Truly AI detector for iPhone, iPad and Mac

Is it real, or made by AI?

Check a photo, a video or a piece of writing before you trust it or share it. Truly looks for signs of AI generation and face swaps, and shows you the evidence behind every score.

How a check works

  1. Bring it in

    From another app, tap Share and choose Truly. Or paste a link, or pick a photo, video or file.

  2. Let Truly look

    It checks for AI generation and face swaps. Longer videos take a little more time.

  3. Read the evidence

    See the likelihood, what it’s based on, and which AI tools were most likely involved.

A score, not a verdict

Truly’s results are likelihoods, not certainties. For anything that matters, like a news story, a job application or a person you’re about to meet, use them alongside your own judgment.

What you check is processed only to analyze it. Truly doesn’t recognize faces or identify people, and your content isn’t used to train models. Read the privacy policy

Check it before you share it.

A source to verify, an essay to read, a profile that looks a little too perfect.
