Duolisan

Learn Arabic or English from YouTube: vowelled Arabic (tashkil), a translation line, and tap any word for its meaning.

Read the Arabic you hear, with every vowel in place. Duolisan draws two lines over YouTube's own player: the Arabic with full vowel marks (tashkil), and its meaning in your language. You see how each word is said while you hear it, so listening and reading line up. What you get - Full vowel marks on spoken Arabic, dialect included, written as it is spoken. - Tap any word: its meaning, dictionary form, root, grammar and examples. Explanations in English, Arabic, Malay, Indonesian, Urdu, Turkish, French or Spanish. - Explain a whole line: what is said, the dialect, and word-by-word meanings. - Study line by line from the keyboard: previous, repeat, slow repeat, next, and pause after each line. - The word being spoken is highlighted (a light box, not colour alone) on videos with automatic captions. - A transcript panel beside the video: click a line to jump to it. - Save words and lines, practise them as flashcards, and export them for Anki. Saved items stay on your computer. - The other way round too: on a video in another language, that language is the study line and Arabic is the translation. - Stays inside YouTube's player, so fullscreen works. No video or audio is downloaded or recorded. Please read: honest limits - The vowel marks and word meanings come from AI (Anthropic's Claude) and CAN BE WRONG. They are a study aid, not a reference. A warning mark shows where the AI was unsure what was said. - Translations are YouTube's own and can be wrong. - A video needs captions on YouTube (automatic ones count); the extension tells you when there are none. - Free to use with a daily allowance. Duolisan Plus (optional, paid through Stripe's own checkout page) raises it. Privacy in short No account and no sign-in. To vowel or explain a line, the extension sends the video id, the caption lines and a random install id to our server, which uses Anthropic's Claude API. Card details go only to Stripe.
