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  • Mobile app is only announced, with an outdated launch estimate (Q2 2025) on the site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

Runway

Pros

  • Combines video, image and audio generation and editing in one workspace
  • Offers Runway's own Gen-4.5 plus third-party models such as Seedance 2.0
  • Creative Agent builds videos from a conversation
  • Runway Dev API with Node and Python SDKs
  • Free plan with 125 credits that do not expire
  • Native iOS and Android apps

Cons

  • Credit-based pricing: a 5-second Gen-4.5 clip costs 60 credits, so the 625 credits on Standard cover about 10 such clips
  • Standard and Pro credits do not roll over at the end of the month
  • Some App Store reviewers complain about the cost of failed or unusable generations
  • 4K upscaling is unlimited only on Pro and Max
