The Process
Three steps before you publish
Do the proof step before your work leaves your hands. Then publish, pitch, or deliver with a record already attached.
STEP 01
Add the work first
Before posting, pitching, or sending final files, paste a link or upload the media you want tied to your name.
Works with links and common image, video, audio, and document uploads
STEP 02
Create the proof record
Colossee deducts credits server-side and creates a public record with a registration ID for that exact work.
10 credits per proof record
STEP 03
Publish with a receipt
Use the certificate-style page in portfolios, client handoffs, captions, invoices, or disputes when authorship is questioned.
