What people ask.

Example questions and answers.

  • Is this real or AI?

    A viral TikTok of raccoons on a trampoline. Sift read 300 comments.

    Sift

    Likely AI

    Snopes fact-checked it and found it AI-generated. Commenters spotted the same thing.

  • Is this true?

    A YouTube Short that says people eat eight spiders a year in their sleep.

    Sift

    False — a fabricated urban legend with no scientific or medical evidence.

    The “eight spiders a year” figure was made up. Snopes and Scientific American both checked it.

  • What song is this?

    A video on X. Sift read 300 replies.

    Lights Up — Harry Styles

    Four replies name it. Every other guess got fewer votes. Sift reads the comments, and checks the audio when they're not sure.

  • What’s the joke?

    A video of a cat asleep in an empty box, next to an expensive new cat bed.

    Sift

    The cat ignores the fancy bed and sleeps in the box it came in.

    Most commenters say that is the joke: cats always pick the box. @boxcat_fan: “The bed cost $80. The box was free. The box wins.”

  • What happened after?

    A reel on Instagram.

    Sift

    Guy goes to jail for DUI and hit and run; his dog Mac goes home for a nap.

    According to the top comment, the man faced jail time while his dog Mac went inside. Most other comments joke that he is intoxicated or high.

  • What’s the recipe?

    A pasta video with no recipe in the caption.

    Sift

    Creamy garlic pasta. The full recipe is in a reply.

    From the comments: @pastaclips lists 200 g spaghetti, 4 cloves of garlic, 1 cup of cream and parmesan. Five replies say it worked.

  • Where’s the next part?

    A TikTok story that ends on “Part 1”.

    Sift

    Part 2 is out

    Sift checked the creator’s posts and found it, posted Sep 28.

  • Where is this?

  • Ask a 1-hour video

    Randy Pausch’s Last Lecture, over an hour. Asked: “When do they talk about brick walls?”

    Sift

    Three moments about brick walls

    • NASA said no, so he found another way in.
    • Brick walls filter out the people who don’t want it badly enough.
    • They separate dreamers from everyone else.

    Jump to 5:54

More than a summary.

  • Real or AI?

    Checks the actual video frames, not only the thumbnail. Sift+ can check harder.

  • Sources you can tap

    News, fact-check and official links that people share in the comments show up as safe, one-tap links.

  • Finds the other parts

    Knows when a post is part 5 and looks for part 6 in the creator’s nearby posts. One tap opens that exact post.

  • Honest about doubt

    Says so when it can’t tell or when people disagree. It waits up to a minute rather than send a weak first answer.
