Colossee

Colossee operates as a public registry specifically for AI-generated media. Before publishing, a creator uploads or links the media asset, Colossee deducts 10 credits server-side, and issues a permanent public record with a registry ID (formatted COL- plus a unique hash), a timestamped proof page, and a certificate-style link. That certificate can be embedded in portfolio pages, attached to invoices, included in client handoff documents, or cited in disputes where authorship is questioned. The registry feed is publicly browsable, showing registration IDs, asset titles, platform of origin, and verification status.

The core differentiator is that the proof record exists before the content is published anywhere. Unlike a social media post timestamp or a platform’s internal metadata, the Colossee record is independent of any distribution channel and predates publication — which is the point a dispute almost always turns on. The vendor states that the registry covers content created or enhanced by any platform across the AI creative stack, listing over 40 named tools including Midjourney, OpenAI, ElevenLabs, Runway, Suno, and Stability AI.

Colossee fits tightly into pre-publish workflows for creators who publish frequently and need a paper trail for client-facing or commercially sensitive work. The free tier, per the vendor’s pricing page, allows previewing the proof flow but does not include completed proof records — publishing without paying is not an option. The credit model means high-volume studios registering tens of assets weekly will exhaust lower-tier allocations and face a choice between upgrading or batching registrations. There is no API access, which means no automated integration with existing content pipelines; every registration is a manual action.
