Anki is an open source flashcard program for spaced repetition that hands the timing of reviews to the FSRS scheduler built into it, and includes a free service for syncing between devices. It suits learners who need to hold a large mass of small facts over the long run.

An open source tool for collecting, organising, annotating, citing and sharing research material. It reads citation data off a web page in one click, inserts citations while you write and rebuilds the bibliography, and keeps PDF annotations tied to the item. Version 10.0.6, AGPL.

Learners collect dictionaries the way other people collect records, and then look words up one book at a time. GoldenDict-ng loads the whole shelf and shows every answer for a single query on one screen.

A few hundred ebooks scattered across a download folder, with mismatched names and formats, is where management stops being optional. Calibre reads metadata on import, fills in covers and series, and converts between formats almost freely.

Eudic is a dictionary tool for Windows, macOS and mobile that lets you import third-party dictionary files and see several dictionaries side by side for one word. It adds selection lookup while reading, a vocabulary book that syncs across devices, and a separate paid tier for its writing features.

An AI translation service whose web translator is free within a monthly character allowance. Its strongest feature is document translation, which returns Word, PDF and PowerPoint files with the original layout still in place.

An open source reader for six platforms that opens more than fifteen ebook and comic formats, keeps everything local by default, and adds cloud sync, four annotation styles, translation and read-aloud for people who want to read rather than manage a library.
