pip.

Alternatives

LingQ is the better fit for readers who want a hosted service with Android, iOS, web, and browser-extension access; its free membership is capped at 20 saved words and phrases, 5 imported lessons, and 1 audio playlist.

OpenKoto is another free option for readers who want an Apache 2.0-licensed app across iOS, Linux, macOS, web, and Windows.

Beelinguapp is an alternative for readers who want Android or iOS access and a free trial.

News in Slow Spanish is an alternative for learners looking for a paid Spanish audio-focused service on Android, iOS, or web.

Readlang is another freemium reading-oriented option with Android, iOS, web, and browser-extension access.

LinguaCafe is a free, open-source self-hosted alternative designed to support one user per server.

News in Slow French is an alternative for learners looking for a paid French audio-focused service on Android, iOS, or web.

Verdict

Lute is the right choice for independent language readers who want an unlimited, locally controlled place to collect vocabulary from their own reading and optionally move terms into Anki. Its main reason to choose it is that reading, dictionary building, and data ownership sit together without a subscription. Look elsewhere if you want the app to test your recall, play a clicked word, or handle bulk translation for you.
