Palabra: Practice Vocabulary While Reading

Practice vocabulary while reading: translate any word on any site, save it, and use it in your own sentences with AI feedback.

Palabra is a language learning extension for people who read in another language. Select a word on any website to translate it instantly, save it to your personal vocabulary, and learn it by writing your own sentences with AI feedback. A vocabulary builder that helps you actually use a word, not just recognize it. New words turn into words you can actually use. Most vocabulary tools test recognition: "What does this word mean?" But recognizing a word isn't the same as being able to use it. You might know what "ubiquitous" means, but can you drop it into a sentence when you need it? Palabra is different. We test production: can you actually deploy this word? How it works: 1. Capture - Save words while reading. Select any word on any website and get an instant translation. 2. Practice - When you're ready, Palabra gives you a creative prompt: "Tell me a lie using 'właściwie'" or "Complain about your morning using 'ledwo'." Write a sentence. No multiple choice. No flashcard flipping. 3. Get feedback - AI evaluates your sentence in seconds. Not a grade, just quick, helpful notes: what worked, what to tweak, and a natural-sounding version. 4. See real progress - Words move from Saved to Attempted to Active. Your dashboard shows one number that matters: "Words you can actually use." Why Palabra? - No word graveyard. We don't guilt you with "347 overdue cards." - No busywork. Creative prompts, not textbook drills. - No complexity. No deck setup, no card templates. - Cloud sync keeps your vocabulary across devices. Great for sentence mining from web articles: capture words with their real context as you read, no subtitles or video setup needed. For serious self-learners who read articles, watch videos, or take lessons in another language and actually want to remember what they learn.
