Frequently Asked Questions
Everything you need to know about our detection methodology and accuracy.
How does Check AI Free detect synthetic images?
Our detection engine checks for high-frequency noise distributions, latent diffusion decoders artifacts, and structural color transitions typical of modern diffusion models such as Midjourney, Flux, and DALL-E.
Can it detect images edited with AI filters?
If an image is partially edited or in-painted, our model evaluates overall pixel variance and highlights mixed or uncertain signals, suggesting manual inspection of fine textures like hands and eyes.
Is it really completely free to use?
Yes. The basic image verification tool on CheckAIFree.com is 100% free with no sign-up required, supported by non-intrusive tech advertisements.
