What the tool actually does
Render
A script plus a set of on-screen assets becomes a finished vertical video — voice-over, burned-in captions, transitions and background music, rendered locally.
Compose
For text-first platforms it builds image cards and post copy instead of video, so the same idea can ship in whichever format the platform rewards.
Schedule
Finished posts go into a queue with a target slot. A scheduler running on our own server picks them up and publishes at that time, spreading posts across the day rather than dumping them at once.
Publish
Each connected platform is authorised once through its official OAuth flow. Publishing then goes through that platform's public content API — no browser automation, no scraping, no stored passwords.
Built for one creator team, not for resale
This is not a marketplace product with public sign-up. GUCupload is operated by its author on a private server, and connects only to social accounts that the operator personally owns and administers. There is no multi-tenant dashboard, no third-party client data, and nothing is published to an account that has not explicitly granted access through the platform's own authorisation screen.
The operating panel used to drive it lives at /panel and is password-protected, because it triggers renders and real posts. Everything on this site describes what that panel does.
