Steg.ai alternative: watermarking + C2PA in one API, free to try
Steg.ai provides solid invisible watermarking but no C2PA signing and no free tier. ForensicMark gives you both in a single API call, with a free demo you can try without creating an account.

What is Steg.ai?
Steg.ai is a SaaS platform for invisible watermarking. It uses neural steganography to embed imperceptible signals in images that can survive common transformations like compression, resizing, and format conversion. It's aimed at enterprises that want to track where their visual assets appear online.
Steg.AI — invisible watermarking platform homepage
Steg.ai has a real product with genuine robustness. If invisible watermarking is all you need and you're comfortable with the pricing and lack of a free trial, it can do the job.
Where it falls short: there's no free tier to experiment with, no C2PA support, and no MCP server for teams building AI-native pipelines. If you need Content Credentials alongside watermarking — required for EU AI Act compliance and increasingly expected by content platforms — you'd need to stitch together a separate solution.
Why choose ForensicMark instead
Try before you commit
ForensicMark's free tier gives you 20 embeds and 30 detections per day with no account. You can verify the watermark survives your specific transforms and integrates cleanly with your pipeline before spending a dollar.
One API for watermark + C2PA
The ForensicMark embed endpoint can simultaneously apply an invisible watermark and attach a C2PA Content Credentials manifest. You don't need two vendors, two integrations, or two contracts. Both layers of provenance in one call.

Built for AI-native workflows
The ForensicMark MCP server makes watermarking callable from AI agents. Hook it into your Claude or GPT-4 workflows to automatically watermark every image an agent generates, without writing custom tool wrappers.
DMCA enforcement built in
Through our partnership with CopyrightShark, ForensicMark watermarks can trigger automated DMCA takedown requests when your images are detected being used without authorization. Detection is only the first step — enforcement is the outcome.
