Pros and cons

ImgAuth

Pros

  • Focused on two clear tasks, document tampering and AI-generated image detection
  • Heatmaps and suspicious-region outputs give reviewers something to check, instead of a bare score
  • Free 3-credit trial with no card, and cancellation at any time with access until period end
  • REST API for higher-volume and team workflows
  • Candid limitations: outputs are described as review signals, with explicit scope boundaries

Cons

  • No published accuracy figures or independent benchmarks
  • Not a deepfake, face-swap, liveness or identity tool, and the site's wording on face-swap detection is inconsistent
  • 10 MB file limit and no free ongoing tier after the 3 trial credits
  • Mobile app is only announced, with an outdated launch estimate (Q2 2025) on the site
  • Operating company is named only as ImgAuth Ltd, with no team or founding details published

Leonardo AI

Pros

  • Free plan with 150 tokens per day
  • Many first-party and third-party image and video models in one account
  • Personal model training on paid plans
  • AI Canvas for inpainting and outpainting
  • Apps for iOS and Android, plus a pay-as-you-go API

Cons

  • Free generations are public and the daily allowance is small
  • Token costs vary by model and settings, so spend is hard to predict
  • Unlimited relaxed video generation needs the $60 Ultimate plan
  • Official pricing page blocks automated access, so plan details need checking on the site
