When a two-hour video can be understood in minutes, you can take in many of them in a fraction of the time you would spend watching one. Discover new ones, and free up your hours for what matters. Seimai lifts the time limit off YouTube. SMART SUMMARIES With Seimai's Smart Summary strategies, every video becomes a well-structured piece in the creator's own voice, not just a list of bullet points. A short introduction sets the scene, then clear sections you can skim or open up, at a length that matches the video. Written by AI from the full transcript, with the original always one tap away. YOUR DAILY FEED Follow channels New videos from the channels you follow arrive as Smart Summaries automatically, with a notification when each one is ready. The first 2 channels are free; more with a subscription. Discover channels worth following Suggested channels with a line on what each is about, picks from great channels dropped into your feed, and links to share a channel or a whole set of channels with a friend. Follow channels in any language Creators in English, Spanish, Portuguese, French, German, Italian, Chinese, Japanese and Korean, all summarised in your language. The app itself speaks those nine languages too. GO DEEPER WHEN IT MATTERS Summarise any video Search for a video in Seimai, paste a YouTube link, or pick one from any channel's page.
