FLTR is an open source application that helps you to do both extensive and intensive reading as part of your foreign language acquisition in an easy and enjoyable way.
While reading, this application lets you look up unknown words in web dictionaries (requires online access) and save vocabulary terms (words and multi-word expressions) with translations, romanization (like Pinyin, Hiragana, etc., optional) and example sentence (optional). Each term has also a learning status (1/”Unknown” to 5/”Known”, plus Statuses “Ignored” and “Well Known”) with an associated color.
FLTR is in many respects similar to the Public Domain software “Learning With Texts” (LWT). But FLTR is easier to install and to run given that it does not require a personal web server or database. The tool is inspired from LingQ and contains code from Learning With Texts.
Features include:
- Look up unknown words in web dictionaries.
- Save vocabulary terms (words and multi-word expressions) with translations.
- Romanization (like Pinyin, Hiragana, etc.
- Terms have a learning status with an associated color.
- Reads and writes its data (language definitions, texts, terms, export, general settings) in UTF-8 text or TAB-delimited CSV files.
