Tool LoR

Tool LoR is a compact browser add-on aimed at learners who grind through web-based language exercises — the kind where you complete fill-in-the-blank sentences, listen to audio prompts, and click through one question after another. Instead of repeating every manual step, the extension takes over the repetitive parts: it inserts the missing word, auto-plays the audio card attached to a question, and automatically moves to the next item once the current exercise is marked complete. Along the way it can store the new vocabulary it encounters so you can revisit it later, and an adjustable timer lets you control the pace at which exercises advance.

The extension is distributed only through the Chrome Web Store and is built by an individual developer (Trần Thành), so it has a small, focused user base and a narrowly scoped feature set rather than the polish of a commercial edtech suite. It ships in Vietnamese and is clearly designed for learners studying on specific web platforms where exercises are served one screen at a time. Because it is free and independently maintained, the experience is best treated as a convenience layer on top of your existing coursework, not as a replacement for actual study.

If you use it, review what permissions it requests and how it handles page content; the developer's listing states it reads website content to detect exercises but does not sell data or use it for unrelated purposes. As with any unofficial study aid, always follow your course or institution's rules about automated assistance.
