Parlang combines aligned multilingual vocabulary, neutral wording, personal collections, parallel translations, intelligence-enhanced study sessions, baseline checks, and short quizzes. Vocabulary cards remain aligned by meaning, so learners can compare the same concept across selected languages, inspect cognates and differences, then return to the same place. Saved words become vocabulary books for review and self-testing. Books use level checks, learning purpose, habits, preferred notification pushes, and target languages to make daily study less generic. Quick exams turn mistakes into a reviewable list, so the product reinforces retrieval and actual usage instead of only browsing. The intelligence is designed around provider flexibility, giving advanced users more control over quality, cost, and privacy choices.
