Gravity vs Lute

Gravity has no write-up on Specifiction yet; its figures are above.

Lute is a standalone web application installed on your computer for learning languages through reading. Users import or create texts, read them, and save definitions and associations that build a personal dictionary. The application lets users define languages and dictionaries, edit texts, and create single-word or multi-word terms while reading. Parent terms can share definitions with child terms, and sample sentences can include related terms. Readers can add images to words and use hotkeys to set statuses such as New, Learning, Well-known, or Ignore, including bulk updates. Lute supports 66 languages; its manual lists more than 50 predefined languages with sample stories and dictionaries, though some need plugins. Languages can use multiple term and sentence dictionaries, displayed embedded or in pop-up views. Lute can export terms to Anki note types, and AnkiConnect enables communication with Anki. Supported content includes text, TXT, EPUB, web pages, and book audio. Installation options are pip, Docker, or source code; Android use through Termux is also documented. Lute is free, uses the MIT license, and runs locally so users control their data.
