When you watch a YouTube video, you may catch some phrases you want to learn, some phrases you don't understand, or some good phrases you want to share.

SayJack offers an online language learning community for you to post a short YouTube video clip, and let the language learning community continue the discussion and language learning process in a systematic way.

To start, post a YouTube video URL link below. You will choose the start time and end time of the video to generate a video clip in the next steps. Other SayJack users will then be offering help by transcribing the video clip, telling you how to say it in other languages, and showing you how to say the sentence more slowly and clearly. You may also practice speaking the sentence.
