Google SynthID Detector
by Google DeepMind · official site
- Detects
- image and text
- Free tier
- Portal access, gated.
- Sold to
- Journalists, researchers
What it does well
- This is not a guess — it reads a watermark that is actually there
- Survives moderate cropping, compression and colour edits
Where it fails
- Only detects content from Google models. Silence means nothing about Midjourney, DALL·E or Stable Diffusion
- Absence of a watermark is not evidence a human made it
Our own measurements
Not yet published. We would rather show nothing than repeat a number we have not reproduced — see our methodology for the benchmark design and what we will publish when it has run.
