What Vocabulary Builder is for
Build a word list, review it with flip cards and track which entries you keep missing. A lightweight study aid for language learners.
The Vocabulary Builder is part of the Text collection on ToolFlow. It is designed for one concrete job: study words with spaced flashcards. Everything runs client-side, so you can use it with sensitive material without creating a copy on someone else's server.
Common use cases
- Learn exam vocabulary
- Review new words
- Keep a personal glossary
Good to know
- No account is required, and there is no usage limit on the browser tool.
- Processing happens locally. Files are read from disk and the result is written back to your downloads folder.
- Results are reproducible: the same input and options produce the same output, with no hidden server round-trip.
- If the tool needs a live data source, the page states it explicitly instead of silently failing.
