Show HN: Timestamp and provenance records for AI-assisted creative work
Last verified:
What is Colossee?
Colossee is a registry and proof platform for AI-assisted media. It lets you register a piece of work before you publish, sell, or deliver it, then generates a timestamped public record tied to that exact work. The goal is to give creators a verifiable proof page, ownership ID, and certificate-style receipt they can use when authorship is questioned or work is reused.
The product is built around pre-publish proof. You can paste a link or upload media, create a proof record, and then point clients, buyers, or platforms to the certificate page later. The site emphasizes that the proof happens before the work leaves your hands, which is meant to strengthen provenance and authorship claims.
Colossee supports a broad AI ecosystem, positioning itself as a registry for content made or enhanced with many tools across image, video, audio, and document workflows. Its registry feed shows public entries with registry IDs, titles, media types, platforms, statuses, and view counts, which suggests it is designed for public visibility as well as recordkeeping.
It appears most useful for creators, freelancers, studios, and teams that regularly ship AI-assisted work and need a lightweight way to document origin. The product also seems geared toward client handoffs, portfolios, captions, invoices, and dispute scenarios where a proof page can act as a receipt.

Frequently asked questions about Colossee
What does Colossee do?
Colossee registers AI-assisted or AI-generated work before it is published, sold, or delivered. It creates a timestamped public record, a registry ID, and a certificate page that can be used as proof of authorship or provenance later.
What kinds of media can I register?
The site says Colossee works with common image, video, audio, and document uploads, and it also supports links. It is presented as a registry for content created or enhanced across the AI creative stack, so it is not limited to one media format.
When should I create a proof record?
Colossee recommends doing the proof step before your work leaves your hands. The workflow is framed around registering the work before posting, pitching, sending final files, or otherwise publishing it.
What comes with a proof record?
A proof record includes a public record tied to that exact work, a registration ID, and a certificate-style page. The site also highlights timestamped proof and certificate links as part of the output.
How does the credit system work?
The website says 1 proof record costs 10 credits. Credits are deducted server-side only when you create a proof record, so previewing the flow does not appear to consume them.
Is there a free plan?
Yes. The Free plan is for previewing the proof flow, testing the upload process, and previewing a proof record. It includes 0 proof records, and the site says you need to upgrade before publishing.
What do the paid plans include?
Creator is $9 per month and includes 10 proof records each month. Pro is $29 per month and includes 45 proof records, dashboard registry management, and top-ups for launch weeks. Studio is $99 per month and includes 150 proof records, high-volume registration capacity, and public records and certificates.
Who is Colossee for?
The site is aimed at creators, people publishing weekly, client and campaign work, and studios publishing daily. It also positions itself for anyone who wants a proof page for portfolio use, client handoffs, captions, invoices, or disputes.
What is the registry feed?
The registry feed is a live public listing of registered works. It shows entries with a registry ID, title, media type, platform, status, views, and registration age, which makes the registry feel transparent and searchable.
Why would someone use Colossee instead of a normal file upload or portfolio link?
Colossee is designed to attach proof to the work itself, not just to store the file. That matters when you want a timestamped public record and a certificate page you can point to if the work is copied, questioned, or reused.
