Active Dictionary

An unfamiliar phrase in a book carries more meaning than the same phrase on a blank flashcard. Active Dictionary uses that connection as the basis for language practice: choose a text, PDF, or captioned video, then work with vocabulary from that material.

Its public King Arthur reader opens without an account. The site uses phrases such as “days of chivalry” to illustrate how vocabulary can stay connected to a story. That makes the public library a useful place to see the reading format before deciding whether to create a personal project.

The speaking tool is described as an AI conversation about the selected text, video, or document, with saved expressions available in a sidebar. Writing practice follows the same content-based approach. For a learner working through an industry article, for example, explaining its argument could be a more relevant exercise than answering an unrelated conversation prompt.

Those personal practice features require an account. The public pages explain the intended workflow, but the quality of conversations and writing feedback was not assessed for this note.

YouTube imports depend on captions; an arbitrary video will not necessarily work. The PDF page advertises text lookup and OCR for scanned documents up to 50 pages. These constraints matter when choosing source material, particularly if a lecture has no transcript or a scanned book is much longer.

The privacy policy covers uploaded and saved content as well as account information, so personal projects should not be treated as local-only files. Current prices and AI allowances were not established from the public pages reviewed. The clearest fit is a self-directed learner who already has something worth reading and wants to keep vocabulary, discussion, and writing practice close to it.
